This paper reports an empirical investigation on the expansion process of choice set integrating the information search approach and the cost-benefit approach. We hypothesized that the arising of interests in new alternative needs both initiative information search and considerable expected benefit. The latent mixture distribution structure equation models are developed and verified by a data set containing shopping behavior and attitudes. The results supported our hypothesis, suggesting that a lower satisfaction with the current set will incite external information search for all subjects, and that a higher expected benefit of expanding the choice set could induce a higher interest in new alternatives only when the considerable external information search was activated.

Maximal potential market for neighborhood car sharing is investigated considering optimization of car use within household. The maximal potential is not predicted from revealed or stated preference, but simulated based on the explicit rules that assign qualified travel demand by car to car sharing. Results of empirical analysis for Toyota City, Aichi Prefecture suggest that household fleet can be reduced by about 35% on weekdays and about 55% on weekends. Scale of the car sharing system is calculated that one vehicle per 10 households serves three trips a day. The results also suggest that potential demand is higher for households with light motor vehicles and areas close to train station.

Language：English

This study investigates the household behavior on car and motorcycle ownership in Asian metropolitan cities of Nagoya, Bangkok, Kuala Lumpur, and Manila. The household attitudes and behaviors on vehicle ownership are modeled using bivariate ordered probit (BOP) models. The accessibility is generally known to be correlated with vehicle ownership decisions. Accordingly, the accessibility is incorporated as an input for the proposed vehicle ownership model to explore the potential relationship among them. The mode choice models for the cities concerned were initially developed to quantify the accessibility variables that were later integrated into the vehicle ownership models. Inter-temporal and inter-regional comparison, and temporal and spatial transferability analysis have brought insights into the vehicle ownership modeling.

How routine is a routine? an analysis of the day-to-day variability in prism vertex location Reviewed

Transportation Research Part A Vol. 40 page： 259-279 2006

Language：English Publishing type：Research paper (scientific journal)

This study is concerned with how routine an individual's routine really can be. This question is addressed by examining the day-to-day variability of the time coordinate of the vertex of a time-space prism; in other words, by examining how the timeframe which governs the individual's daily schedule varies from day to day. When the timeframe varies, it is likely that the individual's behavior also varies. When the timeframe is stable, on the other hand, a routine can be maintained. The analysis presented in this paper attempts to determine how much of the variation in travel is due to the variation in the timeframe. The origin vertices of workers' morning prisms, which determine how early they can leave home in the morning, are examined in this study, along with the departure times of the first trips in the prisms, which are mostly supposedly routine commute trips. The results indicate that the vertices are located with a much smaller variance, but vary more systematically than do the departure times of the first trips in the prisms. This implies that a large degree of variability is introduced when a trip is made within the timeframe as determined by a prism vertex. It is also shown that the departure time varies from worker to worker according to unobserved heterogeneity—i.e., unexplained differences across individuals—much more than does the prism vertex. The study results indicate that large degrees of flexibility are associated with trip making, and suggest the presence of room for behavioral modification with respect to workers' first trips in the morning.

International Journal of ITS Research Vol. 4 page： 21-28 2006

Language：English Publishing type：Research paper (scientific journal)

Probe vehicles are promising tools for collecting travel time data because of their ability to provide large amounts of real-time information. However, there are many obstacles to the practical deployment of probe vehicles, one of which is the enormous expense of data transmission. This study attempts to assess the effects of differing transmission intervals (and therefore costs) on the quality of travel time data collected. Two accuracy/error values are examined: map-matching accuracy and the mean absolute percent error (MAPE) of link travel information. In order to determine the most cost-effective probe transmission frequency, the accuracy elasticity of cost is compared for six different ratios of data transmission charge to total communication cost.

Proceedings of 5th ITS Symposium 2006 page： 335-340 2006

Language：English

One serious problem of continuous large-scale data collection with probe vehicle is the dilemma of balancing the cost economization and system reliability improvements. The polling frequency is found to be the major factor that determines the operation cost of a probe vehicle-based traffic data collection system. This paper focuses on evaluating the cost-effectiveness of probe data at various space-based intervals, which are expected to provide roadway travel time estimation at certain reliability. The proposed optimization framework concentrates on the least total operation cost by combining the polling frequency and the required probe size, which gives a simple and valuable solution on the issue of cost-effective traffic data collection.

