Problems solved by technology

[0010] The technical problem to be solved by the present invention is to provide a signal control method for variable lanes in order to overcome the defects of road congestion caused by uneven use of lanes at intersections where one-way and two-way traffic organizations converge in the prior art. Lanes, combining the advantages of one-way lanes and two-way lanes, improve the utilization rate of lanes, thereby improving the traffic capacity of intersections and reducing parking queues at intersections

Embodiment Construction

[0040] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0041] Targeted at figure 1 The intersection of the one-way and two-way traffic roads shown and the vehicle flow shown in Table 1 can use variable lanes, so that during the traffic peak, the straight line at the south entrance and the left turn at the west entrance at the intersection of A1 and A2 are eliminated. The phenomenon of secondary queuing exists, which reduces the queuing time of vehicles and improves the traffic efficiency at the intersection of A1 and A2.

[0042] Therefore, the signal control method for variable lanes of the present invention solves the problem of vehicle queuing at intersections A1 and A2 by utilizing the two aspects of variable lanes and traffic signal distribution, and improves traffic efficiency.

[0043]Among them, in terms of utilizing variable lanes,...

Abstract

The invention discloses a signal control method for a variable lane. The signal control method comprises the following steps of: setting a time parameter of each signal lamp and calculating to acquire a forward running clearing time and a reverse running turn-off time; after a green lamp is turned off and a red lamp is turned on, recording first red lamp turn-on time in real time; detecting whether the red lamp turn-on time is greater than or equal to the forward running clearing time, repeating the detection step if a detection result is that the red lamp turn-on time is smaller than the forward running clearing time, and turning on a variable sign if the red lamp turn-on time is greater than or equal to the forward running clearing time; turning off the red lamp, turning on the green lamp and recording green lamp turn-on time in real time after the time for converting the signal lamp is up; and detecting whether the green lamp turn-on time is greater than or equal to the reverse running turn-off time, repeating the detection step if the detection result is that the green lamp turn-on time is not greater than or equal to the reverse running turn-off time, and turning off the variable sign if the green lamp turn-on time is greater than or equal to the reverse running turn-off time. By using the variable lane, the aims of fully utilizing an intersection lane, improving traffic capacity and reducing intersection parking, queuing and delay are fulfilled.

Description

technical field [0001] The invention relates to a signal control method of a lane, in particular to a signal control method of a variable lane. Background technique [0002] One-way traffic refers to road traffic that only allows vehicles to travel in one direction. This is a common traffic management measure. Now one-way traffic is a common traffic management method used by many central cities to alleviate urban traffic congestion. One-way traffic organization can reduce the number of vehicle conflict points at intersections, thereby reducing traffic accidents, simplifying traffic organization to a certain extent, and improving traffic. condition. Experience at home and abroad shows that one-way traffic has a very obvious effect in improving the traffic capacity of the road network, increasing the speed of vehicles and reducing traffic accidents. [0003] Foreign countries began to adopt one-way traffic as early as 1906. There are more than 1,400 streets in Paris, France...
