A scientific and effective emergency evacuation plan plays an important role in improving the event reaction ability of the urban traffic system, as well as, saves rescue time and reduces property losses. Evacuation route construction and network distribution in each network junction are vital for evacuation planning problems. An optimal objective based on the shortest emergency time is established and the optimal solution is acquired using the Pontryagin minimum principle. The evacuation route construction algorithm and traffic flow assignment algorithm in each junction are employed to deliver the traffic flow in the evacuation area to a safe region rapidly and safely. The idea of feedback is introduced in the execution using real-time information to adjust and update the evacuation plan. The simulation result shows that the proposed model and algorithm can be effectively carried out in an emergency evacuation.
