<p>In recent years, shared taxis have been attracting attention in Japan. From October 1, 2020, Arao’s “Omoyai Taxi”, which is a substantial “shared taxi”, started operation. However, there is not enough consideration on the service setting of shared taxis and the appropriate setting of the number of vehicles in rural areas. In this study, we conducted two surveys those are house hold travel survey and stated preference survey for ride-sharing taxi to estimate a conversion model. Sensitivity analysis is performed using an operational simulation model connecting K-MATSim with SAVS by Web-API. A comparative analysis is performed between the predicted value by the operation simulation and the actual usage. Finally, the purpose is to update the conversion model.</p>

<p> Due to the surrendering driving licenses of private of the elderly and the decline in walking ability on slopes, they decrease the opportunities for daily travel, which tends to lead to a decrease in QOL. In this study, we worked on the creation of an "personal mobility plan" for New Town residents, whose elderly population is increasing. The "personal mobility plan" is intended to be linked with an com-prehensive community care plan, and carefully grasps various characteristics of users such as home loca-tion, fami-ly structure, physical condition, and mobility demand, as well as individuality. In this paper, we report on the social demonstration experiment conducted in Kozoji New Town, and summarize the issues of the " personal mobility plan " from the results of user monitor creation and the results of the question-naire.</p>

<p>In this study, we have built an advanced simulation system that links an agent-based meso-traffic simulator and an on-demand matching system in a computer to evaluate impacts of ride sharing taxi service. This system was implemented for a central area of Kumamoto city to verify the effect of introducing this service. As a result, by increasing the number of shared vehicles, the time required for the user to arrive at the destination was significantly reduced, but the operating rate of the vehicles decreased. From these results, the demand in each time zone was predicted, and it was suggested that it is necessary to adjust the number of vehicles dispatched to demands and the operation area.</p>

<p>In this study, we evaluate the effect of introducing MaaS by simulation using a multi-agent traffic simulator and cost-benefit analysis. As a case study, we use the MaaS demonstration experiment conducted in Shizuoka City in November 2019. In this demonstration experiment, in addition to railroads and fixed-route buses, the on-demand shared service, SAVS (Smart Access Vehicle Service), was introduced. We model users' mode choice behavior (demand side) and use vehicle allocation optimization method of SAVS (supply side), and integrate demand and supply model with traffic simulator SUMO to model demand-supply interaction. In order to quantitativel yevaluate the impact, we define a various indicators from different standpoints (users, providers, city, etc.) accordingto the cost-benefit analysis approach. Analyzing results show that the introduction of MaaS did not produce cost-effective benefit. However, exhaustive simulation revealed that the MaaS service can be established if the number of SAVS vehicles and price are set appropriately.</p>

<p>To solve the increasing urban congestion problem, intelligent transportation system (ITS) is drawing researchers’ attention. Dynamic traffic assignment (DTA) has been recognized as a significant part of ITS solutions for a long time. Most DTA approaches focused on realizing single objectives by solving routing problems but paid less attention to the intersection which is the main bottleneck of urban networks. This paper proposes a method based on the link transmission model (LTM), which manages the traffic flow of each incoming link at the intersection, to reduce the congestion when route choices are determined in advance. This method employs a local linear programming formulation so it can be added to other DTA approaches which have different global objectives. The proposed model and other LTM-based models are tested by simulation data. Results show that the congestion level in the proposed model is lower than other models, while the travel cost remains similar.</p>

Several companies provide an aggregated data on people's travel. "Mobile Spatial Statistics" is, for example, the estimation results of staying population from the number of cell-phone users that counted at each base-station. Although this data include both travelers and staying people (e.g., people working at same location), it can be gathered at arbitrary location and in any time-zone. In this study, we propose a novel estimation method for multi-mode origin-destination flows, which is an important information in transportation planning, from "Mobile Spatial Statistics" and the other traffic counting data (i.e., the number of train or bus passengers and GPS trajectory data), and applied to the Hakodate City.

In the system, the locations and routes of all vehicles are controlled by a computer, and no fixed routes or time-tables are necessary. We call it “transportation cloud”. The system responds to new demands in real time and provides utility of taxis with cost efficiency of buses. Furthermore, it can flexibly readjust to traffic congestion, accidents, malicious weather and disasters. We conducted operation tests and succeeded in running the system automatically for several days.

