     View Summary

    In recent years, social changes have accelerated due to the advancement of technology and the promotion of diverse work styles. In light of these circumstances, it is necessary to consider the aggregate amount of human behavior using the four-step estimation method as in the past and understand the behavioral characteristics of individuals and consider the actual situation in society. In this study, we proposed an estimation method that enables more accurate policy evaluation and demand forecasting at a lower cost, using activity simulations that can reproduce an individual's daily activities and take into account the linkage of trips, and observation data of traffic conditions, the types and amount of which have increased dramatically in recent years. By applying this method to the Tokyo metropolitan area, the forecasting accuracy was improved and the usefulness of supplementing observation data to activity simulation was confirmed.

    Journal of the City Planning Institute of Japan   56 ( 3 ) 834 - 841  2021.10  [Refereed]

     View Summary

    During the COVID-19 pandemic, decreasing human mobility remains an essential measure despite the start of vaccinations due to the disease’s long incubation period and high infectivity. This study aims to investigate the effects of the 1st state of emergency, prefectural state of emergency, and 2nd state of emergency on human mobility during the COVID-19 pandemic based on the mobile spatial statistics and the pedestrian count data by applying the Bayesian structural time series model. First, we quantified the effects of different states of emergency regarding both under and after the declaration. Second, comparing the two data sets shows that the staying time reduced after the 1st state of emergency even though the number of pedestrians recovered the previous level. Third, the changes in human mobility consistent with the existing surveys on remote work and behaviors during the COVID-19 pandemic.

     View Summary

    In this study, we conducted an interview survey and a message effect verification experiment using a cognitive function test in order to verify the effects and side effects of the psychological effects of the cognitive test on examinees.
    As a result of the interview survey, most people said, “It was difficult.” after doing cognitive test regardless of the results. And someone compared with the past results. As a result of the message effect verification experiment by the cognitive test, those classified as (iii) had significantly lower values in 4 scales behavioral intention of car use reduction / license return after the test. These results indicate that the expected side effect was indeed in play. Those classified as (ii) had a significantly higher intention to return their driver's license after the test. From the above, the cognitive test had both a main effect and a side effect.

  • A Study on Applicability of State Space Model for Grasping the Effect of Measures of Expressway

    Masakazu Nakanishi, Masato Maeda, Takashi Kodama, Kuniaki Sasaki

    Journal of JSTE   6 ( 1 )  2020.02  [Refereed]

     View Summary

    The effects of events that affect road traffic, such as new opening of expressways and toll changes, are generally grasped by comparing before and after indicators such as traffic volume and loss of time. However, there is a possibility that the change in the effect cannot be clearly grasped due to the influence of different day arrangements or the influence of incidents. On the other hand, past studies apply a state space model to traffic volume observed in time series, and classify them into long-term fluctuations, periodic fluctuations, and short-term fluctuations, and analyze traffic characteristics. Therefore, in this paper, we apply the method shown in previous studies, such as classifying the traffic volume observed in time series into each fluctuation component for the traffic situation observed on the Hanshin Expressway. In addition, we will try to clarify the effects of new expressways opening and toll change by grasping long-term fluctuations. We also consider the applicability of the method in practice.

    Kuniaki Sasaki

    Journal of the City Planning Institute of Japan   52 ( 3 ) 849 - 855  2017.10  [Refereed]

     View Summary

    This study focused on the effects of transportation environment of community on the exercise frequency, subjective health condition and subjective well-being. We adopted accessibility as the transportation environment. The accessibility is evaluated by public transport and automobile to three types of purpose. The variable of the exercise frequency, subjective health condition and subjective well-being were collected by the questionnaire survey. We used logistic regression for the analysis of relationship between the variables, which consider the difference of the community by the multilevel analysis. The result shows the accessibility of medical facilities by public transport and by car is significant on the health condition and frequency of going out, respectively. This result implies that the improvement of the accessibility by public transport and by car may affect the health condition of the community.

