According to loop characteristic of partially urban road network, urban loop-road traffic coordination control system based on the spit-layer parallel cusp catastrophe particle swarm optimization algorithm is proposed. In the system, the area control system is replaced by the loop-road line control system, and the control sub-area is closed loop-road in road network, a three-layer stepped distributed construction and the spit-layer parallel cusp catastrophe particle swarm optimization algorithm are established, the cycle, offsets and splits are optimized, and then the preset scheme is formed by cooperative control for different closed loop. The final signal control scheme is ascertained by judgment and choice from system hypothesis surface control rate. The application results indicate the control system can reduce the vehicle delay and the stopping rate effectively in the urban.
