Multi-agent traffic signal control system

Abstract

The invention relates to a multi-agent traffic signal control system and solves problems that the intersection control mode of the traffic signal control system in the prior art cannot achieve the optimum in practical application and the traffic signal control system lacks good large-change handling capability. The multi-agent traffic signal control system is characterized by comprising first-nth signal lamps, first-nth wireless vehicle sensors, first-nth intelligent annunciators, a general packet radio service (GPRS), a multi-agent system (MAS) service platform, an intelligent traffic signal control service platform and an intelligent traffic database, wherein a four-layer structural multi-agent traffic control model is arranged in the intelligent traffic signal control service platform. The multi-agent traffic signal control system has the advantages that the wireless intelligent annunciators are adopted to serve as wireless sensor nodes to collect traffic information, intelligentization and networking of traffic signal control are achieved, different intersection control modes are adopted at different time intervals, specific time intervals can be reset or modified through the intelligent annunciators according to specific areas or traffic flow, reasonable traffic control is achieved, and traffic intersection pressure can be relieved practically.

Description

Technical field [0001] The invention belongs to an electronic information system, and particularly relates to an intelligent traffic management control system, especially a multi-agent traffic signal control system. Background technique [0002] In the prior art, the intersection control modes of the traffic signal control system include timing control mode, fuzzy control mode, green wave band mode, night mode and emergency stop mode. Among them, the timing control mode is to change the traffic light change time according to the set time; the fuzzy control mode is to intelligently increase and decrease the traffic signal control time according to the random traffic flow; the green wave mode is to change the traffic signal control time during the one-way vehicle peak period. The traffic lights between the intersections are delayed by a certain amount (phase difference) to ensure the smooth flow of vehicles; night mode can be used at night when the traffic volume is minimal, and on...
