Abstract

The invention provides a dynamic traffic signal control method for an intersection for left-turning motor vehicles to turn by occupying a right lane, relates to a city intersection traffic signal control method, and aims at solving the technical problems that the prior art is incapable of thoroughly utilizing the internal space resources of the intersection and not high in safety level and traffic capacity, a traditional traffic signal control method is not applicable to an intersection left-turning motor vehicle management method for two-stage turning of left-turning motor vehicles occupying the right lane, and the like. The dynamic traffic signal control method for the intersection for left-turning motor vehicles to turn by occupying the right lane comprises the implementation procedures of step 1, designing a signal intersection channelization scheme, step 2, setting traffic signal phases and a phase sequence according to the signal intersection channelization scheme designed in the step 1, step 3, arranging induction coil detectors, and step 4, designing an induction signal control logic. The method is used for the dynamic traffic signal control at a plane intersection for the intersection for left-turning motor vehicles to turn by occupying the right lane.

Description

technical field [0001] The invention relates to a traffic signal control method at an urban intersection. Background technique [0002] The signalized intersection is the "throat" of the urban road network, and its traffic signal control benefits directly affect the operation status of the road network traffic flow. The left-turning vehicle has always been a difficult point in signal control at intersections. It is not only the main factor that creates conflict points, but also has a great impact on the traffic of oncoming straight-going vehicles. Especially in recent years, my country has begun to implement the "Bus Priority Strategy". Major cities have built BRT systems and set up two-way bus lanes in the center of urban arterial roads, which further compressed the space resources available to ordinary motor vehicles at signalized intersections, resulting in many It is difficult to set a special left-turn entrance lane at an intersection, and it is impossible to set a spec...
