SPATIO-TEMPORAL DISTRIBUTION OF RAILROAD USERS FOR DISASTER PREVENTION PLANNING

Abstract

Considering provisions for human damage due to a large earthquake, it is important to understand the characteristics of the spatio-temporal distribution of population in urban area. In this paper, we construct a model which simulates, on geographic information systems, the route choice behavior and transfer behavior of railroad users. The spatiotemporal distribution of users is estimated by applying the model to the Tokyo metropolitan area, using the data taken from a person-trip survey. Some numerical examples using the proposed model are shown for detailed disaster prevention planning.
