A Household Attributes Generation System for Long-range Travel Demand Forecasting with Disaggregate Models Reviewed

Satoshi Nishida, Toshiyuki Yamamoto, Satoshi Fujii and Ryuichi Kitamura

Infrastructure Planning Review Vol. 17 page： 779-787 2000

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

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

Toshiyuki Yamamoto, Ryo Umeki and Ryuichi Kitamura

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.

Self-reinforcing motorization: can travel demand management take us out of the social trap? Reviewed

Ryuichi Kitamura, Shoichiro Nakayama and Toshiyuki Yamamoto

Transport Policy Vol. 6 ( 3 ) page： 135-145 1999

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.
