    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.

    <p>Through the once-in-a-century mobility revolution, the concept of mobility has changed from just the physical displacement of people and things to a huge network system that also includes the invisible exchange of information and energy. As changes occur in the surrounding demographics and environment, the mobility revolution has accelerated due to COVID-19. In this paper, we outline the impact of COVID-19 on mobility and discuss the direction of the mobility revolution, taking into consideration the mobility revolution as a whole and the social situation surrounding Japan.</p>

    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.

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.

    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%.

    &ensp;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.

    &ensp;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.

    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>

    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.

    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.

    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.

    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.

    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.

    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.

    本研究では四輪車対自転車衝突事故を対象として,事故とヒヤリハットのドライブレコーダ映像を比較し,事故の発生因子と閾値を求める.ドライビングシミュレータ実験から,衝突回避が困難な状況下の運転者行動を分析し,四輪運転者の行動モデルを作成する.このモデルを衝突の力学モデルと結合させて,統合事故再現データベースを構築する.データベースに衝突被害軽減ブレーキ等の衝突回避デバイスを導入し,事故における衝突回避効果を得る.さらに,この回避困難な衝突について有限要素解析を行い,自転車乗員の被害軽減の方策を得る.本研究では,事故発生から被害者保護までシームレスにつなぐ統合安全による自転車乗員保護方法を提示する.
    本研究ではドライブレコーダをもとに四輪車対自転車事故の発生要因を分析した.出会い頭事故が最も多いことから,この事故形態の分析を行った.映像から自転車乗員の位置や速度を求める方法を確立した.
    出会い頭事故では道路幅員が狭く,住宅等の建物が視界遮蔽物になっている無信号交差点で発生する場合が多い.四輪車自転車が見える時の衝突余裕時間TTCについて調べると,出会い頭の事故では2種類の類型が存在した.一つは,ドライバが自転車に気付くのが遅れ,ブレーキ反応も遅れたことによる事故であり,もう一つは,自転車の飛び出し事故である.四輪車が制動を開始した時点において,停止までに0.55G以上の減速度を必要とする領域に自転車乗員が入るかどうかで事故とヒヤリハットが区別される.
    ドライビングシミュレータによる被験者実験を行い,ドライブレコーダから確認された事故を再現した.TTCが大きなシナリオでは,被験者のブレーキ反応時間が衝突回避に大きな影響を及ぼす.TTCが小さなシナリオは被験者のブレーキ反応時間,TTC等が全て満たされたときに衝突回避が可能であった.
    ドライブレコーダ映像から事故再現を行い,さらに,衝突被害軽減ブレーキAEBを装備したときのシミュレーションをAEBのパラメータを変えて実施した.運転者の制動遅れに起因する出会い頭事故ではセンサー視野角FOVの拡大が有効であった.一方,自転車の飛び出しに起因するTTCが小さい出会い頭事故ではAEBによる衝突回避が困難であった.
    衝突時の自転車乗員の挙動について有限要素解析を行った.フロントピラーと頭部が衝突するとヘルメットを着用していても,頭蓋骨と脳実質には大きなひずみが発生し,重篤な傷害が予測された.衝突から路面落下までの挙動を明確にするために,車体から加わる力積および力積モーメントを用いて,人体の速度と回転を予測できることがわかった.
    本研究ではドライブレコーダによる四輪車自転車事故の事故映像を用いて,事故の発生要因を明確にし,その対策方法を提示することを目的とする.本研究の研究項目と進捗状況は下記のとおりである.
    1. 自転車乗員との衝突に至るパラメータを抽出するとともにその閾値を求める.さらに,衝突被害軽減ブレーキによる衝突防止効果を検討する.現在,出会い頭事故についてはほぼ研究を終了し,ヒヤリハットと事故を分ける因子,および事故の発生要因が明確となっている.さらに,次年度の予定であった右左折事故に取り組み始めている.
    2. ドライビングシミュレータによって実事故を再現して,ドライバ反応の分析を行い,事故の発生要因を運転者の行動の面から明確化する.今年度の目標であった出会い頭の自転車飛び出しにについては,ドライバ反応の概要が求められた.この反応が,ドライブレコーダによる事故でのドライバ応答とも一致していることを見出すなど,当初の予定を超える成果が得られた.
    3. 衝突時の自転車乗員の被害軽減のため,マルチボディおよび有限要素モデルを作成し,自転車乗員の挙動と頭部保護方法を検討する.これまでに,有限要素モデルから自転車乗員が衝突時に受ける衝撃と傷害の予測が可能となった.本年度の目標としていた直接の傷害リスクの評価に加えて,路面による傷害を検討するめどがたつなど,予想を超える進展があった..
    以上のように,現在,研究計画を超える進捗が得られている.
    ドライブレコーダによる四輪車自転車事故の事故映像による事故の発生要因の明確化,その対策方法の提示をさらに進めるため,つぎの研究項目を下記の手順で進めていく.
    1. 出会い頭事故に加えて,事故発生頻度の高い右左折事故について,自転車乗員との衝突に至るパラメータを抽出するとともにその閾値を求める.右左折事故については,ドライバと自転車乗員の予測の誤り,「Looked-but-failed-to-see」などの問題が関与している可能性があり,ドライバと自転車乗員の顔映像を見ながら事故発生要因の統計分析を進める.さらに,右左折事故では衝突被害軽減ブレーキに加えて,ドライバウォーニングよる衝突防止効果を検討する.
    2. ドライビングシミュレータによる実事故を再現によるドライバ反応の分析をさらに進める.昨年の実験結果の統計分析から,年齢が高いほど,慎重な運転を行うために事故が起きにくいという結果が得られている.さらに後期高齢者も含めた実験を行い,年齢とドライバ反応の関係につて研究を進める.また,右左折についてもドライビングシミュレータ実験を試みる.
    3. 四輪車衝突時の自転車乗員の被害軽減のため,これまでに,作成したマルチボディおよび有限要素モデルによる計算を進め,自転車乗員が四輪車と衝突して以降,路面に衝突するまでの一連の過程での傷害防止対策を検討する.特に,現在,対策が困難とされている路面衝突について,挙動のコントロール方法を検討する.
    4. 自転車衝突における四輪車ドライバへのウォーニング,衝突被害軽減ブレーキ,自転車乗員のヘルメット着用,衝突時の自転車乗員の挙動コントロールを組み合わせた,「統合安全」の効果の見積もり方法について検討する.
