"Windmill" intersection design method

Abstract

The present invention provides an urban road intersection channelization method, specifically relates to a windmill type intersection design method. The method provided by the invention comprises: (1) acquiring intersection information; (2) determining whether the intersection is suitable for adoption of a windmill type signal control intersection; (3) performing the design of a left-turn diverging area; (4) performing a design of a left-turn waiting area; (5) performing a design of a left-turn guidance lane; (6) performing a design of a pedestrian crossing zebra crossing and a going-straight vehicle stop line; (7) performing a design of inducting signals of a left-turn vehicle entering the left-turn waiting area. Through adoption of a novel channelization scheme and a left-turn vehicle induction control of a windmill type intersection, the intersection conflict between the left-turn vehicle and a going-straight vehicle in an opposite direction is converted to the confluence interlacing of the left-turn vehicle and the going-straight vehicle at a side direction, and therefore the average delay of vehicles is reduced, the passage efficiency of the intersection is enhanced, the traffic conflict is decreased, and the safety of the intersection is improved.

Description

technical field [0001] The invention relates to a method for channelizing urban road intersections, specifically a "windmill-type" intersection design method. Background technique [0002] At present, the problem of traffic congestion in my country's cities is becoming more and more serious, and large-scale intersections are the bottleneck nodes in the traffic network. The level of control efficiency of these intersections will be directly related to whether the traffic of the whole city is smooth. For large level intersections, the passage of left-turn motor vehicles has always been a difficult point of control. The passage of left-turn vehicles has a great impact on the through traffic flow and is the main factor of conflicts. In the existing control technology, most of the left-turning vehicles at these intersections will be given a dedicated phase for left-turning alone, but this will cause problems such as increased signal phase, increased signal period, and increased...
