    In December 2022, the Ministry of Health, Labour and Welfare (MHLW) of Japan issued and implemented the guideline for evaluating the effects of psychotropic drugs on motor vehicle driving performance. This guideline recommends the use of a tiered approach to assess clinically meaningful driving impairment. It is noted that adverse events cannot be solely explained by pharmacokinetics, as the onset and duration of these events vary. Among these adverse events, those affecting alertness, such as drowsiness caused by psychotropic drugs on driving performance, are more frequently observed during initial treatment stages and dose escalation. Hence, when evaluating the effects of psychotropic drugs on driving performance, it becomes crucial to assess the persistence of clinically meaningful impairment. Therefore, the MHLW guideline, developed by the authors, emphasizes the need to assess the temporal profile of adverse events affecting driving in all clinical trials. Additionally, the guideline states that when conducting driving studies, the timing of multiple dosing should consider not only the pharmacokinetics of the investigational drug but also its tolerance.

    Objectives: To keep older drivers safe, it is necessary to assess their fitness to drive. We developed a touch screen-based digital Clock Drawing Test (dCDT) and examined the relationship between the dCDT scores and on-road driving performance of older drivers in a community-setting. Methods: One hundred and forty-one community-dwelling older drivers (range; 64–88 years old) who participated in this study were included in the analysis. Participants completed the dCDT, the Mini-Mental State Examination-Japanese (MMSE-J), and an on-road driving assessment. We examined the relationship between dCDT scores using the method by Rouleau et al. (maximum 10 points) and the on-road driving performance based on a driving assessment system originally developed by Nagoya University. Results: Multiple regression analyses showed that errors in the driving test were associated with dCDT score for the items “confirmation,” “turning left” and “maintains driving lane position”. Discussion: This study confirmed the relationship between the dCDT score and driving errors, such as confirmation, turning left and maintaining driving lane position. The increase in these errors indicates a decline in visuospatial ability while driving. The dCDT score may reflect older drivers’ visuospatial abilities while driving.

    Driving style assessment plays an important role in intelligent transportation system (ITS) applications, such as driving feedback provision and usage-based insurance. Many previous studies used supervised algorithms to profile drivers. However, this cannot be applied to large-scale unlabeled driving data, which are increasingly prevalent in the ITS context. This paper proposes a framework that combines lateral and longitudinal accelerations to assess a driver's driving style using an unsupervised approach. The framework first detects risky acceleration maneuvers using a statistical method based on the G-G diagram that shows combinations of lateral and longitudinal accelerations. Hierarchical clustering was used to classify the average driving behavior of drivers into high-, medium-, and low-risk groups. Further, a unique Gaussian mixture model is trained for each driver to score their driving style and decompose risky acceleration maneuvers into several risk components. Finally, the spatio-temporal characteristics are extracted to provide implicit factors on the risky behavior of drivers. The proposed method was applied to a large-scale dataset obtained by in-vehicle data recorders. The results demonstrate the necessity to combine the two axes of acceleration for driver behavior assessment. The proposed method can model individual driving styles effectively from the driver's G-G diagram, enabling applicability to large-scale unlabeled data for driving style assessment. The extraction of spatio-temporal characteristics can improve the interpretability of the results obtained using machine learning algorithms. All these results can be used to create a driver's risk profile and provide tailored feedback for improving driving safety.

    In December 2022, the new guideline for evaluating the effect of psychotropic drugs on the performance to drive a motor vehicle was issued by the Ministry of Health, Labour and Welfare (MHLW) and implemented in Japan. Of the safety information, information on the influence of medications on driving performance is particularly important because it can be relevant to the social functioning of patients. In principle, the package inserts of medications are designed based on evidence and provide precautions regarding the operation of heavy machinery such as automobiles in Japan, the United States, and Europe. The effects of medications on driving performance are generally evaluated in a tiered approach involving nonclinical and clinical studies. Because of the wide variety of functional domains involved in automobile driving, the selection of evaluation methods for a given medication depends on their characteristics, which is a complicated method. Therefore, to evaluate the effects of psychotropic drugs on driving performance efficiently and appropriately, we developed the MHLW guideline that specifically defines the evaluation methods used in pharmacological studies, the neuropsychological tests used in pharmacodynamic studies, and the situations in which driving studies are necessary. Regarding the planning of appropriate drug development strategies, we review the background of the MHLW guideline and its differences from the US Food and Drug Administration (FDA) guideline.

