Intelligent and Proactive Traffic Control System:Concept and Experiments

: Traffic control system does not match the increasing requirements of modern urban traffic network with the limitation of traditional traffic information content and collection methods, implementation techniques and optimization models. The latest advances in intelligent transportation systems and Connected Vehicle technologies lay a solid foundation for enhancing the ability of optimization, adaptability, and quick response of traffic signal control system. This paper analyzes the impact of revolution of information, communication, and computation technologies on environment, object, and implementation methods of traffic control system. Then the next generation of traffic control system is featured by safer, faster, greener, and human friendly. The prototype of this intelligent and pro-active traffic signal control systems is designed and implemented as well. The initial test results validated that the proposed system and their supporting information and communication technologies have promising property and a broad prospect.
