On Consensus for Urban Traffic Network System

The signal control problem of urban road traffic network is studied. A CTM-based discrete-time urban road traffic network system model is established. Aiming at the urban traffic network system, the multi-agent consistency idea is applied to the urban traffic network system analysis and control, and the consistency control protocol design method is proposed. Taking the change of the green light duration as the control input, a consistency control protocol is designed using the consistency algorithm of the discrete multi-agent system, the stability of the controlled system is analyzed, and the urban road traffic network is asymptotically consistent stability conditions. The simulation results show that when the stability conditions are met, the method controls the change of the green light time of each link to make the entire system reach asymptotic consistency, that is, the state of all links in the road network is consistent, which verifies the feasibility of the proposed method Sex and effectiveness.