    In the previous study, we developed a risk assessment test using a touch panel display, and attempted to measure self-monitoring ability based on the relationship between actual performance and its self-estimation. In this paper, in addition to this, we examined the relationship between the intention to compensate by velocity selection and the actual driving behavior on the road. In this study we increased the number of participants. In addition to this, a certified driving instructor rode along with the participants to evaluate their driving. Actual performance on the risk assessment test was uncorrelated with self-estimation of the test result. The self-estimation of the test result and the velocity considered appropriate for driving the same road again on the test were also uncorrelated. On the other hand, there was a significant correlation between the appropriate velocity selected on the test and the number of times the instructor rated the velocity as inappropriate. An analysis of variance of the two factors, with the adequacy of the self-assessment and the duration of the TMT-B time required as factors, revealed a significant interaction, with the group whose TMT-B time required exceeded 33.4 seconds (Median) and whose self-estimation deviated from the actual performance by more than 10% having significantly lower instructor driving score than the other groups.

    The SQ-CCDC, a simplified questionnaire with a variety of driving-related variables, was developed using items that can represent differences among elderly drivers, and it is better to be able to provide feedback immediately after answering in order to operationalise it. It is not realistic to estimate the latent rank of respondents from their response patterns using LRT software. It is more practical to be able to estimate the latent rank from the sum score. In this report, we examined the cut-off points so that ranks can be analogously estimated from the sum scores of each subscale.

    Objective: A driver’s internal state is a critical factor influencing driving performance, especially in cases of surprise or shock in response to unexpected incidents while driving. This study was designed to investigate the brain activity of a senior driver in response to simulated unexpected vehicle motion, compared with a relaxed state and normal driving. Methods: To accomplish this, we created a driving simulator paradigm wherein participants were involved in one of the following three scenarios: sitting down and relaxing, normal driving around the city with traffic signals and other vehicles, and the exiting of a parking area. In the scenario where the driver was to exit the parking area, the gear was switched automatically by the CarMaker software without the driver being notified, leading to an unexpected condition. The driver’s internal states were classified by artificial intelligence, based on information obtained through four-channel near-infrared spectroscopy. Results: Significant differences were observed between the hemodynamic responses obtained in the three conditions. Ultimately, this method can be used to update advanced driver assistance systems, with a view to preventing future traffic accidents, by activating in-vehicle safety functions based on the driver’s condition. Conclusions: A driver’s internal states in a panic situation while driving can be detected using near-infrared spectroscopy and artificial intelligence.

    <p>Recently, traffic accidents caused by senior drivers have attracted public attention and have encouraged some senior drivers to voluntarily give up their driver licenses. On the other hand, problems have been pointed out, including a decreased motivation to live and an increased risk of needing long-term care due to giving up driving. In order to support the mobility of the senior, there is an urgent need to obtain knowledge on driving support such as effective driving aids and environmental improvements. Of the data accumulated by the Center of Innovation (COI) Program, which is a research result development project of the Japan Science and Technology Agency (JST), the current report focuses on the questionnaire items on driving environments that senior people find reluctant. The questionnaire items ask for an evaluation on “the frequency of encounters” and “the degree to which one does not want to drive” for 24 different driving environments. Using the responses of 216 senior people (55 to 87 years old), analysis by the latent rank theory was carried out. As a result, it was possible to classify the senior into five groups. Depending on the characteristics of the senior people, their evaluation of the driving environment was different. It was found that the perception of the driving environment differed among the subgroups of senior people.</p>

    Understanding driver's foot behavior helps reduce pedal-related traffic accidents. Conventional systems introduced wearable devices to track drivers' foot motion and tracking drivers' feet using non-contact sensors is still challenging. Moreover, to better understand driver's foot behavior, it is required to stably track drivers' small foot motion and at the joint level. To cope with this problem, we develop a novel foot motion tracking system, referred to as 'JointFlow.' This system integrates a pose estimation model, i.e., OpenPose, with Optical Flow. At first, a keypoint region-based convolutional neural network (keypoint R-CNN) is trained to detect the joints of the foot. At the same time, the Lucas-Kanade algorithm of Optical Flow is used to calculate the motion of each foot joint between consecutive frames. We implemented and evaluated the system using a real-world driving dataset of 50 drivers. The evaluation result shows that JointFlow could track both small and large foot motion. By comparing with the conventional pose estimation model, we could confirm that JointFlow tracked small foot motion more stable.

    Many studies on driving behaviour and human characteristics often use multiple questionnaires, that is burdensome for older drivers. It works efficiently if only valid items are used to adequately represent differences among older drivers. The aim of the present report is to develop an exhaustive questionnaire incorporating several driving-related scales. The analysis was conducted using the latent rank theory. As a result, the 121 items of the existing questionnaire could be reduced to 45 items without significant loss of information. With the new questionnaire, it is possible to measure 8 different subjective assessments, such as safe driving orientation and awareness of change.

    The 38-item Workload Sensitivity Questionnaire (WSQ38) was originally designed for general drivers. In this study, we attempted to create a shortened version for senior drivers. As a result of analysis using latent rank theory, we were able to classify the items into three groups of ranks according to the degree of subjective workload. A shortened form was proposed and validated using the top items with the highest item discriminancy. It became clear that about 10 to 9 items were sufficient to measure the degree of driving workload (WSQ9 or WSQ10).

