A Full Driving Simulator of Urban Traffic including Traffic Accidents

摘要

This paper describes a model for traffic simulation of an urban environment and its implementation in a driving simulator. The simulator is also able to reproduce realistic traffic accidents. In order to attain real-time simulation, the simulation environment has been partitioned considering the city as divided into segments of road, junctions, and sectors that minimize the interaction between the cars involved in the traffic simulation and the traffic simulation is considered only in a control zone centered on the driven vehicle. Simplified dynamic vehicle models have also been used when vehicles are not involved in the accident, allowing for a sufficiently realistic behavior. A traffic light regulation only in the area next to the driven vehicle is also included. A complex model for the vehicles involved in traffic accidents has been developed, including multibody components and different collision models. The developed model is then immediately applicable to large scale driving simulators.
