摘要
混合交通流的表现之一是行人交通需求较大,尤其是路段行人过街不但存在安全隐患,还影响交通流的正常运行。目前,应用路段行人过街的专用交通信号控制智能化程度不高,尤其是交通参与方的检测能力不足。因此,针对该问题,深入分析行人过街规律,设计智能行人过街交通信号控制器并研究行人过街优化控制策略,并进行实际场景的测试和验证。结果表明,所研发的行人过街交通信号控制器和控制策略能有效减少行人以及车辆的违法行为发生,保证行人的过街安全并维护交通流的通畅。
One of the performance of mixed traffic flow is the large demand for pedestrian traffic,especially when pedestrians cross the road section,it not only has safety hazards,but also affects the normal operation of traffic flow.At present,the application of special traffic signal control for pedestrians crossing the street is not very intelligent,especially the detection ability of traffic participants is insufficient.Therefore,in response to this problem,the rules of pedestrian crossing are analyzed in depth,the intelligent pedestrian crossing traffic signal controller is designed,and the optimal control strategy for pedestrian crossing is studied,and the actual scene is tested and verified.The results show that the developed pedestrian crossing traffic signal controller and control strategy can effectively reduce the occurrence of illegal activities by pedestrians and vehicles,ensure the safety of pedestrians crossing the street and maintain the smooth flow of traffic.