    Sixty-five elderly drivers participated in an experiment to develop a risk estimation test that can measure self-monitoring ability. The test consisted to point hazards, blind spots, signals and road sign by touching display in a Three-Dimensional Computer Graphics (3DCG) image from the driver's viewpoint on a 21-inch touch panel display. After the test, participants were asked to self-evaluate the rate of the total objects they could touch for safety, and to select a velocity for their next driving. The results were compared with those of non-elderly drivers. And the relationship with cognitive function measured by the TMT-B was also examined. In addition, the variables affecting velocity selection were analyzed. The results revealed the following points. The hazard pointing rate of elderly drivers was significantly lower than that of non-elderly drivers. There were many elderly drivers whose self-estimation of the hazard pointing rate was high, even though the actual rate was low. There was a significant correlation between the decline in cognitive function and the decline in the potential hazard like blind spots at intersections pointing rate. There was no relationship between cognitive function or self-estimation of hazard pointing rate and selection velocity.

    This paper discusses driving styles while overtaking a vulnerable road user who moves along the shoulder in urban roads. Based on the data obtained from an experiment in pre-defined conditions (combinations of four main effects: Vehicle’s initial speed, lane width of the road, vulnerable road users’ type, and location in the shoulder) with an immersive driving simulator, we analyzed four different driving styles of drivers while approaching and passing the objects. It is shown that drivers took avoidance maneuvers even if there was no clear risk of collision to vulnerable road users. The results showed that the drivers tended to have a unique perception about the lateral passing gap and overtaking strategy with two worth notice groups: Overcaution drivers and reckless drivers. The road characteristic has a statistically significant effect for all types of drivers. Moreover, the effect of the vehicle’s initial speed on overtaking strategy and the effect of vulnerable road user location on minimum lateral passing gap are statistically significant. The findings provide some implications for the development of automotive safety systems that can reduce the risk of overtaking maneuvers in urban areas.

    The aim of this study is to collect basic data for the prevention of accidents caused by pedal misapplication among the elderly. We hypothesized that frequent pedal changes in parking lots would increase the variance of the foot position on the brake pedal. We install on-dash cams in cars owned by elderly drivers and asked them to drive freely. The results supported the hypothesis. It is possible that this large variance may be a cause of the pedal misapplication.

    Pedestrians and cyclists account for a large proportion of traffic accidents in Japan. In this report, we investigate the driving behavior of general drivers when they pass by pedestrians using a driving simulator. Some factors influencing driving behavior included attributes such as road width and pedestrians, as well as the presence or absence of oncoming traffic and distance from one's vehicle. The results show that the two driver types can be categorized into drivers who perform safe driving behaviors when crossing pedestrians and drivers who are slightly less safe, and these two driver types have very different driving behaviors.

    In the present study, we conducted a questionnaire survey to clarify the effects of the COVID-19 epidemic on the physical and mental health of elderly people and the changes in the feelings of elderly drivers toward driving. The number of outings, which decreased during the period of emergency declaration, gradually recovered to the level before COVID-19 epidemic. However, the number of outings for leisure and social activities did not recover. The number of times they used public transportation decreased, and the number of times they used cars driven by others increased. In addition, the number of times they drove by themselves decreased slightly, and their anxiety about driving by themselves increased. Furthermore, communication with others was association with mental health in the elderly. There is concern that the COVID-19 epidemic may cause a decline in quality of life in the elderly.

    Recently, the number of traffic accidents involving elderly drivers has been increasing, and it is known that side collisions at the intersection are particularly frequent. Thus, we put on-dash cams for 22 drivers aged 50-82 years old to measure their driving behavior at stop intersections. The relation between emergency braking frequency and looking behavior, and cognitive/physical characteristics and driving attitude were investigated. The results show that some elderly drivers can perform compensatory driving behaviors such as looking both ways at stop intersections to reduce the frequency of emergency braking even though their cognitive and physical characteristics have deteriorated.

    Japan has become a more aged society and there are more drivers, 65 years of age and above. Cars represent an important mode of transportation for the elderly; however, in recent years, the number of traffic accidents caused by elderly drivers has been on the rise, and this has become a social issue. Thus, to ensure driving safety, we study a driver agent system that provides driving and feedback support to the elderly drivers for encouraging them to improve their driving. In this paper, we present a summary of the proposed agent and report on a set of experiments using our agent for the elderly and non-elderly drivers in an actual environment with car on public roads. From the analysis of driving operations and fixation points during driving, the results revealed that the acceptability of the agent was high, the agent in the actual car environment did not distract the driver, and the agent could improve driving behavior.

