TCP, a traffic signal control algorithm based on knowledge and its simulation using RTE

A traffic signal control algorithm based on the knowledge of traffic engineers, named as TCP (time to change phase) is put forward in this paper. The TCP algorithm is implemented and evaluated through microscopic traffic flow simulation software TSIS (traffic simulation integrated system). The measurements of effectiveness (MOEs) of TCP, fixed-time and actuated control are compared with each other. The simulation results show that TCP algorithm gets better MOEs. Furthermore, when a parameter of TCP is optimized and even better MOEs are gotten. TCP algorithm is simple and practical and also has some characteristics of intelligence and robustness. How to improve TCP algorithm and develop traffic signal control system based on TCP algorithm are also outlined as future work.