Development of Dynamic Route Guidance System “PRONAVI"Based on Probe-Vehicle Information

page： 147-152 2005.11

Language：Japanese

A dynamic route guidance system 'PRONAVI' is introduced. PRONAVI is one of the in-vehicle navigation systems, which comprises a central server and terminals connected over the Internet. When a destination is selected on a terminal, the central server calculates the time required to reach it from the point of departure and send the results to the terminal. The key feature of the system is the intensive use of various kinds of information including not only widely provided VICS but also probe vehicle information and weather forecast. The information is used for the real-time route guidance, and also, stored in the center server and used to forecast the future traffic condition combined with the real-time information later.

Preprint CD-ROM of the 84th Annual Meeting of the Transportation Research Board page： CD-ROM 2005

Language：English

The development of activity-based travel demand modeling systems ushers in a new era in transportation demand forecasting and planning. This paper describes a comprehensive multimodal activity-based travel demand forecasting system developed for implementation in the State of Florida. The effort has resulted in the development of FAMOS, the Florida Activity Mobility Simulator. FAMOS consists of two main modules that together comprise a microsimulation model system for modeling activity-travel patterns of individuals. They are the Household Attributes Generation System (HAGS) and the Prism-Constrained Activity Travel Simulator (PCATS). The model system has been developed and estimated using household activity and travel data collected in Southeast Florida in 2000. Results of the model development effort are very promising and demonstrate the applicability of activity-based model systems in travel demand forecasting practice. This paper provides an overview of the model system together with a description of its features and capabilities and preliminary validation results.

Analysis of user impressions of railway stations, focusing on the effects of adjunct retail facilities

Language：English Publishing type：Research paper (scientific journal)

This paper examines the cognitive structure of the impressions that users have of railway stations and quantifies the effect of different types of adjunct stores on the cognitive structure. The results offer some fundamental insights for developing more effective policies and promotion strategies.
User feelings of Tokyo's large railway terminals were gathered by means of a questionnaire. Overall impressions of the stations were then extracted using factor analysis. A structural equation model (SEM) was applied to see how stores affect the user's impressions of the stations as well as to quantify the impact of the stores and the differences in the users' socio-economic characteristics.
The results suggest that railway users have three types of impressions about stations: convenience, when a station is mainly considered a transport facility; pleasure, when a station is mainly considered a place of communication or leisure; and crowded, which concerns the station's layout and atmosphere. Different types of stores produced different impressions. Clothing stores enhanced the impression of pleasure, while food & beverage stores enhanced the impression of convenience. The revealed shopping behaviour data confirmed that these latent variables affect the railway user's choice of shopping destinations.

Driver's route choice behavior and its implications on network simulation and traffic assignment

Simulation Approaches in Transportation Analysis: recent advances and challenges page： 341-369 2005

Language：English Publishing type：Research paper (scientific journal)

The principle of driver's route choice has long been the shortest path with a fixed time penalty of a toll. It is also seen that traffic is assigned on the road network based on user equilibrium with perfect information assumption. This paper demonstrates two empirical studies that pose a question to these traditional assumptions to better understand route choice behavior. Multi-class user equilibrium assignment with imperfectly informed drivers' classes is applied to a metropolitan area network first. Next, route choice behavior is directly observed and analyzed using probe car data.

Simulation analysis of a multiple-station shared vehicle system without vehicle redistribution Reviewed

Journal of Infrastructure Planning and Management Vol. No. 786/IV-67 page： 11-20 2005

Authorship：Lead author Language：Japanese Publishing type：Research paper (scientific journal)

Without redistribution of vehicles by operator, a multiple-station shared vehicle system may not meet all the demand, because the vehicles in the fleet may be distributed unevenly across the stations due to the directionality in demand, making it impossible to accommodate demands with certain combinations of origin and destination stations. A simulation model is developed to investigate the effects on system performance of many factors including the number of stations, the number of vehicles, the parking capacity, the size of the demand, and the one way trip rate. System performance is represented by a set of measures including the number of trip served by the system and the total time the vehicle is in use. The results suggest that the performance of a system with 100 stations and that of 10 systems with 10 stations each are the same if the other conditions are the same, and that increasing the number of the parking stalls is more effective than increasing the number of stations.

ousehold car and motorcycle ownership behaviours in the Chukyo Metropolitan Area have been analysed focusing on 1) traffic convenience in residential area, 2) interrelationships between car and motorcycle ownership, and 3) secular changes of the ownership behaviours. Some accessibility measures, based on expected maximum utility of mode choice models, are examined to explain the convenience and bivariate ordered probit models are applied to describe the ownership. Models estimated are inter-temporally compared, and their transferability is examined. Complementary relationships between car and motorcycle ownership, the secular changes of factors affecting the ownership, and accessibility measures related to higher transferability are shown.

