Research on Setting Method of Gate Fence at Signalized Intersection Based on PLC Technology

摘要

The phenomenon of pedestrians and non-motor vehicles running red lights at signalized intersections of urban roads is common, which often causes traffic accidents and serious casualties. So far, there is no effective way to solve this problem. In this paper, based on PLC technology, the setting method of gate fence at signalized intersection was studied. Combined with the traffic condition and geometric characteristics of the intersection, the form design, location, and opening time of the fence were determined. TIA V13 SP1 PLC programming software was used to write program section to realize the cooperative control of the gate fence and the traffic light. The effect of the fence and attitudes of residents were analyzed. The research showed that the gate fence had the advantages of convenient setting, easy popularization, and high recognition, which could provide new ideas and methods for the management of signalized intersections.