    Journal of the City Planning Institute of Japan   52 ( 3 ) 1262 - 1267  2017.10  [Refereed]

     View Summary

    The SA/PAs on expressway are required to offer not only traditional rest stop services but also attractiveness of tourism destination as well as additional services, such as refreshments, dining options, and souvenir shopping. It is clear that these marketing strategies furthermore should take diversification of tourist's decision structure patterns underlying stopover behaviors at SA/PAs into consideration. The latent class analysis is applied to driver's behavior pattern data on Chugoku Expressway. The LCA models aims to represent how the drivers conditioned by those latent classes choose the location of SA/PA using the observed variables. The developed LCA models with covariate variables indicate an effective tool of market segmentation of these SA/PA stopover behavior patterns.

     View Summary

    Managing the cost of the long term care service is critically important to provide the better service to the aged people in the hyper-aged society. In such management, we need to be sensitive in keeping the necessary services in cutting the cost. Therefore, identifying what determines the aged people's service user is necessary. Mobility would be one of the keys to the decision making in choosing the service, because most of the nursing care service is related to the transportation: Nursing service offers not only facility care services but home nursing care including shopping assistance. In this study, we investigated the relationship between the transportation environment and the use of the service. We focused on those who do not use nursing service, despite the certification of the long-term care, in order to find why they do not use. We analyzed what led one to use or not use the nursing care service by using multilevel logistic regression analysis, because it allowed us to consider the difference of the error structure. We applied the model to the data of a local city in Japan. The result shows that some variables indicating accessibility significantly affected one's decision whether one uses the service or not. The accessibilities of car to clinic, hospital and neighborhood shops significantly affected the decision, while only the accessibility to the hospital was significant when one uses public transport. More than 50 percent of the aged people use motorcars to travel in this city, and this might be why more number of the accessibility by using the car significantly affected the nursing service use. We might be able to manage the cost of service use more effectively and efficiently through the accessibility improvement. use. We might be able to manage the cost of service use more effectively and efficiently through the accessibility improvement. (C) 2017 The Authors. Published by Elsevier B.V.

    The time series of travel time variation of highway can be observed easily by ICT devices such as ETC transaction record. This study focused on the travel time variation of a highway where the traffic congestion frequently occurs. This study assumes the cyclic fluctuation is stationary, then we analyzed the residuals of the travel time model. The travel time variation is modeled by ARMA process and the residuals are analyzed by the GARCH model. We proposed to use volatility as one index of travel time reliability and showed the variation of volatility during four years graphically. From that result, we show the characteristics of transition of the index.

  • Sustainable market design for short-trip rideshares: simulation based on one- to- one two-sided matching with informational guidance.

    YOTSUTSUJI Hirofumi, SASAKI Kuniaki, MARUYAMA Mitsuho

    Asian transport Studies   4 ( 1 ) 278 - 294  2016  [Refereed]

     View Summary

    In this study, we focused on a short-trip rideshare system including nonmonetary rewards supported by other-regarding preferences of altruistic drivers in a village community. A methodology for simulating various mechanism designs of the short-trip rideshare system was developed. Using numerical simulation, we studied ways to improve the sustainability of the system by providing informational guidance. As a result, we showed that a higher number of rideshare pairs were sustained by messages that shaped the expectations of driver candidates about the success of ridesharing. From our numerical example, we concluded that the conveyance of informational guidance by a system operator, which induced each driver candidate to take action towards their delayed matching in place of failure, was reasonable roughly three times out of ten to promote system sustainability from the perspective of both the number of rideshare pairs and the welfare level of all participants.

    This study focused on modeling the indexes of individual built environment and their effects on the subjective evaluation of the life. The life satisfaction is regarded as the stable index for measuring happiness in the past researches in this decade. Thus we adopted it as the main subjective index in this study. The indexes of built environment of individual were measured as the number of available alternatives and the experience of activity abandoning, based on the idea of capability theory. The empirical study used the data collected in the mountain area. We found that the life satisfaction is not directly related with the number of alternatives but the experience of activity abandoning trip which means the margin of the capability is related.

    About 1.3 million lose their life worldwide, and this is set to double by 2030 if status quo continues. It is the developing countries which account for overwhelming part of the current fatalities, and forecasted accident fatalities. There are local as well global initiatives to address the safety issues, in developing countries in particular. However, there are emerging issues in developing countries that may result in safety trend different from that of industrialized countries. This has huge policy implication as it may make innovative measures inevitable. Therefore, to address the safety issues effectively it is necessary to grasp its nature and trend in developing countries. This paper analyses the dynamics in traffic accident trend in Asian countries, re-evaluates the current traffic safety approaches for strategic policy recommendations for emerging trends in the region.

