Abstract
This research describes construction of a traffic simulator that includes dynamic characteristics of each vehicle and each driver as well as environmental information. As a basic design for the traffic simulator, interaction of vehicles is examined. As a vehicle model, a dynamic model of 3 degree-of-freedom is used in consideration of total calculation time. As a driver model, a risk model is used based on the risk sense. To examine longitudinal interaction and lateral interaction in traffic flow, following algorithm and lane-change algorithm are constructed for a traffic simulator.