Proceedings of the 10th World Congress on Intelligent Transport Systems, November 16-20, 2003, Madrid, Spain 2003

Language：English

The relationship between the travel speed at the main road and that detouring through neighborhood streets is examined by using the probe car information. The results suggest that the two travel speeds are positively correlated, implying that more drivers detour from the main road to the neighborhood street when the congestion at the former is severer. The results also show that the travel speed through the neighborhood streets has considerable variances regardless of the travel speed at the main road.

Language：English Publishing type：Research paper (scientific journal)

The methodology for weighting endogenous samples is extended in this study and applied to a multi-dimensional choice-based sample and an enriched sample. It is shown that a unified weight exists for a sample obtained from a complex endogenous sampling scheme. Problems with conventional weighting methods for samples from endogenous sampling, such as roadside surveys, are pointed out and an improved weighting scheme is proposed. Coefficient estimates of discrete choice models with and without weights are compared, and the importance of applying appropriate weights and a valid covariance estimator is pointed out.

Language：English Publishing type：Research paper (scientific journal)

This study addresses the issue of how accurately parameters characterizing a stochastic, discrete behavioral process can be estimated using data from a discrete-time panel study. Specifically, the study examines the likelihood and magnitude of error in estimating the parameters characterizing the behavioral process based on observations of the process obtained at discrete time points. The results of the study offer strong indications that the likelihood and magnitude of error can be both very large. Furthermore, reducing the interval between survey waves improves estimation accuracy but only very slowly. The study results point to the need to obtain continuous data as accurately as possible from surveys made at discrete time points, using carefully designed and administered recall questions.

Language：English Publishing type：Research paper (scientific journal)

The notion of time-space prisms has often been used in the context of describing activity-travel patterns of individuals. This paper presents a methodology for estimating the temporal vertices of time-space prisms using the stochastic frontier modeling technique. Observed trip starting and ending times are used as dependent variables and socio-economic characteristics and commute characteristics serve as independent variables. The models are found to offer plausible results indicating that temporal vertices of time-space prisms, though unobservable, can be estimated based on temporal characteristics of observed activity-travel patterns. Comparisons of stochastic frontier models of prism vertices and the distribution of prism vertices are presented using two activity data sets collected in the United States – San Francisco and Miami. Differences and similarities in temporal vertex locations are highlighted in the paper.

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Non-compensatory models of driver's choice on dynamic park and ride are developed and examined on the predictability in this study. One of the data mining tools, C4.5, is used to develop decision tree and production rules of driver's choice. The generated decision tree and production rules are compared with the semi-ordered lexicographic model developed in the preceding study. Compared are the similarity of the estimated decision making structures and the distribution of the segments not correctly represented by the models as well as goodness-of-fit and hit ratio. The comparison shows that the semi-ordered lexicographic model has a higher goodness-of-fit and hit ratio than models with data mining tools. The results also suggest that the models developed in this study represent different decision rules from, but have similar distributions of the segments not represented by the models with the semi-ordered lexicographic model. Empirically, the consistent results by models with data mining tools and the semi-ordered lexicographic model suggest that the parking congestion level in CBD has a significant effect on the choice behavior.

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Decision trees and production rules, which are among the methods used in knowledge discovery and data mining, are applied in this study to investigate drivers' route choice behavior. These methods have an advantage over artificial neural networks, another data mining method often used in the analysis of travel behavior, that they facilitate the determination of the relationships between the explanatory variables and the choice. Specifically, the C4.5 algorithm, which produces a decision tree and a set of production rules from the tree, is applied in this study. Two surveys were carried out to collect data on drivers' route choice behavior between two alternative routes on expressway networks. The two data sets include the expected minimum, maximum and average travel times along each alternative route as indicated by the respondent, as well as his socio-demographic attributes. The results of the analyses suggest that different expected travel times influence route choice in different cases, and that a maximum or average travel time determines route choice in some cases regardless of other attributes. The results of a comparison analysis between the C4.5 algorithm and discrete choice models indicate the superior ability offered by the former in representing drivers' route choice.

