摘要
为了解决交叉口信号过渡期间行人与车辆常因路权不明确而产生冲突导致交通事故的问题,设计基于车路协同的行人过街主动安全预警系统;采用模块化设计方案,将该系统分为检测模块、控制模块、预警模块及无线通信模块;该系统检测行人和车辆的位置与速度,并对冲突情况进行判别,针对不同情况,执行相应的预警方案;该系统通过语音提示桩对行人进行预警,通过智能斑马线的不同颜色显示,对行人和车辆进行双向预警;在对停车视距模型和行人过街安全心理模型进行改进的基础上,提出考虑人车特性的车辆安全制动距离模型。结果表明:所提出的模型将多种因素协同耦合,考虑了车辆大小和类型对行人心理的影响,具有安全性和有效性;所设计的系统从理论和技术2个方面解决了行人过街安全问题。
To solve the traffic accidents caused by conflicts between pedestrians and vehicles due to unclear right of way during signal transitions at intersections,an active safety warning system for pedestrian crossing based on vehicle infrastructure cooperation was designed.The system was divided into a detection module,a control module,a warning module,and a wireless communication module by using a modular design scheme.The system detected position and speed of pedestrians and vehicles,discriminated conflict situations,and executed corresponding warning schemes for different situations.The system gave warning to pedestrians through voice prompting piles,and gave two-way warning to pedestrians and vehicles through different color display of intelligent zebra crossings.Based on the improvement of stopping sight distance model and pedestrian crossing safety psychological model,a vehicle safety braking distance model considering human-vehicle characteristics was proposed.The results show that the proposed model couples multiple factors synergistically and considers the influence of vehicle size and type on pedestrian psychology,which is safe and effective.The designed system solves the problem of pedestrian crossing safety from both theoretical and technical aspects.
