基于微观模拟的城市快速路交通事故影响评价系统

A Micro-Simulation-based Evaluation System for Thruway Traffic Accidents

城市快速路交通事故所产生的间接影响远远大于事故的直接损失,而其定量数据又很难通过实际的检测设备和测量手段得到,以车辆微观行为模型为基础,采用面向对象的软件设计方法,建立了城市快速路交通事故影响的微观模拟评价系统.在真实模拟车辆行驶状态的基础上,通过设置事故状态和数据探测器,可以全面记录车辆行驶过程中实际检测设备难以采集到的相关数据,从而为事故影响的定量分析奠定了良好的基础.

The indirect effect of thruway traffic accident is greater than direct effect, and it is immeasurable at fiehlwork. Based on vehicle microscopic behavior model, the paper developed the evaluation system for effect of thruway traffic accident by adopting object-oriented software technology. The system can simulate movement of vehicle, state of traffic accident and data detector. It can record every data includinge those immeasurable at fieldwork. Which is the foundation of evaluating effect of thruway traffic accident.
