Inter-Regional Travel Demand Analysis Using Integrated Model For Practical Travel Demand Forecast

Abstract

This paper presents a latest inter-urban travel demand model for Japan. It intends the travel demand analysis for private business planning rather than government-based transportation planning. Cross-sectional data from the 2005 Interregional Travel Survey, Japan, is used for the model estimations. The model consists of three sub-models: a trip modal choice sub-model, trip distribution sub-model, and tip generation/attraction sub-model. The trip modal choice sub-model is a nested logit model including an upper tree choice of automobile and public transportation and a lower tree choice of rail, bus, and air transportation; the trip distribution sub-model is an aggregated logit model; and the trip generation/attraction sub-model is a log-linear regression model. The models are verified by comparing the estimated results with the observed data. The proposed model successfully reproduces the current travel demand.
