UTCS(Urban Traffic Control System) and UTGS(Urban Traffic Guidance System) are two main subsystems of traffic management system. In this paper, traffic optimal control model and quasi-system optimal dynamic traffic assignment model are used. Then, the dynamic cooperation optimizes the results alternatively until the results are fitted to both UTCS and UTGS. In the process of dynamic cooperation, one guidance cycle consists two close control cycles, using the second control cycle parameters to calculate the next guidance cycle parameters, this cooperation can ensure UTCS and UTGS follow the real-time traffic flow dynamically. It also ensures UTGS strategy continuity and dynamic cooperation of UTCS with UTGS. The simulation result proved that the dynamic cooperation in this paper is practical and feasible. The study provides theory and method guide for real cooperation of UTCS with UTGS application system development.