    With the aim of developing a method for evaluating driver distraction based on the difference between simulated and observed eye movements, we integrated a vestibulo–ocular reflex (VOR) model and an optokinetic reflex (OKR) model. On the basis of 2 × 2 factorial design analysis (VOR model only and VOR+OKR model; with and without visual stimulus), we confirmed that the VOR+OKR model showed a better performance than the VOR model, with a smaller mean-square error. We also conducted an experiment that used an n-back task to simulate mental workload while driving. The mean-square error between the simulated and observed eye movement became larger in the presence of mental workload. This result suggests that the VOR+OKR model could be applied in the evaluation of driver distraction.

    In this study, we used robot which was the most acceptable among ´voice´, ´vision´ and ´robot´ as a driver-agent. We verified whether the driving behavior improvement by driving the driving simulator together with the agent. The agent's support was 3 kinds of "driving-support", "feedback" and "driving support and feedback". Driving-support was real-time support by robot's voice. Feedback looked back on unsafe driving behaviors with movie after driving. Driving-support and feedback was combined use of both. As a result, driving behavior was improvement by using an agent. Driving behavior was the most improved condition was "driving-support and feedback". And, the condition with higher subjective evaluation was "driving-support and feedback".

    This study attempted to identify factors associated with driving behavior of elderly drivers to assess their safety and estimate their risk during naturalistic driving. We performed binomial logistic regression using self-reported past crash involvement as a response variable to identify critical factors and provided an estimation model has 18 variables. However, applying driver category based on crash and near-crash events (CNCs) collected from naturalistic driving study employed on-dash cam instead of self-reported crash involvement to the previous model showed lower predictive performance (0.63 for sensitivity and 0.51 for specificity). This implies that the model based on self-reported crash experiences was difficult to detect for drivers with CNC during naturalistic driving. Then, we performed binomial logistic regression based on CNC involvement and indicated another model, where the predictive performance was improved, with 0.81 for sensitivity and 0.70 for specificity. To predict the number of CNCs as drivers’ risk, this study adopted Poisson regression analysis using nine variables selected from the second model. The analyses showed a plausible model and significant variables for the estimation of CNCs. Mini-Mental State Examination (MMSE) was one of the better predictor putting in this model, and showed the probability that lower performance associated with higher number of CNCs. This model for CNC estimation would be helpful for the development of safety programs for elderly drivers with possible incidents.

    <p>Although drivers' driving habits have been investigated using self-report methods, some studies have reported inconsistency between self-reported driving exposure and actual driving data. Data on self-reported and objective driving exposure were collected from 66 drivers aged 50&#8211;83 years. Agreement between these measures was 0.07 and 0.03 for distance driven per day and number of days driven per week, respectively. Factors related to agreement between the two measures investigated, and the odds ratios computed by a binomial logistic analysis for gender and some attitudes (confidence to driving, hesitation about driving, and car as self-expression) were higher than those for other variables. Scores on these variables did not differ significantly between under- and over-estimated self-reports. These findings suggest that the direction of inconsistency between self-reported and objective driving exposure might involve different and general personality traits. Further, self-reported driving exposure may be affected to monitoring experiences brought by attitudes about driving.</p>

    Near-infrared spectroscopy (NIRS) is a promising solution for classifying mental workload while driving, which is important for creating a support system and preventing traffic accidents. Most of the existing research classified mental workload levels via machine learning or deep learning algorithms, where the sliding window time plays an important role in obtaining the features. This study investigated a novel classification of mental workload level using NIRS data by the difference of sliding window time in both channel-independent and subject-independent scenarios. Five sliding times from 1 to 5 s were tested for classification of the mental workload level in 60 experiments in the naturalistic condition. The results indicated that the sliding times were not significantly related to the accuracy of classification using NIRS data when the sample size was just enough. Furthermore, this study succeeded in indicating the driver mental workload using NIRS information in the naturalistic situation with autocross and car-following conditions with an accuracy of over 80%.

     This study investigated which factors affect the usability evaluation of an ACC (Adaptive cruise control). In the experiment, the participants drove a Toyota Prius car with an ACC on real highway. 215 different kinds of driving data were sampled at 60 Hz during driving. At each of the six designated stop points set on driving course, the participants stopped the car and evaluated the usability of the ACC by answering Usability Questionnaire for Automation System. The participants’ driving styles were measured with Driving Style Questionnaire. As results of multiple regression analyses,we found how the participants’ driving styles, the driving control of the ACC, and the participants’ intervention in the driving control of the ACC influenced the usability evaluation. The results were discussed in terms of the human-automation interaction and the design principles of an ACC.

     This article reviewed the association between safe driving and cognitive impairment in elderly individuals, and discussed leaving problems about assessing elderly drivers for fitness to drive and facilitating their mobility. This review placed particular emphasis on the concept of mild cognitive impairment (MCI), which has been used in clinical practice and research over the last two decades. The technical term “MCI” has been based on various criteria, contributing to the difficulty in achieving a consistent explanation of the results from previous studies. Each diagnosis was therefore summarized at first, then previous studies were reviewed to gain an understanding of the impact of cognitive decline on driving safety in drivers with MCI and dementia. Findings of previous studies were also classified into each cognitive disorder due to specific disease (e.g. Alzheimer’s disease; Perkinson’s disease; Lewy body disease; frontotemporal lobar degeneration). Finally, the needs of future studies regarding safe-driving and mobility maintenance for elderly individuals are discussed.