A Simulation Analysis for the Management of an Electric-Vehicle Sharing System: The Case of the Kyoto Public-Car System Reviewed

Language：English Publishing type：Research paper (scientific journal)

A multi-station electric-vehicle (EV) sharing system has been in operation on an experimental basis in Kyoto, Japan. Members of the system can check out EVs at a station and return them at any station. To reduce the cost of system operation, EVs are not reallocated to stations by the operator. This feature, at the same time, may delimit the efficiency of the system because of the mismatch between the spatial distribution of the demand and the distribution of the EVs among the stations. We construct a simulation model of system operation, and configure the optimal management of the system using genetic algorithms, with the number of checkouts per vehicle set as the objective function to be maximized. The number of vehicles, parking capacity at each station and number of members are among the decision variables. The results suggest that the optimal number of EVs is about a half of the total number of parking stalls. This implies that the efficiency of the system does not necessarily improve as more EVs are introduced. Also, the results suggest that even if a new station is introduced into the system, the efficiency does not necessarily improve.

Modeling the Simultaneity in Injury Causation in Multivehicle Collisions Reviewed

Transportation Research Record ( 1784 ) page： 143-152 2002

Language：English Publishing type：Research paper (scientific journal)

Constrained by the single-equation specification, traditional logit or probit models for traffic accident severities can only model one severity at a time. Single-equation models fails to account for the simultaneity of injury severity outcomes in multivehicle collisions. An attempt to account for this simultaneity is made by presenting a simultaneous logit model of endogenous interrelationships among injury severities in multivehicle collisions. Car-truck collision data in Washington State between 1990 and 1996 are used for a simultaneous binary logit model to determine the effects of various exogenous factors in the presence of injury simultaneity, and empirical comparisons with traditional single-equation logit models are also provided. The methodology presented provides for significant efficiency gain when correlation between injury severities is high and can easily be extended to multiple severity categories in multi-vehicle collisions. Empirically, it is also found that parameter estimates for key roadway design variables may vary greatly between a simultaneous logit and its single-equation counterparts. Another finding from this methodology is that preventive measures for head-on collisions, or enforcement of drunk-driving regulations among truck drivers, as well as limiting the occurrence of high-speed curve designs on truck routes, appear to be the most likely factors for significant potential savings in social costs from car-truck collisions.

Authorship：Lead author Language：English

French government has implemented a periodical vehicle inspection program, which aims at maintaining proper functioning of the vehicle and ensuring the emissions control systems installed on the vehicle work properly. Also, an incentive program for scrapping old vehicles was introduced in 1994 through 1996 to promote the replacement of those vehicles with higher emissions by newer vehicles with lower emissions. A hazard-based duration model of household vehicle transaction behavior has been developed in this study to examine the effects of the inspection program and the grant for scrappage on vehicle transaction timing. The model is developed as a competing risks model assuming the following three types of competing risks: replacing one of the vehicles in the household fleet, disposing of one vehicle in the fleet, and acquiring one vehicle to add to the fleet. The empirical analysis is carried out using the panel data of French households' vehicle ownership from 1984 to 1998, obtained by the panel survey called Parc-Auto, which has been conducted by a French marketing firm, SOFRES, since 1976. The long panel observation period facilitates the introduction of macro-economic indicators into the model, enabling the analysis to distinguish the effects of policy measures from macro-economic factors. The empirical results indicate that the expected vehicle holding duration becomes 1.23 times longer under the inspection program than before the program commenced, given that the vehicle is replaced by another vehicle at the end of the holding duration; and that the conditional probability of replacing a vehicle aged 10 years and over becomes 1.19 times higher when the grant for scrappage is available.

Preprint CD-ROM of the 81th Annual Meeting of the Transportation Research Board 2002

Authorship：Lead author Language：English

Previous studies have examined injury severity of vehicle accidents in relation with human factors, vehicle type, highway design, and environmental conditions. Several types of statistical models of injury severity have been developed based on driver's injury in some studies, and on most severely injured occupant's severity in others. A bivariate ordered-response probit model of driver's and most severely injured passenger's severity in collisions with fixed objects is developed in this study. Exact severity of passenger is not necessarily observed, especially when only most severe injury of the accident and driver's injury are recorded in the police reports. To accommodate passenger severities as well, we explicitly develop a partial observability model of passengers' injury severity in multi-occupant vehicle. The model has consistent coefficients for the driver's severity between single-occupant vehicle and multiple-occupant vehicle accidents, and provides more efficient coefficient estimates by taking into account the common unobserved factors between driver's severity and passenger's severity. The results of the empirical analysis using 4-year statewide accident data in Washington State reveal the effects of driver's characteristics, vehicle attributes, types of objects, and environmental conditions on both driver's and passengers' injury severities, and that their severities have different elasticities to some of the risk factors.