     View Summary

    Abstract: In regions of Japan, in small, low-density communities that have inadequate public transport services, the lack of support systems for persons of limited mobility is emerging as a social issue. To complement this, this study focuses on volunteer-based dynamic ridesharing. In this paper, the feasibility of ridesharing is analyzed by pre-survey data and the availability is examined through a field experiment. The pre-survey showed that the field suited the ridesharing experiment, due to some results of a proper proportion between demanders and suppliers for rideshare, and a synchronicity of trip destinations and travel times, etc.. The experiment, however, revealed issues such as worry and hesitation of volunteer-based suppliers who have no opportunity to match other demanders except stable-matching pairs, incentives for their participation and their reservation, and sudden cancellation of the suppliers at the matching locations after their reservations. This paper describes improvements of the proposed ridesharing system.

    TRANSPORTATION RESEARCH RECORD   ( 2285 ) 119 - 125  2012  [Refereed]

     View Summary

    The data on how travelers evaluate a specific sightseeing destination are useful for formulating tourism strategies. Making a survey is the most common way to get such data now, but the method has become difficult because travelers have become so diverse that the data are not as meaningful and substantial as they had been. To overcome this problem, Internet blogs are used: comments on sightseeing are so popular that it is easy to collect the needed data. Blog data on tourism were collected in Yatsugatake, Japan, and compared with the data obtained from ordinary questionnaire surveys to examine the features of blog data. Information from 192 blogs was collected. Analyzing the terminology used in the blogs allowed the determination of some attributes of their authors. These attributes were compared with those of questionnaire survey respondents. Although the desired information can be obtained from survey respondents, information from blogs depends on what the authors write about any destination. Nonetheless, because a blogger's destination is clear in his or her blog, the information about destinations can be used by co-occurrence analysis. With categorization of the entry tags of each blog, information about each blogger's interests can be obtained, and their preferences clearly indicate that their destination choices are closely related to their interests. In sum, although the information in blogs is subjective, if used properly the information can be effective in developing strategies for tourism by complementing data from ordinary surveys.

     View Summary

    The shift of travel demand policies from the conventional supply oriented policies to management oriented policies has made the effectiveness of conventional trip-based modeling approaches, which still dominates the practice, questionable. In addition to this, the increasing finical burden of the conventional PT-surveying is making the sustainability of the model doubtful. The attempts so far to reduce the cost mainly focused on finding alternative surveying methods and techniques. In this paper, however, we investigate how shifting to alternative models, tour-based model in this case, may contribute in reducing the cost burden of the conventional PT-surveying approach. We will also investigate future prospect of this approach.

    KSCE JOURNAL OF CIVIL ENGINEERING   14 ( 2 ) 221 - 230  2010.03  [Refereed]

     View Summary

    The shift of travel demand policies from the conventional supply oriented policies to management oriented policies has made the effectiveness of conventional models questionable. However, although the new generation travel demand models have theoretically appealing backgrounds, they have so far failed to fully attract the practitioners to apply them for practical purposes. Lack at proper understanding and wrong perceptions of the new generation models have contributed to the gap between research and practice. This paper suggests a way to incorporate the features of new generation models using ordinary PT (person trip) data, to get an optimum model. Based on this, we propose a model that captures the link among travel decisions of a day as a travel pattern. We also illustrate the practical advantages of the new generation models, comparing with conventional models, in evaluating policies by an empirical study.

    Kuniaki Sasaki, Kazuo Nishii

    TRANSPORTATION RESEARCH PART C-EMERGING TECHNOLOGIES   18 ( 1 ) 36 - 44  2010.02  [Refereed]

     View Summary

    Mobility, one of the key concepts to evaluate the effect of a transportation policy such as TDM and mobility management as well as to analyze the problems such as social exclusion, must be measured by how much of an intention to make a trip can be realized, not merely by how many trips are available. The advent of new communication tools such as the Internet and mobile phones has allowed one to accomplish certain tasks that previously required a trip. This new situation has brought up a discussion over the necessity to incorporate telecommunications as an aspect of mobility. Aware of such discussions, we analyzed the relationship between the number of trips and telecommunications based on the data we collected on trips, telecommunications, and activities, and found some significant correlations. Our study which used an ordered regression model found several significant relationships between the individual attributes and the number of trips/telecommunications. We formulated a model which assumes the latent factors among the trips and telecommunications. In addition, we found that the latent factors construable as intentions to trips and telecommunications could be measured better by e-mails than by trips. These results indicate that measuring mobility requires the inclusion of information about telecommunications. (C) 2009 Elsevier Ltd. All rights reserved.