    We have developed a method to estimate driver distraction by mean of involuntary eye movement of the vestibulo-ocular reflex (VOR) and optokinetic response (OKR) by using a driving simulator. This paper presents a practical application of the method to the real vehicle situation. The main concern was whether we can measure the eye movement of VOR and OKR caused by the road surface vibration in the situation. The experiments were conducted with participants sitting on the passenger seat for safety reasons. The results have shown that our method can be applied for evaluating cognitive distraction not only in a driving simulator but also in actual vehicles.

    In the transportation sector, fuel consumption model is a fundamental tool for vehicles’ energy consumption and emission analysis. Over the past decades, Vehicle Specific Power (VSP) has been adopted in a number of studies to estimate vehicles’ instantaneous driving power. Then, the relationship between driving power and fuel consumption is established as a fuel consumption model. However, this paper has discovered that driving power is not the only factor that indicates vehicles’ fuel consumption. Thus, this study proposes a new methodology for a fuel consumption model development based on fundamentals of hybrid powertrain operation characteristics, which aim to minimize error from the conventional modeling method. First, this study introduces a new driving power estimation equation calibrated for Toyota Prius generation 3. Then, Traction Force-Speed Based Fuel Consumption Model (TFS model) is proposed. By combining these two processes together, it provides a significant improvement on fuel consumption prediction error compared to the conventional VSP prediction method. The absolute maximum error was reduced from 57% to 23%, and more than 90% of the predictions fell inside the 95% confidential interval. In addition, the results show that the proposed model well captures the efficiency variation of the hybrid powertrain. This model is also applicable throughout a variety of real-world traffic and driving conditions.

    Recently, traffic accidents caused by elderly drivers have been increasing. It is thought that the reason of accidents is decline of driving skill caused by aging. In order to assist driving according to driving skill of elderly drivers, it is necessary to evaluate senior driver’s driving behavior. In this paper, using driving school instructor's driving as safe driving, the safe driving ability including elderly driver was evaluated by driving behavior at stop sign intersection measured by drive recorder. Using the evaluation method and criteria, relationship of elderly driver’s cognition, physical strength and driving behavior was studied.

    <p>This study examined subjective assessments to clarify how agents for assistance with driving are accepted. The assessors were of various ages, including some who were elderly people. Three kinds of agents were assessed: voice, virtual and robot agents. The results showed that both the elderly people and people in other age groups positively assessed robot agents on the item ‘Familiarity’. The results also indicated that robot agents received lower assessments on the item ‘Obstruction’ than did voice or virtual agents. From these findings, robot agents are considered to be well accepted and tend not to cause hindrances. Moreover, the results changed after repeated use of agents, suggesting that continued use has an impact. Therefore, future directions for research include the following: differences in reception depending on differences in the types of robot agents, changes in assessments when agents are used over a long period of time, and changes in behaviors after driving with the assistance of agents.</p>

    The main purpose of this study is to investigate the effect of visual stimulus on voluntary eye movement during driving. In this paper, we examine two cases: driving with/without visual stimulus by means of a driving simulator. We develop a model that consists of both vestibulo-ocular reflex (VOR) and optokinetic reflex (OKR) components. By comparing the observed eye movement and the simulation result of the model, the results of eye movement simulation was more accurate than VOR model only even in a naturalistic situation with optic flow of the visual scene and the driver’s voluntary eye movement.

    Socially assistive robots have been used successfully for improvement of communication skills of young children. Such robots need to attract children's attention and stimulate sustainable interactions. Many recent research studies propose various approaches for increasing of interaction effectiveness of such robots. In this study, we investigate the effect of robotic movements with animacy on the visual attention of young children. For the experiments, we used the TurtleBot robot. The effect of three different robot movement patterns were explored with the conducted tests: simple circle movement, inanimated movement, and animated movement. Thirty four children (21 males, 13 females, Mean of ages: 4.5) participated in an experiment. Results show that robot movement raises visual attention. Most of the children demonstrated increased interest toward animated robotic movement than simple motion. The animated movement that elicits much interest depends on children's age. The findings of this study contribute to effective use of interactive robots in education and therapy of young children and children with developmental disorder.

    Cardiovascular disease (CVD) is a considerable risk factor of driving. The pain of cardiac events distracts driver's concentration, and ischemia brought by the CVD induces incapacity of driving. In this study, a prototype of the automated safety vehicle stop system has been developed. The system collects bio-signals through the steer-sensor and recognizes the driver's posture by a camera, and detects driver's incapacity. The system takes over the vehicle maneuver when the driver lost his capacity, and automatically drives to a safety spot by sensing the traffic environment. The system has been demonstrated in a prepared emergency scenario and verified the potential. This paper describes the concept and configuration of the system, and a future prospect of the study.

