Embodiment

[0037] Embodiment: The present invention provides a traffic green wave coordinated control technology for coordinated optimization of tidal lanes and direction-changing lanes, comprising the following steps:

[0038] Step 1: Determine whether the conditions for setting up tidal lanes are met:

[0039] (1) In my country, road congestion and service levels are generally divided into four levels based on the saturation value: 1) First-level service level: V / C is 0-0.6, the road traffic is smooth, and the service level is very good; 2) Secondary service level: V / C is 0.6-0.8, the traffic condition is slightly congested, and the service level is better; 3) Third level service level: V / C is 0.8, the traffic congestion state, and the service level is poor; 4) Fourth level Service level: V / C is 1.0, showing serious congestion, and the service level is the worst. V / C is greater than or equal to 0.8, which meets the setting of tidal lanes.

[0040] (2) The coefficient of unbalanced traff...

Abstract

The invention belongs to the technical field of traffic signal control and discloses a traffic green wave coordinated control technology for synergistic optimization of tidal lanes and direction-changing lanes, including the following steps: Step 1: judging whether the conditions for setting tidal lanes are met: The value divides the road congestion degree and service level into four grades and the unbalanced flow distribution coefficient: judge whether the service level is above three grades and the direction distribution unbalanced coefficient is >2/3. Step 2: Combine tidal lanes with variable traffic, and set up straight-left and straight-going traffic at the entrance of tidal lanes. When changing the direction of tidal lanes, set a 5-minute clearing time; In wave coordination, a half-period green wave coordination is proposed.

Description

technical field [0001] The invention relates to a traffic green wave coordinated control technology, in particular to a traffic green wave coordinated control technology for coordinated optimization of tidal lanes and direction-changing lanes, and belongs to the technical field of traffic signal control. Background technique [0002] Affected by the existing urban structure, the separation of jobs and residences, and more and more private vehicles, the traffic flow is obviously tidal, and the traffic flow of vehicles entering and leaving the city is seriously congested in the morning and evening. Therefore, the concept of "tidal lane" is introduced. Tidal lanes are lanes based on the different conditions of traffic flow in the morning and evening peak hours. The intersection guide lane indicates that the direction of the vehicle can be changed according to the needs of traffic management. The realization of the lane can be realized by the traffic police according to the on-s...
