Design and development of urban intelligent traffic signal control system

An intelligent traffic signal control system was developed in order to solve the problem of urban road congestion signal control. Based on ARM7, a main control board design scheme of intelligent traffic signal controller was proposed by using S3C44B0X processor. The signal software design was completed based on Clinux operating system. An urban traffic control center software was developed based on the component design by using UDP protocol and ethernet networking system. A multi population genetic algorithm for multi coding common control was proposed to achieve the green ratio optimization. The configured signal controller by GIS technology was used into the central control software in order to obtain the road network topology and other spatial information. Application results show that the new intelligent traffic signal control system has steady performance and easily achieve the optimal control of urban traffic network.
