%X Under accident conditions, we propose a total integrated control strategy for the urban expressway networks, by making use of the ramp control and the route guidance. This strategy has a non-linear optimal model with the ramp metering and the splitting proportion as the controlled variables. It also takes into account the accidental traffic characteristics on the expressway. Based on the particle-swarm-optimization, we present a new numerical solution algorithm for this strategy. With a relatively simple network as example, we discuss the accidental impacts on the system performance under different field scenarios. The simulation results indicate that the total integrated strategy reduces the traffic retardation caused by the accident.