    While tourist has a variety of needs to get information and make a decision about their excursions in sightseeing areas, it becomes one of important subjects to identify the causal relationship between their excursion patterns and the obtained information. The relationship of information usage and excursion behavior was confirmed by using the structural equation model: information usage at the scheduling stage has an impact on tourist individual's Cognition for the sightseeing area, tourist individual's Cognition affects information usage at excursion stage, information usage at the excursion stage affect behavior of excursion. Therefore, modeling of the excursion behavior should consider the relationships mentioned above.

    The purpose of this paper is to analyze the effect of the information uses on excursion activity patterns. The survey are conducted at the different types of sightseeing area: Fuji-Five Lakes area and Arashiyama area. First, two data sets from these surveys are empirically used for a comparative analysis to identify the basic characteristics of excursion patterns. Second, focusing on the Fuji-Five Lakes area data set the information use patterns by excursion pattern are analyzed by using the concept of timespace prism. Finally, the duration model for Kyoto-Arashiyama excursion behaviors is developed to evaluate the effect f the information use on the length of time-duration at a stop in a chain. This model indicates that the information uses significantly determine the parameters concerning the duration-time distribution.

    In this study, our purpose is to identify a causal relationship in receptivity relating to the public involvement for current road improvement projects in Korea. Some of hypotheses about causal relationships among the psychological factors are assumed to develop a structural equation model. This model includes latent variables determining the receptivity relating to public involvement procedure, such as distrust feeling for administration (public sector), the knowledge and satisfaction about the road project, and the comprehensive faculty on the public involvement. The estimated model indicates that these assumed hypotheses are proved and that the administrative distrust strongly determines the receptivity as well as understanding of the road project and the knowledge of PI procedure.

    The focus of this study is in two points. One is constructing a simulation model of tourists' excursion behavior considering scheduling. The other is proposal of an evaluation method for the activity simulation model. To explain the characteristics of the touring behavior, a model of activity sequence was developed. In this model, it is assumed that tourists choose a combination of visit areas and then select the first and the last spot independently. We developed a simulation model for whole tourist behavior using other several models and showed its result. We also develop an evaluation indicator for the model system. This indicator is based on the reenactment of activity patterns. We concluded the model system we proposed could simulate the behavior well under a specific situation.

     View Summary

    This paper aims to develop a model of location preference of manufacturing industry companies in response to the change in level of service of travel time caused by highway construction. Two types of location choice model are proposed: One is a Logit type model directly incorporating a function decreased by distance. The other is a Dogit type model that represents the area-specific component determined by this distance function. The results show that the estimated parameters for both of two models are statistically significant, while hit ratios are not enough. They also suggest that, as the correlation coefficients between land price and the estimated area attractiveness are not insignificant, the area attractiveness have relations with the potential of the areas.

     View Summary

    This study proposes a new urban-travel demand forecasting system based on a micro-simulation approach as an alternative method to four-step estimation methods. This system comprises, 1) PCATS which simulates an individual's daily activity-travel pattern, 2) DEBNetS which simulates vehicle trips on urban road network, 3) a household simulator which generates future household attributes, and 4) a system to evaluate inter-zonal travel times and costs by public transit based on public transport networks and time tables. The system was applied to replicate the travel demand in a 1990 travel survey data set. A comparison between the observed and the forecast indicated that the system is capable of producing reasonable forecasts.

     View Summary

    This Study is focused on the structural heterogeneity of perception. We adopt LISREL type model to calibrate perception structure and use the actual choice as the indicator of the heterogeneity. First, we segmented the population by actual choice. Next we modeled cognitive dissonance effect introducing the choice indicator into the measurement equation. The inertia effect is also tested by introducing the choice indicator into structural equation. In the case study of choice modeling with latent variables, the inertia effect model improve the fit measure more than the other model.