Infrastructure Planning Review Vol. 19 page： 481-487 2002

Language：Japanese Publishing type：Research paper (scientific journal)

A promising approach for expedient market penetration of electric vehicles is a multi-station electric vehicle sharing system. Such a system, however, contains several problems, e.g., vehicles may concentrate at particular stations, deterring efficient operation of the system. The parameters that define system operation must be set at their optimal values for efficient operation. Genetic algorithms are used in this study along with a simulation model of the vehicle sharing system to optimize system operation and to examine ways to attain efficiency in system operation. It is founded from the results that the total number of parking slots needs to be twice as many as the number of vehicles and that adding a new station does not necessarily improve the efficiency of system operation.

These functions are developed as neural networks. The effectiveness of the system is examined using an experimental data set.

A hazard-based duration model of household vehicle transactions behavior is developed in this study to examine the effects of Japanese periodic inspection program, and an empirical analysis is carried out using the data set obtained by a panel survey conducted in Kyoto City. The results of model estimation suggest a higher probability of replacing or disposing of a vehicle whose inspection is scheduled within the next 6 months. Results of a simulation-based scenario analysis indicate that a raise in the inspection cost accelerates the replacement of vehicles households own without affecting the number of vehicles they own, and that the extension of the inspection period decelerates the scrappage of vehicles and increases the number of vehicles households own.

Unlike commute trips, business trips are generated throughout business hours, and several destinations tend to be visited in a trip chain. In this study, a route and departure time choice model for a business trip chain is developed based on the hypothesis that the trip chain is made so as to minimize the total cost, including costs associated with other business activities before and after the trip chain, as well as costs associated with travel time, toll fees, and the probability being late. The empirical analysis is carried out using a data set obtained from a survey of business trip drivers. The properties of the estimated model are examined on a sample case

Simultaneous vehicle type and main driver choice models and models of vehicle miles traveled are developed for one and two vehicle households separately. The types of vehicles are categorized as eight alternatives, and unobserved correlations among them are examined by adopting mixed multinomial logit models. The empirical results suggest that the vehicles are possibly reallocated in two-vehicle households at the transactions, that there exist inclinations toward specific types of vehicles among two-vehicle households, and that they have the tendency to obtain the same type of vehicles. The results also suggest that the vehicle miles traveled by respective vehicles in two-vehicle households are negatively interacted and that the vehicle types do not affect the vehicle miles traveled in two-vehicle households while they do so in one-vehicle households.

The problem of determining the interval between waves of panel surveys, the sample size, and the study duration is formulated in this study as an optimization problem in which the sum of the cost of estimation error and the cost of the survey is minimized. Numerical analyses using hypothetical parameter values indicate that the optimal sample size of a panel study can be much smaller, and the optimal inter-wave interval and the optimal study duration much shorter, than those values that have typically been used in previous panel studies.

A destination choice model is developed, using a coordinates-based methodology, to resolve the problems arising from zone systems on which most models developed so far are based. To evaluate destination choice probabilities and simulate choice simulation on a hypothetical uniform area is almost identical to the theoretical distribution, suggesting the validity of the MCMC method. From the result of a simulation run in Kyoto, it is confirmed that the MCMC method is a useful technique as a method of forecasting destination choice behavior with huge choice sets.

Travel survey data from two major metropolitan areas of Japan, taken at three time points spanning a period of 20 years, are analyzed and changes in travel characteristics and the spatial distributions of jobs and residences are examined. The two areas, the Kyoto-Osaka-Kobe (Kei-Han-Shin) metropolitan area and the Nagoya-Gifu (Chukyo) metropolitan area, developed along rail networks prior to the process of motorization began in the 1960's in Japan. Changes in travel characteristics in these two areas are examined using two sets of repeated cross-sectional data. The data cover the period from 1970 through 1990 in which these metropolitan areas experienced rapid growth and motorization. The analysis focuses on changes over time in mode use, commute trip length, daily travel time expenditure, and trip-chaining characteristics, and explores their associations with trip end location, residence and job locations, and other spatial factors. Changes in urban structure are inferred through the examination of the spatial distributions of job locations, residence locations, and activity locations. As a new indicator of urban structure, the spatial distribution of person-hours by activity type is proposed, and its effectiveness in portraying, along the time as well as spatial dimensions, the internal structure of an metropolitan area and the distribution of economic activities therein, is examined.