In most urban area, traffic issue related to parking (e.g. economic (time) and environmental loss in finding a parking space) has been significant, and parking management strategies to set optimal price are often necessary for the parking agencies. In order to revise parking fee appropriately without a reduction of parking demand, a pricing procedure in accordance with characteristic of parking utilization is expected. On the other hand, a large amount of parking data is accumulated automatically with introduction of online parking systems. In this study, we analyze massive parking accounting data, whose data size is 22.5 million accounting data in the past year about 1,050 parking lots, and discuss the characteristics of parking utilization. Moreover parking duration model is developed from the accounting data for each cluster to estimate the parking demand (i.e., parking time) after changing price. As an example of appropriate price procedure, we evaluate the setting of an upper limitation of parking charge with parking demand patterns calculated from the accounting data and the parking duration model.

Parking management has attracted attention as an effective transportation policy. Although many studies analyzing parking lot choice behaviors have been conducted, most of them utilized data gathered by one-shot questionnaire surveys. Currently, in Japan, it is possible to easily observe parking lot choice behaviors over long time periods since online parking accounting machines have been introduced at many parking lots. In order to analyze and model the parking lot choice behaviors, we utilized massive parking accounting data including membership identification data. From the results of a basic analysis targeted at nine parking lots in Nagoya, we found that users rationally chose different parking lots according to their parking time, and some high-frequency users preferred to choose the same parking lot, indicating a similarity to habitual behavior. Moreover, we compared the characteristics of parking lot choice behaviors between high-frequency users and others by developing a parking lot choice model.

In this paper, we propose a dynamic route-exchanging mechanism based on anticipatory stigmergy and demonstrate its efficiency. Next-generation traffic management systems based on probe vehicle data have been attracting attention. Ito et al.[2] [3] [4] previously proposed a traffic management method based on anticipatory stigmergy that can search for an alternative route to avoid expected congestion by sharing the probe vehicles’ expected locations in the near future, and they found that anticipatory stigmergy works well in particular experimental settings. On the other hand, Takahashi et al[6] identified two key issues: (1) The oscillation of congestion occurs because drivers do not know other drivers’ decision making. This problem is well-known as the El Farol Bar Problem or the congestion game. (2) The saturation level of navigation systems could affect the performance of a dynamic route exchanging-mechanism. In this paper, we propose a new dynamic route-exchanging mechanism that can address the above two issues. In the basic procedure, each vehicle submits its intention about its near-future position (60 seconds). Then the traffic management center computes the near-future congestion information for each link. This information is anticipatory stigmergy. If there is an over-congested link after 60 seconds, the vehicles assumed to come to those links are allowed to negotiate with each other so that some of them will change their near-future routes. In this mechanism, vehicles automatically negotiate based on their rational judgment on the trade-off between travel time needed for passing the assigned route and the ”concession coefficient” that represents how a driver can concede the way. The experimental results demonstrate that our new route-exchanging mechanism performs well for the efficiency of traffic flow when the saturation level of probe vehicles is greater than 70%.

This study proposes the modified stochastic cell transmission model (M-SCTM), which can be used to apply the conventional SCTM to urban networks. Although SCTM can represent an uncertainty of traffic state and changing travel demand or supply conditions, it has been applied to a freeway or a simple network that has only one origin-destination pair. In M-SCTM, we introduce vehicle agents and their route choice behavior on an urban network for application to more complex urban networks. From the results of an empirical study, we confirm the reproducibility of travel time that are calculated by M-SCTM.

As carsharing services have been expanded by private business operators, this study analyzes carsharing users' behavior in the Nagoya metropolitan area. Using data provided by a carsharing operator, this study reveals the purpose of use by tracking the GPS trajectory and the typical use pattern by cluster analysis. Also considering the regional characteristics, a decision tree model focusing on the discriminant the use purpose was devised. Results show that the use pattern is different between men and women, and that users tend to make a reservation right before use. Furthermore, carsharing is most often used for personal affairs like shopping or leisure.

As parking accounting data of automatic payment system is accumulated, a managing parking fees in accordance with characteristics of parking utilization is expected. The purpose of this paper is to analyze the characteristics of parking utilization from a big data and to propose a procedure of parking fee management by developing of a simple simulator from a history of parking utilization. In concrete terms, we classify 1,050 parking lots by cluster analysis and analyze influence of a charge revision on parking time by survival analysis from 22.5 million parking accounting data in the past year. Further, we consider the appropriateness of modified fee by estimating parking time with a hazard-based duration model.