     View Summary

    The objective of this research is to find factors that affect our recreational behavior by using disaggregate models for such trips. More specifically, a discrete-continuous model is proposed to explain the choice of the number of days spent for recreational trips in a year and the type of the trips. The model is applied to the national survey of recreational behavior to find that regional economic and recreational resources substantially affect the behavior.

     View Summary

    This research proposes a methodology to quantitatively evaluate the impact of traveler's pre-trip information considering transaction cost for travel behavior changes. The transaction cost is defined as the difference of expected utilities which are observed before and after travel behavior changes, and is estimated using a discrete choice model which represents mode choice behavior with and without the information on travel time respectively. The model is estimated with mode choice RP data and SP data for hypothetical information provision. Furthermore, we empirically analyze the impact of pre-trip information provision to enhance new transportation services such as Park and Ride.

     View Summary

    The purpose of this study is investigating efficient methods incorprating the heterogeneity of individual into the travel mode choice models. In this study, we propose two different market-segmentation approaches. One approach is a market segmentation by individual specific estimates obtained from a number of SP data of an individual. Another is a market segmentation by latent attitudinal variables. Then we applied these proposed methods to the mode choice SP data setting up virtual high-speed ferry and mode choice RP data. Finally, we got efficiently and interesting results, however some investigations are acquired.

    This study is aimed to develop a dynamic discrete choice model with latent market segments using panel data. The model system consists of two models: a latent segmentation model and a choice model with serial correlation. This model system is applied to panel data of shopping place choice. The estimation results shows that the latent segmentation model significantly improved goodness of fit and the choice model yielded more efficient parameter estimates by taking into account of serial correlation.

  • Discrete Choice Models with Latent Explanatory Variables Using Subjective Data

    Journal of JSCE   470 ( IV-20 ) 115 - 124  1993.07  [Refereed]

    Authorship:Last author

     View Summary

    Traditional discrete choice models for travel behavior use only manifest explanatory variables such as travel time and cost. Choice decisions, however, are strongly affected by latent factors such as comfort, safety, and reliability. Some authors have reported that using subjective ratings against those latent factors as explanatory variables gives better fit to the calibration data, but such an approach is rarely useful in forecasting. This paper proposes a methodology for incorporating choice data and subjective rating data to develop integrated models of choice behavior and psychological perception structure. The proposed models are based on the multiple-indicator-multiple-cause type model and the LISREL type model.

     View Summary

    Managing the cost of the long term care service is critically important to provide the better service to the aged people in the hyper-aged society. In such management, we need to be sensitive in keeping the necessary services in cutting the cost. Therefore, identifying what determines the aged people's service user is necessary. Mobility would be one of the keys to the decision making in choosing the service, because most of the nursing care service is related to the transportation: Nursing service offers not only facility care services but home nursing care including shopping assistance. In this study, we investigated the relationship between the transportation environment and the use of the service. We focused on those who do not use nursing service, despite the certification of the long-term care, in order to find why they do not use. We analyzed what led one to use or not use the nursing care service by using multilevel logistic regression analysis, because it allowed us to consider the difference of the error structure. We applied the model to the data of a local city in Japan. The result shows that some variables indicating accessibility significantly affected one's decision whether one uses the service or not. The accessibilities of car to clinic, hospital and neighborhood shops significantly affected the decision, while only the accessibility to the hospital was significant when one uses public transport. More than 50 percent of the aged people use motorcars to travel in this city, and this might be why more number of the accessibility by using the car significantly affected the nursing service use. We might be able to manage the cost of service use more effectively and efficiently through the accessibility improvement. use.

     View Summary

    We developed new methods for travel behavior analysis based on the fusion of huge and precise human trajectory data and implemented an urban management technique with multi-scale simulation that was able to describe human movements from the within-zone level to the between-zone level across the metropolitan area. We generalized the time discount term as GRL model by recursive expression and then clarified its theoretical properties. Moreover techniques of such as three-dimensional behavior analysis with Wi-Fi data, combined estimation with two kinds of behavioral data of different resolutions and automatic identification of behavioral contexts were proposed, which expanded the range of elemental analytical techniques for behavior in networks. By conducting these researches in conjunction with the evaluation of measures and plans on transportation in multiple cities, we confirmed the methods that had applicability to the real issues.