It is often the case that a discrete choice model cannot be applied to forecasting because the choice set is unmanageably large and choice probabilities cannot be evaluated in a practical manner. For example, an activity-based analysis of travel behavior often involves an astronomical number of potential activity-travel patterns, resulting in an enormous choice set when one attempts to formulate the behavior as a discrete choice. A colossal choice set makes it practically impossible to define the full choice set and to evaluate the choice probability of each pattern for forecasting. This paper demonstrates an algorithm to simulate individuals' activity-travel choice by sampling activity-travel patterns from a colossal choice set according to their choice probabilities as determined by a discrete choice model, without enumerating the full choice set. Numerical examples are presented to demonstrate the practicality and effectiveness of the algorithm in forecasting the effects on activity-travel patterns of transportation policy measures.

Driver behavior under congestion pricing is analyzed in this study to evaluate the effects of alternative congestion pricing schemes. The analysis, which is based on stated-preference survey results, focuses on time allocation, departure time choice and route choice when a congestion pricing scheme is implemented on toll roads. A unique feature of the model system of this study is that departure time choice and route choice are analyzed in conjunction with the activities before and after the trip. A time allocation model is developed in this study to describe departure time choice, and a route and departure time choice model is developed as a multinomial logit model with alternatives representing the choice between freeways and surface streets and, for departure time, choice from among before, during, or after the period when congestion pricing is in effect. The results of the empirical analysis suggest that departing during the congestion pricing period tends to have higher utilities, and that a worker and a non-worker have quite different utility functions. The comparative analysis of different congestion pricing schemes is carried out based on the estimated parameters, and the results suggest that the probability of choosing each alternative is stable even if the length of the congestion pricing period changes, but that a higher congestion price causes more drivers to change the departure time to before the congestion pricing period.

An Analysis of Household Vehicle Holding Durations Considering Intended Holding Durations Reviewed

Transportation Research Vol. 34A ( 5 ) page： 339-351 2000

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

Household vehicle holding durations are examined in this study using panel data. Panel data enable the observation of changes in household vehicle holdings in discrete time periods. If the data set contains retrospective recall data which offer information on the types and the occurrence time points of the transactions since the last survey, direct observation of the transaction process along a continuous time axis is possible. Furthermore, if the data contain information on intentions for future transactions and actual outcomes of the intentions in later waves, the relationship between intended transactions and actual transactions can be observed. In this study, we develop models of actual vehicle holding durations and models of intended vehicle holding durations for the same set of vehicles. Comparing these two sets of models, the effects on household vehicle holding durations of changes in the household's plans for vehicle holding and unexpected events can be inferred. To represent unaccounted associations between intended vehicle holding durations and actual vehicle holding durations, vehicle specific error components are introduced into the duration models. A non-parametric approach is adopted in model estimation using mass points, which requires no assumption on the distribution of the error components.

Language：English Publishing type：Research paper (scientific journal)

A methodology to estimate the location and size of space-time prisms that govern individuals' activity and travel is presented in this study. Because the vertices of a prism are unobservable, stochastic frontier models are formulated to locate prism vertices along the time axis using observable trip starting or ending times as the dependent variable, and commute characteristics, personal and household attributes and area characteristics as explanatory variables. Models are estimated successfully with coherent behavioral indications. A mean difference of 1.46 hours is found between the observed trip ending time and the expected location of the terminal vertex for workers' evening prisms. The estimation results aid in enhancing our understanding of prism constraints by identifying the determinants of prism vertex locations.

Public intentions and preferences should be reflected in transportation planning, because it is the public that receive benefits from and incur costs of transportation policies. It is thus desired that planners have a grasp of public attitudes toward each of the policies they implement. In this study, we develop a discrete-choice model of individuals' importance ratings of transportation policy measures using socio-demographic attributes and the transportation levels of service as its explanatory variables. We also analyze the differences in individuals' importance ratings between the case they value policies from their own perspectives and the case where they do so considering the entire community. The results reveal differences in individuals' importance ratings between the two positions, and suggest that the individuals' attitudes vary by area of residence and according to their socio-demographic attributes.

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.

A generating system of future household's attributes is developed in this study. The system creates the weight for each sample case obtained from the disaggregate survey to match present multiple aggregate marginal distributions, and simulates the demographic changes in each sample household along the time dimension. The simulation results applied to Osaka City suggest that the distributions of the number of trips or vehicle-holdings differ from those obtained by a conventional weighting method, that the system predicts population and number of households for the year 1995 fairly well using the data from 1990, and that the distribution of the predicted 2020 populations by repeated simulations has a high kurtosis.