This study proposes the modified stochastic cell transmission model (M-SCTM), which can be used to apply the conventional SCTM to urban networks. Although SCTM can represent an uncertainty of traffic state and changing travel demand or supply conditions, it has been applied to a freeway or a simple network that has only one origindestination pair. In M-SCTM, we introduce vehicle agents and their route choice behavior on an urban network for application to more complex urban networks. From the results of an empirical study, we confirm the reproducibility of traffic volume and travel time that are calculated by M-SCTM.

In this study, we examine the impacts that electric vehicles (EVs) have on vehicle usage patterns and environmental improvements, using our inte-grated travel demand forecasting model, which can simulate an individual activity-travel behavior in each time period, as well as consider an induced demand by decreasing travel cost. In order to examine the effects that charging/discharging have on the demand in electricity, we analyze scenar-ios based on the simulation results of the EVs' parking location, parking duration and the battery state of charge. From the simulation results under the ownership rate of EVs in the Na-goya metropolitan area in 2020 is about 6%, it turns out that the total CO2 emissions have decreased by 4% although the situation of urban transport is not changed. After calculating the electricity demand in each zone using architectural area and basic units of hourly power consumption, we evalu-ate the effect to decrease the peak load by Vehicle-to-Grid (V2G). Accord-ing to the results, if EV drivers charge at home during the night and dis-charge at work during the day, the electricity demand in Nagoya city increases by approximately 1%, although changes in each individual zone range from-7% to +8%, depending on its characteristics.

Commuters' returning home behavior at disaster in Chukyo metropolitan area is investigated by using traffic simulation. Disaster prevention manual by the Government suggests to return home on foot, but it is expected that many people are unable to walk home because of long distance to home as in Tokyo metropolitan area. Car share in Chukyo area is higher than that in Tokyo area, so the effect of car use should be more carefully considered in the former area. The objective of this study is to explore the effect of the car use by simulating the traffic conditions when the car use is allowed at the disaster. The estimation results suggest that more people can return home if the car use is allowed but it causes a severe traffic jam potentially preventing rescue traffic.

Road pricing has been recognized as the most efficient policy to reduce traffic congestion and pollution. In order to implement this policy in practice, it has been important to allocate the revenue from the view point of equity and acceptability. This study examines the revenue redistribution effects of a normal prcing and parking-deposit-system from the aspects of traffic situation, efficiency and equity. We formulated the bi-level optimization problem which consists of a social surplus maximization model and a multiclass combined equilibrium model that can treat a difference of time of value. According to the application results in Nagoya metropolitan area, efficiency and equity are improved if the expressway toll and the train fare are discounted as the revenue redistribution, and its ratio is different in each pricing scheme.

Consensus building toward the introduction of LRT has often run into trouble since there are difficulties to quantitatively measure the effects such as modal shift from overdependence on automobile, reduction of environmental loads, vitalization in CBD and the improvement of urban landscape. This paper applied an integrated travel demand forecasting model in order to evaluate the impact on the central city invigoration by the introduction of LRT as well as the change of traffic conditions. As a result of application to the Nagoya metropolitan area, it was calculated that LRT would reduce the car usage in the CBD while it induce the trips by bicycle or walking. Also shown was that the number of visiting spots and the duration spent in the CBD would increase, implying that the introduction of LRT could be contributed to the vitalization in city center.

A survey by questionnaire was conducted to study the frequency and range of movement of residents in Niyodogawa-cho, Kochi Prefecture, located in a mountainous region. The result is classified by age group. It is confirmed that the frequency and the range of activities differ by age group: the higher the age, the lower the frequency. It is predicted from the results that the situation rapidly changes in a rapidly aging mountainous region. This prediction is required to be considered for planning of development and maintenance of infrastructure.

This paper takes advantage of a GA based Bi-Level Programming Problem to find the optimal scheme of second-best road pricing problem, the method optimizes locations and toll levels simultaneously. The highlight of this paper is that the case study was taken on the actual network of Nagoya Metropolitan Area instead of a numeral network, in order to evaluate the effect of the method, we made comparison between a cordon pricing scheme and the same number of links tolled optimal locations and toll levels schemes. The result showed that under the situation of the same number of links, the optimal locations and toll levels scheme works better than the cordon pricing one.

