Problems solved by technology

[0003] Aiming at the defect that the existing urban traffic signal control is mostly single-point signal control or arterial coordinated control, and lacks regional-based signal control, the purpose of the present invention is to provide a regional traffic control method based on load balancing. According to the change of speed, the urban traffic signal control is controlled by line control and area control respectively, so as to achieve the traffic state of urban traffic area load balance

Embodiment Construction

[0037] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0038] The embodiment of the present invention proposes a method for regional traffic control based on load balancing, including the following steps:

[0039] S1, divide the city into multiple traffic sub-regions;

[0040] In some embodiments, traffic sub-regions can be divided according to administrative properties, land use properties, natural separation (rivers, etc.);

[0041] S2, setting bayonet cameras at intersections to capture the number of vehicles;

[0042] S3, taking the time interval between the adjacent red lights and green lights of the same light group at the same intersection as a cycle, calculate the passing flow of each phase in each cycle;

[0043] S4, for an intersection, the inflow flow of each period of its downstream section is as follows:

[0044] Q 路段驶入 =Q 北右转 +Q 东直行 +Q 南左转

[0045] Among them, Q 路段驶入 For this purpose, the inf...

Abstract

The invention provides a regional traffic control method based on load balancing. The invention calculates the load matching degree of the downstream section of the intersection, and performs line control and area control on the urban traffic signal control according to the change of the load matching degree, and then obtains the load-based A balanced regional control method, so as to achieve a traffic state with balanced load in urban traffic areas. The invention solves the defect of single-point signal control or main line coordination control in the prior art, which lacks regional-based signal control.

Description

technical field [0001] The invention relates to the field of urban traffic control, in particular to a load balancing-based regional traffic control method. Background technique [0002] The control object of regional traffic signal control is the traffic signal of all intersections in a certain area of ​​the city; in the urban road network, the traffic flow of different paths may affect each other, and each intersection in an area does not exist in isolation , to control the signal of a certain intersection, the traffic flow of its adjacent intersection will also change accordingly, and then affect the traffic flow of the whole area. At present, the formulation of regional traffic control schemes is mostly based on experience, lacking the support of dynamic data changes, lacking scientific basis, and unable to cope with sudden changes in regional traffic, and inventing a scientific regional traffic control method in the context of big data It is an inevitable trend to make...