On the Effects of Competition for Household Vehicles on Household Members' Mode Choices Reviewed

Infrastructure Planning Review Vol. 17 page： 583-588 2000

Authorship：Lead author Language：Japanese Publishing type：Research paper (scientific journal)

In a household with fewer vehicles than household members, the use of a household vehicle by one member decreases its availability for other members. A model of mode choices by household members is developed as a vehicle allocation model in this study while taking into account the exclusiveness in vehicle use. A two-level nested logit model is applied where the choice by the main driver of a household vehicle is placed at a higher level and the allocation of the vehicle to other members in a lower level. The scale parameter is structured to represent the heterogeneity across households. The results of empirical analysis suggest that some improvement of the model's goodness-of-fit is gained by considering the exclusiveness in vehicle use, and that the main drivers who are household heads or drive standard-size vehicles are less altruistic.

Language：English Publishing type：Research paper (scientific journal)

Motorization is a self-reinforcing process which involves positive feedback. Using a simple model of bi-modal transportation system, it is shown that a transportation system may eventually be dominated by the automobile, or may equilibrates at a grossly inefficient point due to social dilemmas associated with automobile use. Furthermore, in areas with well developed public transit, road capacity addition can be detrimental not only to the public transit but also to the automotive transportation. TDM measures are conceived in this study as mechanisms to prevent the divergence of the motorization process away from a social optimum due to its positive feedback and social dilemmas. A simple model of bi-modal transportation system and a cellular automata model of individuals' TDM compliance behavior are combined in the study to see how TDM measures that rely on individuals' voluntary cooperation may be effective. Results of simulation analyses based on the model are presented.

Infrastructure Planning Review Vol. 16 page： 553-560 1999

Language：Japanese Publishing type：Research paper (scientific journal)

Household vehicle ownership behavior in earlier stages of motorization is governed by not only economic but also psychological and sociological factors. The study proposes the concept of “symbolic utility", which refers to psychological satisfaction from vehicle ownership. Based on analyses of the causal structure among attitudes towards and perception of vehicle ownership, a model system of vehicle ownership preference of non-owners is developed. The results suggest that attitudinal variables have effects on vehicle ownership preference, and the accuracy of vehicle ownership choice models could be improved by taking symbolic utility into consideration. The study results also indicate the presence of cognitive dissonance of non-owner households and “Veblen effects" of vehicle ownership.

In this study, a simultaneous choice model system of monetary and time expenditures, location, and frequencies of discretionary activities is developed under the hypothesis that an individual attempts to maximize the total utility of engaging in activities, by adjusting the monetary and time expenditures, and frequencies of the activities. Mixing distribution models were combined with Tobit models to estimate the unknown parameters. The model components in the system were estimated sequentially. Estimation results using a data set from Kyoto city revealed the effects on the discretionary activities of the attributes of the individual, the travel circumstances as well as the attributes of the destination locations.

A structural equations models system, whose endogenous variables are household transportation energy consumption, work trip travel mode, vehicle holdings, and commute distance, is developed using the results of 1990 Kei-Han-Shin (Kyoto, Osaka and Kobe) household travel survey. The energy consumption characteristics of the household are explored using the model system, and the effectiveness of alternative land-use policies in reducing transportation energy consumption is evaluated by applying the model system while treating the commute distance as an exogenous variable. The estimation results indicate that it is possible to reduce household energy consumption by promoting high density land use development and encouraging job-residence proximity. In the Kei-Han-Shin metropolitan area where high-density and mixed land use already prevails and auto use is relatively low, however, an attempt to reduce household transportation energy consumption appreciably would require policies that target households of higher propensity toward energy consumption which tend to reside in the outskirts of the metropolitan area and commute long distances.

Transportation Research Record ( 1676 ) page： 61-67 1999

Language：English Publishing type：Research paper (scientific journal)

Household vehicle ownership behavior is governed by not only economic considerations but also psychological and sociological factors. The latter factors are expected to play important roles in earlier stages of motorization. Previous disaggregate models of household vehicle ownership behavior, however, have been developed mostly for countries with mature motorization and most often have included only economic factors as explanatory variables that determine the utility of a household vehicle. These models are limited as models of vehicle ownership behavior in earlier stages of motorization if psychological and sociological factors are in fact significant determinants of household vehicle ownership decision. Considered in this study is the concept of “Symbolic Utility" of vehicle ownership, which refers to psychological satisfaction from owning and using a vehicle. Based on analyses of the causal structure among attitudes towards vehicle ownership, a vehicle ownership model system is developed in the study. The results of this study suggest that attitudes towards vehicle ownership have effects on vehicle ownership preference, and the accuracy of vehicle ownership choice models can be improved by taking symbolic utility into consideration. The results of the model estimation also indicate the presence of cognitive dissonance of non-owner households and “Veblen effects" of vehicle ownership.

