Intersection two-phase signal control and canalization method

Abstract

The invention discloses an intersection two-phase signal control and canalization method comprising the following steps: arranging a straight-on traffic passing lane and a right-turn traffic passing lane on each road of the intersection in an entrance lane direction; arranging a turn-round lane before an immutable section of each road of the intersection in the entrance lane direction, arranging a central isolation belt or a widened straight-on lane on each road of the intersection in an exit direction, wherein the widened straight-on lane only allows left-turn traffic in a left side entrance lane direction to line up and wait. When vehicle enters the intersection, the left-turn vehicle takes a right turn with right-turn traffic on a right-turn lane, and the left-turn vehicle enters the straight-on lane, only allowing the left-turn traffic to line up and wait, through the turn-round lane, thus realizing left-turn of the vehicle. The method only needs two phase to effectively solve the bad influences of the intersection left-turn traffic against an intersection signal timing plan, thus providing very effectively improving effects for enhancing intersection passing efficiency, and improving time and space resource utilization.

Description

technical field [0001] The invention relates to the field of urban road traffic, in particular to a two-phase signal control and channelization method at an intersection. Background technique [0002] As urban traffic congestion becomes more and more serious, urban intersections are the bottleneck of the entire urban traffic network, and traffic conflicts at intersections are the cause of intersection bottlenecks. Although the interchange bridge can well solve the contradiction between the intersection conflict and traffic efficiency, it can ensure the traffic efficiency of the intersection while eliminating the traffic flow conflict at the intersection; The high disadvantages are not suitable for general urban road intersections. Generally, the intersection of intersections mainly adopts signal control. Due to the existence of left-turn traffic flow in all directions at the intersection, the signal control scheme of the intersection needs to set the corresponding left-turn...

Although the interchange bridge can well solve the contradiction between the intersection conflict and traffic efficiency, it can ensure the traffic efficiency of the intersection while eliminating the traffic flow conflict at the intersection; however, the interchange bridge has a large area and high cost High disadvantages, not suitable for general urban road intersections

Generally, the intersection of intersections mainly adopts signal control. Due to the existence of left-turn traffic in all directions at the intersection, the signal control scheme of the intersection needs to set the corresponding left-turn phase, which seriously hinders the improvement and reduction of the signal control efficiency of the intersection. The utilization efficiency of time and space resources at the intersection