     View Summary

    In planning local transport service as an infrastructure, it is essential that the every resident is secured the minimum level of activity opportunity, such as medical service and shopping for daily life supported by local transport. Under this recognition, we developed a methodology that a local community select a combination of secured level of activity opportunity supported by local transport and the burden of operation cost to maintain the service based on capability approach. However, this methodology lacks a procedure for consensus building of residents. This study aims to bridge over the gap by developing a normative evaluation model for selecting local transport service based on the level of activity opportunity, and a survey technique of mutual mind under the un-biased recognition about the actual state of the area. These models were built in into the previously developed planning methodology as well as improved measurement model of the level of activity opportunity.

     View Summary

    The current focil fuel tax for road users has been accepted by public because it basically follows the beneficiary-pays principle. This taxation, however, will deviate from the principle when electric vehicles (hereafter EVs) reach masses. Toward the electric vehicle era, therefore, new policies such as road user charge system are needed.
    In this study, we analyzed proper toll amounts according to congestion levels, publically acceptable schemes, and EVs future demand. The results show that proper toll amounts of expressway to reduce congestion are -10 JPY for terminal charge, +5 JPY/km, and -17 JPY/km for distance charge in congested and non-congested road, respectively. Secondly, it was found that using the money from the road user charge for road maintenance raises the acceptability of pricing scheme. We also found that EV's demand is higher in suburban areas than city center.

     View Summary

    The simulation approach of transportation state is getting popular according to the development of the computational capacity, while more and more data can be available to measure the traffic state. Both approaches have advantages and disadvantages, respectively. So the assimilation of these approaches will give us more useful tool for the estimation of traffic states. In this study, we applied various type of data, such as the cell phone location data, the probe car data, the smartphone acceleration data and the ETC 2.0 data, besides the traditional person trip data. We also constructed the simulation systems that describe the individual travel behavior of one day, the travel mode choice by game situation, the pedestrian behavior and the traffic flow. The assimilation result through our empirical study indicated the efficacy of the proposed approach. As conclusion, we showed the general frame of this approach for traffic survey and management.

    これらの調査項目を約1ヶ月の間をおいて2度実施した.この1ヶ月の間に公共交通や山梨県の環境に関する情報や,行動データに基づいた二酸化炭素排出量などの情報を約半数の被験者に提供し,情報提供の有無による意識や行動の変化を観測した.
    この実験結果では,提案した仮説は棄却された.仮説が棄却された原因としては,サンプル数の問題による統計的有意性の問題もあるが,主に価値観意識が情報提供と関係なく発生していたことにある.これは,価値観意識というものが,非常に時間的に不安定であることを示している.これらについて検討を加えて,価値観意識を安定的にする要因は何であるか,また,そのための政策のあり方についての考察を行った.

     View Summary

    Information and communications technology (ICT) has evolved substantially and impacted urban residents' everyday life quite substantially in the past decade. The rapid spread of mobile telecommunications technologies has produced significant changes in relationships among communications, marketing and distribution, and transportation.
    The focus of this study is on how mobile telecommunication technologies have influenced daily activity and travel behaviors of urban residents. Temporal and spatial characteristics of their activity-travel patterns are empirically analyzed using activity diary data sets collected by the authors in the Kofu area of Japan. The survey is designed with the intent of capturing both patterns of movements in the urban area and patterns of activities that induced the movements. Questions regarding telecommunications activities are introduced into the activity-travel diary that had been developed by the authors to facilitate the acquisition of information on the occurrence and contents of telecommunications activities.
    The Survey of Communication, Activity and Travel, denoted by "SCAT," was conducted twice to form the database of this study. The first survey involved about 150 university students and data on weekly activity patterns and mobile telecommunication incidents were collected. The second survey addressed about 150 households (322 individuals) and activity diaries on two consecutive days and mobile telecommunication information were obtained.
    The first SCAT data are used to examine basic properties of ICT-activity-travel relationships of "heavy mobile-informed travelers" because students are certainly standing on the forefront of ICT use. On the other hand, the second SCAT data are used to analyze how characteristics of the joint activity engagement by household members are determined by the ICT usage among household members. Then, using both of the SCAT data sets, the hypotheses are examined and statistical evidence is presented. Finally, implications of the findings are summarized and directions are suggested for future research on ICT, activity and travel.

