城市路段行人过街辅助系统设计

Design of the Auxiliary System for Pedestrian Crossing Facilities on Urban Roads

摘要: 随着机动车礼让行人规定的贯彻实施，提高了行人过街的安全性，但同时也在一定程度上增加了路段追尾事故发生率，并降低了城市路段的通行效率。针对以上问题，本文设计了城市路段行人过街辅助系统。利用红外检测装置以及压力传感装置检测行人的过街方向以及实时动态，并根据行人的位置变化，准确地为车辆提供分车道预警。设计的系统能够在一定程度上提高行人过街的安全性，预防机动车追尾事故的发生，提高城市交通运行效率。

Abstract: Since the implementation of the regulations about comity pedestrians for vehicles, the security of crossing street for pedestrians has been improved. Meanwhile, the incidence of road rear-end collision has been increased to a certain extent, and the efficiency of crossing has been decreased on the urban road. For the above questions, this paper has designed the auxiliary system for pedestrians crossing the street. This system utilizes the infrared detection devices and the pressure sensing devices to detect pedestrians’ crossing directions and real-time dynamic. It can provide lane warning for vehicles according to the change of pedestrians’ positions accurately. The system designed can improve the security of crossing street for pedestrians, prevent the occurrence of rear-end collisions for vehicles, and enhance the efficiency of urban traffic in some degree.
