【摘要】 城市道路信号交叉口行人及非机动车闯红灯现象普遍,往往造成交通事故且伤亡严重。针对该问题,目前尚缺乏有效的解决方案,基于PLC技术对信号交叉口处道闸栅栏设置方法进行研究。结合交叉口的交通状况和几何特征,确定栅栏形式设计、设置地点以及开启时间。利用PLC编程软件TIA V13 SP1编写各项程序段,实现道闸栅栏与信号灯的协同控制。对交叉口设置道闸栅栏的效果和市民接受程度进行了调查分析。研究表明,道闸栅栏设置具有设置方便、容易普及、效果好、认可度高等优势,可以为信号交叉口的管理提供新思路和新方法。更多还原

【Abstract】 It is common for pedestrians and non-motor vehicles to run red lights at urban road signal intersections,which often leads to traffic accidents and serious casualties.Aiming at this problem,there is still no effective solution at present.Based on PLC technology,this paper studied the setting method of the gate fence at the signal intersection.Based on the traffic conditions and geometric characteristics of the intersection,the form design,location and opening time of the fence were determined.PLC programming software TIA V13 SP1 was used to write each program segment to realize the cooperative control of gate barrier and signal lamp.This paper investigated and analyzed the effect and public acceptance degree of installing gate fence at intersections.The research showed that the establishment of gate fence had the advantages of convenient setting,easy popularization,good effect and high recognition,which can provide new ideas and new methods for the management of signalized intersections.更多还原