    In recent year, the number of traffic accidents caused by elderly drivers has increased. The effect of changes associated with aging in physical functions and cognitive functions is pointed out as one of the reasons. However, the car is one of important transportation for elderly. Therefore, the assistance measure to realize the safety driving for elderly drivers is needed. To overcome the problem, we are developing the agent that supports elderly drivers. The agent provides the advisement to elderly driver during driving a car and also encourages the driver to improve their driving behavior by showing their past driving records. In this paper, we described the analysis of human instructor's teaching model for considering the supporting method by the agent. From the analysis, we categorized the instructions into several groups and obtained findings about the impression of trainee caused by the instructions.

    To discuss the development of driving-assistance systems and enhancement of driving ability, we investigated stimulus-response behavior among elderly people by using the driving aptitude test. Participants were 100 drivers and were assigned to 3 groups based on age: 50s, 60s, and over 70. All participants provided informed consent and performed several cognitive tests and the driving aptitude test including 7 kinds of tests similar to those in the Lecture for Elderly Drivers in Japan. Analyses of response times and accuracy obtained from 4 of the 7 tests showed that participants in the 60s and over-70 groups delayed their responses when they were required to discriminate among various signals and respond using the foot pedal; and showed decreased performance under the blue-signal condition. The results helped determine elderly drivers' stimulus-response behavior from the driving aptitude test data and indicated a factor-induced performance decrease during driving.

    This study aimed to develop a simple method that can predict the car-following tendency of the driver. Based on the analysis of the naturalistic driving data, some parameters such as the throttlepedal released timing and the average deceleration by braking were found to be correlated with the braking timing. Therefore, the car-following tendency was predicted by a model with those parameters. The model was evaluated on the public road and it was shown that the proposed method can predict the car-following tendency well within a short distance.

    It is important to understand the driver's car-following tendency to enhance the effectiveness as well as the acceptance of advanced driving support systems. If a system can estimate the driver's usual car-following tendency, it can provide avoidance support matched to his/her sense of normal safety driving when the vehicle is approaching a preceding one. Since the car-following tendency varies not only between drivers but also within a driver by the feeling and/or the driving environment, real-time estimation is essential. This study introduces a method that can easily predict the car-following tendency. The method uses such parameters as the throttle-pedal released timing and the braking timing that were found to be correlated from the naturalistic driving data analysis. It was found that the method can predict the car-following tendency within a short distance. We applied the method to a forward collision warning system and confirmed the potential benefit of the system.

    <p>This project aimed to establish a methodology for the use of driving support systems to help ensure the safety of drivers with visual field loss, and to raise public awareness about this methodology. First, driving simulators (DS) were used at medical institutions to construct a database and identify the particular causes of accidents involving visual field loss. The project then studied conditions for driving support systems to counter these accident risks, focusing on automatic braking and audio guidance. Using these results, information about the utility and effectiveness of driving support systems was communicated widely throughout society as a whole and to the relevant institutions using visual field loss as an example, thereby helping to popularize advanced driving support systems and raise awareness about safety.</p><p>In this project, self-organizing map (SOM) analysis of the results obtained from the simple DS was able to identify patterns of visual field loss and situations in which accidents are more likely to occur. It was also found that, using both simple and high-precision DS, accidents involving drivers with visual field loss could be reduced using highly sensitive sensors and automatic braking, as well as by providing specific audio directions rather than simple guidance about the vehicle status. In contrast, the results also showed that automatic braking systems that are unable to completely prevent accidents may actually cause accidents to increase. Additionally, communication of these ideas to society as a whole was started by opening the first safe driving outpatient care programs at two eye clinics using the simple DS results.</p><p>As described above, this project underlined the pressing issue of drivers with visual field loss and proposed ways to resolve this issue. It will be necessary to raise the awareness of both drivers with visual field loss and eye doctors, and comprehensive measures to communicate this issue to society as a whole, industry, and government ministries will also be important. It is hoped that this project will help to resolve technical issues, while leading to changes in vehicle markings, rules, and other non-technical aspects.</p>

    Recently, traffic accidents caused by elderly drivers have been increasing. It is thought that the reason of accidents is decline of driving skill caused by aging. In order to assist driving according to driving skill of elderly drivers, it is necessary to evaluate senior driver's driving behavior. In this paper, using driving school instructor's driving as safe driving, the safe driving ability including elderly driver was evaluated by driving behavior at stop sign intersection measured by drive recorder. Using the evaluation method and criteria, relationship of elderly driver's cognition, physical strength and driving behavior was studied.

