A study on the framework of urban traffic control system
Dong Guo, Zhiheng Li, Jingyan Song, Yi Zhang · 2004
Based on the complexity of the Urban Traffic Control (UTC) system, this paper presents a new framework of hybrid control system for UTC in which any optimal control strategy can be adopted. By the interface D-S and interface C-S namely cooperation model, the hybrid system of UTC is divided into three layers including digital control loop, discrete event module, and Group Decision-making Support System (GDSS). Using GDSS consisted of central agent and intersection agents, real time control and coordinate control with the characteristics of self-decision, cooperation, and intelligence are realized.
