Embodiment

[0039] In this embodiment, a regional traffic signal control method based on arterial coordination priority, its flow chart is as follows figure 1 shown; the area is an urban road traffic area including several consecutive adjacent intersections, such as figure 2 shown;

[0040] The control method includes the following steps:

[0041] 1. Determine the main road composed of several consecutive intersections in the area;

[0042] 2. Select different phase configuration schemes for each intersection in the area according to the characteristics of the intersection;

[0043] 3. Perform phase difference optimization on the intersections of main roads and non-arterial roads in the area in turn;

[0044] 4. According to the optimization sequence of the phase difference of intersections in the area and the phase scheme of each intersection configuration, the phase green light start time of each intersection is determined in turn, and the regional traffic signal timing is completed...

Abstract

The invention relates to a regional traffic signal control method based on arterial road coordination priority. The regional traffic signal control method based on the arterial road coordination priority solves the problem that in the prior art, a regional traffic control method is not suitable for a road traffic facility present situation of Chinese cities. The regional traffic signal control method based on the arterial road coordination priority comprises the following steps that an arterial road of a region is guaranteed, different phase position allocation schemes are respectively selected for road crossings in the region according to characteristics of the road crossings, arterial road and non-arterial-road crossings are sequentially conducted phase difference optimizing, starting time of phase position green lights of the road crossings are sequentially guaranteed, and traffic signal timing of the region is completed. The regional traffic signal control method based on the arterial road coordination priority has the advantages that optimizing of a complex regional traffic face control system is transformed to optimizing of a linear control system, complexity of regional traffic signal optimizing is reduced, the efficiency of regional traffic signal controlling is greatly improved, the arterial road of a big traffic flow in the region is considered in a key mode, and a primary and secondary distinction optimization order enables the whole regional traffic to obtain the optimal controlling effect.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a regional traffic signal control method based on arterial road coordination priority. Background technique [0002] In order to solve the increasingly serious problem of urban traffic congestion, urban traffic managers and related researchers have proposed many solutions, the most direct of which is to solve the problem by building more roads in the city. However, due to the limitation of urban space capacity, this method is more and more difficult to apply in modern cities. With the development of various technologies such as information technology, communication technology, control technology, sensor technology and system integration technology, intelligent traffic control technology has attracted more and more attention from city managers, and has achieved many beneficial results in many cities. For intelligent traffic control technology, traffic signal contro...
