| Abstract: | Urban traffic control system is the most effective means to deal with the problem of road congestion,and the traffic signal control system is its main part.In order to increase the urban traffic efficiency in middle and small cities,the concept of remote control and intelligent control for traffic signal is developed.Based on the big-city central traffic control system and VPN,the paper suggests to develop the communication protocol compatible for many kinds of intelligent traffic control systems,and to adopt a remote net time-delay compensation for the system and data queue buffering system,so as to remote manage the middle and small urban traffic signal control system.It also encourages the popularization and application of the advanced traffic control technique with low cost,providing new methods and thoughts for the development of intelligent traffic in middle and small cities. |
