概要

SimTread has been developed as a pedestrian simulation system with straightforward pedestrian and space model, which is highly operable by the users. The pedestrian model is a multi agent system in which the individual pedestrian is modeled as agents, and the space model is based on real coordinates, on the contrary of network and mesh models, that enable to represent plans directly into models. The characteristics of crowd represented in this system had been evaluated through test cases by measuring the flow rate that is a major index for evaluating crowd. Major results are as follows 1. In a simple plan that are comparable to network models, SimTread showed reasonable behaviours of crowds, which in terms of operability, can be concluded as highly desirable performance. 2. In a case where a bottleneck accumulates enough pedestrians so that consecutive exits will be virtually closed, SimTread showed accurately the propagation of crowd, which led to qualitative analysis of the crowd.