    To discuss the development of driving-assistance systems and enhancement of driving ability, we investigated stimulus-response behavior among elderly people by using the driving aptitude test. Participants were 100 drivers and were assigned to 3 groups based on age: 50s, 60s, and over 70. All participants provided informed consent and performed several cognitive tests and the driving aptitude test including 7 kinds of tests similar to those in the Lecture for Elderly Drivers in Japan. Analyses of response times and accuracy obtained from 4 of the 7 tests showed that participants in the 60s and over-70 groups delayed their responses when they were required to discriminate among various signals and respond using the foot pedal; and showed decreased performance under the blue-signal condition. The results helped determine elderly drivers' stimulus-response behavior from the driving aptitude test data and indicated a factor-induced performance decrease during driving.

    In recent year, the number of traffic accidents caused by elderly drivers has increased. The effect of changes associated with aging in physical functions and cognitive functions is pointed out as one of the reasons. However, the car is one of important transportation for elderly. Therefore, the assistance measure to realize the safety driving for elderly drivers is needed. To overcome the problem, we are developing the agent that supports elderly drivers. The agent provides the advisement to elderly driver during driving a car and also encourages the driver to improve their driving behavior by showing their past driving records. In this paper, we described the analysis of human instructor's teaching model for considering the supporting method by the agent. From the analysis, we categorized the instructions into several groups and obtained findings about the impression of trainee caused by the instructions.

    The eco-engineering system combining the industrialization of agriculture, forestry and fisheries to create the [1+2] industry with the hybrid utilization of renewables with fossil fuels will reduce the natural eco-system degradation and promote the development of the renewables. The hybrid utilization technology of biomass and coal is one of the eco-engineering process which can contribute to construction of sustainable society and prevention of the natural eco-system degradation in South East Asia. The development solar energy in sunbelt by means of hybrid utilization technology such as solar-hybrid fuel production system can be considered as one of the eco-engineering process, which will contribute to construction of sustainable society without destroying the natural eco-system. The creation of green market for utilization of the hybrid fuels will facilitate to solve the problem on the cost higher compared with that of fossil fules.

    The eco-engineering is discussed from the view point of realization of the sustainable society and creation of the new industry of [1+2+3] industry, which will be empirically proved in the community special zone. This new industrial system can be economically driven by the low cost fuel energy produced by hybridizing fossil fuels such as natural gas and coal with renewable energy of biomass (biomass-hybrid fuel). When this hybrid fuel is mainly used as a low cost fuel for production of the primary industry such as agriculture, forestry, stock raising, and fishery, the productivity in the 1st industry will be increased. This productivity can be further accelerated by introducing the green market for those products made by using biomass in the hybrid fuels. This system can progressively reduce the CO<sub>2</sub> emission by increasing the green market, because the renewable energy of the biomass can be increased.

    In this paper, solar-hybrid reforming of methane to produce hydrogen was proposed and investigated using a xenon lamp pseud-solar radiator. A mixture of methane and steam is introduced into a porous Ni catalyst heated directly by the solar energy passing through a quartz glass, and then, converted into product gases, i.e., hydrogen, carbon monoxide and carbon dioxide. The enthalpy of the product gas was recovered through a reciprocating-flow energy recirculation system using an inert porous ceramics that play a role of heat storage. As a result, it was shown that hydrogen including solar energy was produced quickly and effectively.

    In Part 1, a simulation system was developed to examine human spatial orientation in a virtual weightless state. By conducting experiments in several routes of connected modules, we found some relevant variables for spatial cognition errors. Part 2 clarifies the causes of spatial cognition errors by the similar experiments using more complicated routes. The results showed the errors were able to be explained by two causes. One cause was that subjects did not recognize the rotation of the frame of reference, especially more often when they turned in pitch direction rather than in yaw. The other cause was that subjects were incorrect in the place, the direction, and the sequence of turns.

    In a virtual weightless environment, pointing and modeling tasks were conducted to examine subjects'orientational skills. Subjects who wore a head-mounted display in a reclining chair moved from one end to the other end in several routes that were made by three or four modules that were connected by cubical modules, and pointed to the start point and made the experienced route by a scale model. Analyses of the results show the ability of spatial orientation varies with such variables as the number of bends, the number of embedding planes and the number of planes with respect to the body posture. Subjects who miss the tasks have a tendency not to take the change of the direction of their body axes into account.

    Cars represent an important mode of transportation for the elderly; however, in recent years, the number of traffic accidents caused by elderly drivers in Japan has increased. Thus, to ensure driving safety, we are researching a driver agent system that provides driving support and feedback support to elderly drivers to encourage them to improve their driving. In this paper, we report on a set of preliminary experiments using our agent in an actual car environment designed to evaluate the subjective acceptability of and distraction by the agent based on subjective evaluation and analysis of driver fixation points during driving. The results revealed that the acceptability of the agent was high and that the agent in an actual car environment did not distract the driver.