in this study. The model is developed assuming the following three types of competing risks: replacing one of the vehicles in the household fleet, disposing of one vehicle in the fleet, and acquiring one vehicle to add to the fleet. In addition to the attributes of household, changes in household attributes are expected to have strong effects on vehicle transactions behavior. To account for their effects, dummy variables indicating the occurrence of a change in selected household attributes are defined as time varying covariates and introduced into the model. In addition, vehicle transactions themselves change the needs and motivations for vehicles holding, affecting the timing and the type of the transaction that immediately follows. Dummy variables indicating the type of the preceding transaction are also introduced as time varying covariates into the model. The results of the empirical analysis using a data set collected in a panel survey empirically support the theoretical considerations underlying the model development, and indicate that the effects of changes in household attributes and that of a preceding transaction are well represented in the model.

The behavior of time allocation to two types of discretionary activities is formulated as a doubly-censored Tobit model. The model is capable of incorporating cases where the entire amount of time available for discretionary activity is allocated to one type of activity and the other type of activity is not engaged at all. The model is applied to examine individuals' allocation of time to in-home and out-of-home discretionary activities on working days and non-working days, using a weekly time-use data set from the Netherlands. Workers' daily activity patterns vary significantly between working days and non-working days, while it can be expected that patterns of time allocation are correlated between working days and non-working days. A set of error components is introduced into the model to represent this correlation, adopting a mass point approach which requires no assumption about the distribution of the error components. The validity of the model is examined statistically.

Language：Japanese Publishing type：Research paper (scientific journal)

In this paper, a household vehicle transactions model is developed for a better understanding of households' vehicle holdings behaviour which substantially affects their travel behaviour. A competing risks hazard-based duration model is applied to households' transactions behaviour by assuming the three risks, replacement, acquisition, and disposal. In order to account for interactions among transactions and effects of changes in households' characteristics, time-varying covariates are introduced into the model. The empirical analysis reveals interactions among transactions and the effects on transactions behaviour of changes in households characteristics.

Household vehicle holding durations are examined for a better understanding of household vehicle transaction behavior. It is assumed in this study that observed transactions include planned and unplanned transactions. The objective of the study is to determine the differences in the distribution of vehicle holding durations between planned and unplanned vehicle transactions. The relationship between actual vehicle holding durations and intended vehicle holding durations are determined by comparing the revealed preference models and intention models. Based on these two sets of models, differences in distributional characteristics in vehicle holding durations are statistically inferred between planned and unplanned vehicle transactions.

Transportation and Traffic Theory: Proceedings of the 13th International Symposium on Transportation and Traffic Theory page： 431-453 1996

Language：English Publishing type：Research paper (scientific journal)

A discrete﷓continuous choice model of time allocation to two types of discretionary activities is formulated based on the concept of random utility maximization. The model development takes into account the discreteness inherent in daily activity engagement and time allocation (i.e., one type of activity may not be engaged, therefore no time may be allocated to it at all, during a day). Without requiring simplifying assumptions other than the one that at least one of the two types of activities will be engaged, the utility model is formulated as a doubly﷓censored Tobit model.
This theoretical framework is applied to study daily time allocation to in﷓home and out﷓of﷓home discretionary activities while using, as explanatory variables, work schedules and commute characteristics as well as residential, household and personal attributes. A weekly time﷓use data set from the Netherlands is used in the statistical analysis. To account for heterogeneity in the data set comprising repeated measurements of daily time use for each respondent, an error component is introduced into the doubly﷓censored Tobit models. A non-parametric approach is adopted for model estimation using mass points. Behavioral implications of model estimation results are discussed. The validity of a procedure to correct estimated t-statistics proposed for repeated measurement data is also discussed.

A Model Choice Model which Accounts for Vehicle Availability as Determined by Intra-Household Interactions Reviewed

Toshiyuki Yamamoto, Satoshi Fujii, Hiroshi Yoshida and Ryuichi Kitamura

Infrastructure Planning review Vol. 13 page： 535-542 1996

Authorship：Lead author Language：Japanese Publishing type：Research paper (scientific journal)

Misspecification of the decision maker's choice set causes inconsistent estimation of discrete choice model. This study presents a methodology to account for the heterogeneity in travel mode choice sets that results from vehicle availability. Assuming vehicle availability is affected by intra-household interactions and varies from time to time, this study develops a linear structural equations system of vehicle availability while taking intra-household interactions into account.
