Traffic flow capacity increasing control method for comprehensive waiting area at road intersection

Abstract

The invention discloses a traffic flow capacity increasing control method for a comprehensive waiting area at a road intersection, comprising the following steps: S1, adding a comprehensive waiting area, setting a primary stopping line and a secondary stopping line at the end of the comprehensive waiting area, and setting the distance between the primary stopping line and the secondary stopping line as the length of the comprehensive waiting area; and S2, adding a variable information board, pre-signal lamps and an induction coil buried under the road surface to the medial strip of the road opposite the comprehensive waiting area, wherein the pre-signal lamps include a pre-signal red lamp and a pre-signal green lamp, and the pre-signal red lamp goes on 10-12 seconds earlier than an original go-straight or turn-left traffic signal green lamp at the intersection. By adopting the method of the invention, the traffic capacity of the intersection is improved greatly, and the space resources of the intersection are prevented from lying idle.

Description

technical field [0001] The invention relates to a vehicle control method at an urban intersection, in particular to a method for controlling traffic volume increase in a comprehensive waiting area of ​​a road intersection. Background technique [0002] In urban roads, the one-way 4-lane road at the intersection is generally channelized into 5 entrance lanes, 2 left-turn lanes, 2 through lanes, and 1 right-turn lane, usually with a left-turn waiting area, such as figure 1 shown. "Ten" intersections generally adopt four-phase signal control. [0003] Phase one is going straight from north to south, turning left from north to south and entering the left-turn waiting area; phase two is turning left from north to south; phase three is going straight from east to west, turning left from east to west and entering the left-turn waiting area; phase four is turning left from east to west. Therefore, the current situation of traffic flow channelization at road intersections has the f...

AI Technical Summary

Problems solved by technology

Therefore, the intersection congestion is serious, and the existing traffic capacity is difficult to meet the traffic demand

[0008] 2. There is a waste of space at intersections

When passing through vehicles, there are few vehicles on the left-turn lane, and similarly, when leaving-turning vehicles pass, there are few vehicles on the through lane, and the space resources of the intersection are not fully utilized.