Thus, to ensure their driving safety, a system that can assist elderly drivers is required. In this study, we propose a driver agent system that provides support to elderly drivers during and after driving and encourages them to improve their driving. In this paper, we describe the proposed driver agent system. We conducted an experiment to evaluate driving behavior improvement through three types of support: driving support, review support, and a combination of both. The results revealed that the combination of both supports lead to the greatest improvements in driving behavior and was most acceptable to elderly drivers.

    In recent year, the number of traffic accidents caused by elderly drivers has increased. The effect of changes associated with aging in physical functions and cognitive functions is pointed out as one of the reasons. However, the car is one of important transportation for elderly. Therefore, the assistance measure to realize the safety driving for elderly drivers is needed. To overcome the problem, we are developing the agent that supports elderly drivers. The agent provides the advisement to elderly driver during driving a car and also encourages the driver to improve their driving behavior by showing their past driving records. In this paper, we described the analysis of human instructor's teaching model for considering the supporting method by the agent. From the analysis, we categorized the instructions into several groups and obtained findings about the impression of trainee caused by the instructions.

    To discuss the development of driving-assistance systems and enhancement of driving ability, we investigated stimulus-response behavior among elderly people by using the driving aptitude test. Participants were 100 drivers and were assigned to 3 groups based on age: 50s, 60s, and over 70. All participants provided informed consent and performed several cognitive tests and the driving aptitude test including 7 kinds of tests similar to those in the Lecture for Elderly Drivers in Japan. Analyses of response times and accuracy obtained from 4 of the 7 tests showed that participants in the 60s and over-70 groups delayed their responses when they were required to discriminate among various signals and respond using the foot pedal; and showed decreased performance under the blue-signal condition. The results helped determine elderly drivers’ stimulus-response behavior from the driving aptitude test data and indicated a factor-induced performance decrease during driving.

    <p>Although drivers’ driving habits have been investigated using self-report methods, some studies have reported inconsistency between self-reported driving exposure and actual driving data. Data on self-reported and objective driving exposure were collected from 66 drivers aged 50&#8211;83 years. Agreement between these measures was 0.07 and 0.03 for distance driven per day and number of days driven per week, respectively. Factors related to agreement between the two measures investigated, and the odds ratios computed by a binomial logistic analysis for gender and some attitudes (confidence to driving, hesitation about driving, and car as self-expression) were higher than those for other variables. Scores on these variables did not differ significantly between under- and over-estimated self-reports. These findings suggest that the direction of inconsistency between self-reported and objective driving exposure might involve different and general personality traits. Further, self-reported driving exposure may be affected to monitoring experiences brought by attitudes about driving.</p>

    <p>年々,交通事故件数・24時間死者数が減少する中で,65歳以上高齢者が占める死亡事故件数および死者数の割合は増加傾向である。これは,人口・免許保有者の高齢者の割合が増加したこと,つまり“社会の高齢化”に伴う現象である。高齢者は,衝撃耐性の低さから交通事故の被害リスクが高い。他方で,加齢に伴い,運転に求められる身体的構造,または身体機能や高次な認知機能等や運転技能が低下を示すことから,近年,高齢運転者の加害リスクも指摘されている。ところで「運転」は個人と社会をつなぐ重要な活動であり,個人の健康増進に寄与することから,長寿社会において,運転継続は個々人の幸福,QOLにつながる重要な人間活動と言える。多くの交通参加者が高齢者となる社会背景の中,社会はどうあるべきか,また,わたしたちはいかにあるべきだろうか?本シンポジウムでは,人間を中心に「人生100年時代」の交通安全社会の方向性を検討するため,「高齢者心理」「AIと安全運転評価」「運転と地域医療」「高齢者の免許と生活」「データを活用した健康・都市づくり」などをキーワードに,それぞれの専門家とともに横断的な議論を通して,模索したい。</p>

    Driver’s mental workload is not only a critical factor for road safety but also a challenging for the researcher to evaluate. This research introduces a novel of measuring the level of driver mental workload by using the difference between the predicted and observed eye movements. In this paper, the involuntary eye movement predicted based on the combination of the vestibule-ocular reflex model and the optokinetic response. By using n-back task to impose the mental workload for the driver, this hypothesis was validated and confirmed in a driving simulator as well as in a naturalistic situation.

    The purpose of this study is to understand the causes of accidents between cars and bicycles. We collected accident data from a drive recorder (DR) and compared them with near-misses to construct three models to determine the accident occurrences: (1) a kinematic model of accident occurrence based on the temporal relationship among time-to-collision, brake reaction time, and braking time; (2) a probability model based on logistic regression; and (3) a decision tree model that shows the hierarchical meanings of the variables.
    From driving simulator experiments, we found that the brake reaction time depends on the driver's eye position. The accidents were reconstructed for cars installing autonomous braking systems, showed that field of view of sensor was most effective in preventing accidents, and accidents that cannot be avoided even with ultimate AEB were identified.