     View Summary

    Recently, many bus businesses in Japan have been in financial difficulty. Under such a background, some bus companies expect an intra-city night express bus service to be one of the promising policies to expand their market share. This study aims to identify the basic characteristics of night express bus between Kofu and Osaka and analyze users' consciousness and needs using a categorical regression analysis and a discriminating function analysis. Some empirical observations indicate that the annual deviations of the number of passengers are characterized as a monthly pattern, which is formed by non-workdays and excursion users. They also show that comfort of bus seat, space between seats, and baggage-space are regarded as a principal factor for user's evaluation.
    A cluster analysis was applied to classify user's activity pattern into four groups. Also, this study aims to identify relationship between the users' evaluation and their activity & travel patterns. An activity diary survey was conducted on the days when users riding on and getting off the bus. A LISREL model is calibrate considering determining factors such as individual attributes, the purpose of travel and scheduling conditions.

     View Summary

    This research investigated the impact of travel information provision on micro level, that is, individual's travel behavior, and macro level, transportation network of metropolitan area. Firstly, we developed a methodology to quantitatively evaluate the impact of traveler's pre-trip information considering transaction cost for travel behavior changes. The transaction cost was defined as the difference of expected utilities which are observed before and after travel behavior changes, and was estimated using a discrete choice model which represents mode choice behavior with and without the information on travel time respectively. We, then, developed a discrete choice model that incorporates non-compensatory decision making rules and attribute cutoff to explicitly consider the individual's information-processing capability. The model was empirically applied to the travel mode choice behavior under on-route traveler's information, and the result showed that the proposed model was superior in both reproducibility and prediction to the existing model in which an utility maximizing decision maker is assumed.
    Next, we investigated the impact of advanced traveler information system on transportation network demand of Chukyo metropolitan area using equilibrium assignment model. Two different approaches were proposed to relax the assumption of driver's perfect information. From the viewpoint that the actual route demand is equilibrate not in travel time level but in utility level, we first developed a methodology to amend link performance function in order to incorporate many unobservable factors other than travel time and cost. This method was empirically applied and the goodness-of-fit, especially in off-peak period, was dramatically increased. We, then, developed an equilibrium assignment method considering heterogeneity of network perception. More specifically, drivers were divided into different categories according to his/her cognitive level on the network configuration and travel time, and were assigned using different principle. The proposed model was applied changing the composition ratio of each categories, and the result showed that the goodness-of fit was the highest in the situation where about 20% of drivers chose his/her route with imperfect information. Finally, we estimated the user benefit of the advanced traveler information system that provides the shortest path information to the drivers.

    This research aims to analyze behavior of recreational travel by discrete choice modeling techniques. The research consists of three parts. The first part is to measure attractiveness of regions in terms of recreational activities. It has a form of a LISREL (Linear Structural Relationship) models that is estimated from psychometric data. Latent attractiveness is expressed by functions of physical characteristics of the region and identified by subjective judgments on the region. In the socond part is a discrete choice model with probabilistic choice sets is proposed to express destination choice behavior of recreational trips. The model has the choice set fromation stage and the choice stage. The first stage employs independent random constraint models that have the noncomplementary rule among attributes. In the third part more detailed travel behavior in a recreational area is modeled. It includes choices of departure time, destination, trip-chaining, and route. The model is used to evaluate road network improvement projects by forecasting departure time and destinations.

    This Research tried to arrange the actual situation of infrastructures. As a result, we found several important subjects, which are personal houses condition and living environmental equipments is not served well. And from the view point of transportation infrastructure there is not sufficient amount of capacity in metropolitan cities, of highway network and of airports. So, nations have much dissatisfaction about inconsistency between economical development and their living level. We arranged historical background of infrastructure institutions. Then we analyzed mathematical models in infrastructure demand forecasting, especially transportation infrastructures. To put it concretely, we constructed evaluating model for road network and travel demand forecasting model. This model can be applied to another kind of infrastructures. We concluded that economical activity is disturbed by insufficiency of infrastructure.
