Urban road traffic network control method and system

Abstract

The present invention provides an urban road traffic network control method and system. The urban road traffic network control method comprises: a. a control area is divided into a plurality of intersection subareas, an intersection of each subarea is respectively provided with an intersection agent used for detection and control of traffic information; b. correlations of the plurality of intersections are calculated in each subarea to determine an intersection agent having the highest correlation as a main agent of the subareas, and the main agent is used for gathering and uploading all the traffic information in the subarea; and c. the traffic is controlled and induced according to the gathered traffic information. According to the invention, intersections, road sections, vehicles and pedestrians are constructed to be agents, and the road traffic system is improved through the induction of travel behaviors of the vehicles and the pedestrians, so that the occurrence of the traffic jam may be avoided and the sojourn time of the vehicles on the road is reduced. Moreover, the traffic flow of each road section in the road network may be reasonably distributed, and the reliability and the stability of the road traffic network control may be ensured.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and system for controlling an urban road traffic network. Background technique [0002] With the development of our country's social economy, people's living standards are improving day by day, and cars have become an essential tool for people to travel. Traffic problems are getting worse. With the rapid development of computer technology, network technology, information technology and control technology, the new development of urban road traffic network control has been caused, and the traffic control has developed from the original traditional control to modern urban traffic control. However, compared with the rapid expansion of cities and the rapid increase of vehicles, the demand for urban roads is close to saturation. The traffic control system in my country is still lagging behind. The construction speed of urban roads is far behind the growth rate of the...

Problems solved by technology

However, compared with the rapid expansion of cities and the rapid increase of vehicles, the demand for urban roads is close to saturation. The traffic control system in my country is still lagging behind. The construction speed of urban roads is far behind the growth rate of the number of cars. It is a bottleneck problem, and the key technologies of the existing traffic control and guidance platforms are almost all in the hands of foreign companies, and the use of their algorithms requires expensive copyright fees