Parking Deposit System (PDS) is proposed to improve public acceptance of Road Pricing (RP) which can reduce effectively traffic congestion and air pollution. This study examines the characteristics of PDS and conventional RP (cordon-based and area-based pricing) in terms of efficiency and equity. In order to evaluate income regressive effects as equity, we construct a multi-class network equilibrium model of the user's mode and route choice behaviors for the several income classes. As a result of application to the Nagoya Metropolitan Area, PDS has the following characteristics as compared with conventional RP. 1) PDS has sufficient environmental improvement effect, although the car reduction effect becomes small by refund. 2) In area-based pricing, the efficiency of PDS is higher than the conventional system. 3) PDS is more equitable system because it is a kind of revenue allocation policy.

This paper proposes an integrated travel demand forecasting model for a formulation of comprehensive transport strategy and validates its usefulness as a practical tool. In order to overcome and/or modify some drawbacks of Four-Step forecasting model, we develop a semi-dynamic combined network equilibrium model including an activity-travel model that consists of activity choice, destination choice, mode choice and route choice, and also reproduces a trip chain along the time axis by a sequential computation. From the application results of an actual metropolitan area, it was demonstrated that our model is useful from the both of reproducibility and computational efficiency.

This study analyzes the effect of road pricing using a model with the following characteristics: 1) integration of trip generation (i.e. activity choice), destination choice, mode choice and route choice; 2) consideration of hourly traffic condition variations including queue evolution; and 3) approximate reproduction of trip chain along the time axis. An evaluation of road pricing in the Nagoya Metropolitan Area shows that pricing leads to an effective improvement in the environment as a result of a reduced number of car trips, and at the same time, there is a great reduction in the number of visitors because there is a change of destination and only a small shift to railway.

This paper examines an applicability of the traffic assignment model overcoming some drawbacks of conventional models. The developed model has the following characteristics: 1) integration of trip generation (i.e. activity choice), destination choice, mode choice and route choice; 2) expression of traveler's choice behavior as a nested logit structure; 3) consideration of hourly traffic condition variations including queue evolution; and 4) approximate reproduction of trip chain along the time axis. The reproducibility of developed model is shown under application to the Nagoya Metropolitan Area, Japan. Furthermore, as case study, we evaluate road pricing and railway's fare discount. These results suggest that the model allows us to compare various TDM policies effectively and evaluate in detail.

Disaggregate model can take into account individual travel behaviors in detail, but in forecasting a case of improving service level of transport networks, the changes in service level of automobile are not often considered. On the other hand, combined stochastic user equilibrium model always considers the changes appropriately. In this study, we apply these two models to the Nagoya metropolitan area in order to verify the difference of prediction results. As compared with the equilibrium model, disaggregate model brings the results that the number of automobile trips is overestimated and one of railway trips is underestimated, although the total number of generated trips and the share of each trip purpose are not so different. Especially, the difference is large in short-distance and middle-distance trips.

It is difficult to evaluate TDM policies by the Four-Step forecasting model because this model presents some significant drawbacks.“Semi-dynamic Combined Equilibrium Model considering Activity choices” is one of models which can overcome and/or modify those problems. Our model integrates trip generation, destination choice, mode choice and route choice behavior, and considers the time-axis and the remnants of flows. Thus we can not only measure induced traffic but also analyze in trip-chain approach. Our model is valid according to the reproducibility applied to the Nagoya Metropolitan Area, although it is necessary to improve the calculation efficiency.

Recently, the development of the model that express real traffic flow from hour to hour accurately is required. So, this study analyzes the traffic prediction of Nagoya City in the morning peak hours by using the road network including expressway in Nagoya City and suburb of it. Expressway in the network have many features unlike ordinary road, therefore it needs some countermeasures. In this study toll is converted by value of time as the way of dealing with it in the time. In addition, conversion rate of expressway uses as a method. The purpose of study is to examine about the present state reapperance of the model.

The aim of this study is to examine about the hourly traffic assignment method when the user equilibrium model is applied to the road network including expressway. The toll road including expressway have a lot of features unlike the surface street. For example, the running speed is faster, the capacity of the road is larger and toll is necessary. So we cannot treat it like the surface street equally without some process. In this study, the toll resistance method (toll is converted by time value) and the diversion rate method for the expressway are used as the way of dealing with this problem. Well, this study analyzes the traffic prediction of Nagoya City in the morning peak hours by using the road network around the Nagoya City, and compares two methods. According to the assignment results, the time value is 60.5 yen/person/minute by the toll resistance method, and 40.0 yen/person/minute by the diversion rate method for the expressway. According to the questionnaire investigation, the time value is 62.5 yen/person/minute. So the result of the toll resistance method is close to that of the questionnaire investigation.
