Abstract

The method treats city traffic signal control system as traffic network as each crossing is an agent which has function of information self-collecting and self-processing. The system can realize dynamic decision for traffic signal control at each crossing by relying on network self-organization. The attribute matrix is used to express state information for local and adjacent crossing with using relative bearing for connected crossing. The system is established to be virtual network model with cellular automara features so the self-organized control for traffic signal can be realized by carrying on dynamic migration of crossing signal state under control rule driving.

Description

Technical field:

[0001] The invention relates to a method for self-organized control of urban traffic signals, in particular to a method for self-organized control of urban traffic signals based on cellular automata, and belongs to the technical field of traffic engineering. Background technique:

[0002] Urban traffic signal control is a real-time complex system control problem. Considering the traffic signal control system of the whole city as a network and each intersection as a node in the network, the system has obvious characteristics of integrity, complexity, openness, and large degree of freedom. The complex relationship of signals, traffic flow, road conditions and other factors at adjacent intersections in the system constitutes the macroscopic pattern of urban traffic; the deterioration of the state of local intersections may lead to the crisis of the entire urban traffic system. At the same time, in such a system with a large degree of freedom, there is great un...
