Multi-agent traffic signal control system

Abstract

A multi-agent traffic signal control system solves the problem that an intersection control mode in the prior art cannot be optimal in practical application and lacks fine coping capacity for sharp change. The multi-agent traffic signal control system is characterized by comprising a first signal lamp to an n signal lamp, a first wireless vehicle sensor to an n wireless vehicle sensor, a first intelligent signal machine to an n intelligent signal machine, a GPRS (general packet radio service), an MAS (mobile agent server), an intelligent traffic signal control service platform and an intelligent traffic database, and a multi-agent traffic control model with a four-layer structure is arranged inside the intelligent traffic signal control service platform. The multi-agent traffic signal control system has the advantages that agents can be implemented by both hardware and software, the wireless intelligent signal machines serve as wireless sensor nodes for collecting traffic information, traffic signal control intelligence and networking are realized, different intersection control modes are adopted in different time periods, specific time periods can be reset or modified according to specific areas or traffic flow by the intelligent signal machines, traffic control is reasonable, and the pressure of a traffic intersection is relieved.

Description

technical field [0001] The invention belongs to an electronic information system, in particular 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 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 complete the fuzzy increase or decrease of traffic signal control time according to the random traffic flow; The traffic lights at each intersection are delayed by a certain amount (phase difference) to ensure the smooth flow of vehicles; the night mode can be used at night when the traffic flow is the least, and only yellow lights are used to warn drivers to reduce power and time consumption; The emergency stop ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies and defects of the prior art, and solve the problem of typical nonlinear, dynamic time-varying and It is very difficult to establish an accurate mathematical model for uncertain and complex urban traffic systems; integrate fuzzy control mode, green wave mode, night mode and emergency stop mode, and use different control modes at different times to achieve traffic Rationalization of control to actually relieve the pressure of traffic intersections
