A system and method for setting the same-phase right turn and pedestrian signals at an isolated intersection

Abstract

The invention discloses a setting system and method for same-phase turn-right and pedestrian signals of an independent intersection. The system comprises an image collection module used for collecting image signals of street-crossing pedestrians in pedestrian standing areas on two sides of a pedestrian crossing and transmitting the signals to an image processing module; the image processing module used for transmitting a maximum value of the number of pedestrians waiting to cross the street to a traffic signal controller; a vehicle detector used for transmitting the number of vehicles waiting to turn right to the traffic signal controller and simultaneously collecting a newly-added number of the vehicles turning right in real time when a turn-right signal lamp is green; the traffic signal controller used for calculating a pedestrian street-crossing signal lamp green time Gp and a turn-right vehicle signal lamp green time TR and then transmitting signal control instructions to the traffic signal controller; and a signal controller used for controlling the time of the signal lamps for street-crossing pedestrians and turn-right vehicles. By adopting the setting system and method, the high-speed passing of vehicles and pedestrians at the independent intersection is realized.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a system and method for setting right-turn and pedestrian signals in the same phase at an isolated intersection. Background technique [0002] At present, the composition of urban traffic in my country is complex. Due to the dense flow of people, mutual interference has a great impact on the traffic capacity of motor vehicles, which has become one of the main causes of urban traffic problems. On the one hand, the interweaving and conflict phenomenon of mixed traffic is prominently manifested in urban intersections, which greatly reduces the service capability of the intersection as a node of the urban transportation network, and the previous research on the intersection mostly focuses on the conflict of left-turn motor vehicles. , and there are few studies on the conflict analysis between right-turning vehicles and pedestrians. On the other hand, most right-turn lanes...

AI Technical Summary

Problems solved by technology

If pedestrians crossing the street and right-turning vehicles in the same phase are released at the same time, when the pedestrian flow is large, pedestrians pass through the conflict zone continuously, resulting in less crossing gaps for right-turning vehicles and increased delays for right-turning vehicles; Delays to transfer vehicles further increased

Due to the long waiting time of right-turning motor vehicles, it is easy to cause the driver to feel anxious and forcefully cross the pedestrian flow, which brings hidden dangers to pedestrian safety
