摘　　要：近年来交通事故数量逐渐攀升,无信号灯路口的人车事故尤其严重。首先,基于行人、车辆在路口的穿插延误支付、碰撞风险支付,建立人车通行的博弈模型,给予双方合理的优先通行决策;进一步地,在此基础上引入驾驶员的交通奖罚支付,改进博弈模型,并通过实例进行对比分析,改进后的博弈模型增加了车辆的让行率,更有利于道路交通安全;此外,改进传统的病毒传播模型,分析交通参与者的违章心理,通过数值模拟仿真,证明了违章处罚的必要性。为今后过街行人与车辆避撞系统的开发提供了理论上的参考。Traffic accidents have risen in recent years, especially in the case of traffic accidents without signal intersec- tion. A pedestrian and vehicle prevailing game model was established based on the delay and the risk payoff of the pede- strian and the vehicle at the intersection, which could give pedestrians and vehicles a reasonable priority prevailing deci- sion. Moreover, an improved game model was established on the basis of the introduction of the driver＇s reward and fine payoff. Practices proved that the improved model could increase the pass rate of pedestrian, which was more conducive to road traffic safety. In addition, the traditional virus transmission model was improved to analyze the psychology of traffic participants, which proved the necessity of illegal punishment by numerical simulation. The research provides a theoretical reference for the future development of pedestrian and vehicle collision avoidance system.
