In order to study the problem of evacuation of traffic flow at dynamic traffic network in emergency,the model of the emergency evacuation based on cell transmission model(CTM)was put forward. Traffic flows were dispersed into single vehicle in order to resolve the mathematical efficiency of large scale network. With the time step method,the routes of traffic vehicle evacuation are closely related to travel time on each link under the condition of emergency. Simulation result shows that the effectiveness of the distribution of evacuation flows in dynamic transportation network under the condition of emergency was improved by the model and the algorithm.
