Intersection traffic organization and signal timing dial method for tailgating opposite exit lane left-hand turning

Abstract

The invention discloses an intersection traffic organization and signal timing dial method for tailgating opposite exit lane left-hand turning. According to the method, the problem that the number of left-turn vehicle entrance lanes and the number of left-turn vehicle exit lanes in a signal intersection are not matched is solved, phase position and sequence optimization in signal control is matched, an intersection releasing mode is reorganized, left-turn motor vehicles are made to turn leftwards by occupying the exit lanes, and therefore the left-turn traffic capacity of the intersection is improved. Emptying signal lamps are arranged to empty the queue of a left-turn tailgating motorcade, and the traffic flow conflict of the next conflict phase position is avoided. The left-turn traffic flow traffic efficiency can be effectively improved, the vehicle mean delay of the intersection is overall reduced, and the service level of the intersection is improved.

Description

technical field [0001] The invention belongs to the field of urban road intersection traffic planning and design and traffic control, in particular to a traffic organization and signal timing method for an intersection that turns left on an opposite road to an exit road. Background technique [0002] As a key node in the urban traffic network, intersections play a vital role in the smooth operation of the urban road network in terms of smoothness and safety. The behaviors of conflicts, intersections, diversions, and merging of various traffic flows caused by the turning of traffic flow make the traffic characteristics of intersections more complicated, and intersections often become the key points for smooth urban traffic. The left-turn traffic flow at the intersection is the main factor that creates conflict points. Unreasonable left-turn traffic flow organization will reduce the traffic efficiency at the intersection, cause long delays, cause traffic congestion due to vehi...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problem that the number of left-turning entrances and exits does not match due to the limited size of the existing intersections, the present invention provides a method for traffic organization and signal timing at intersections that turn left on opposite exits

The invention solves the conflict between the left-turning traffic flow and the previous conflicting phase traffic flow through the signal control phase sequence adjustment, and erects the empty signal lamp to avoid conflicting with the next conflicting phase traffic flow
