Abstract: In order to improve efficiency of large-scale evacuation of people in cities after emergencies, and to reduce casualties and property losses, a multi-mode coordinated evacuation strategy was proposed considering the heterogeneity of disaster victims' mobility and different time window restrictions. Then, an optimized emergency evacuation dispatching model was developed with the goal of minimizing total evacuation time and total loss. Finally, ant colony algorithm was used to solve the problem, and the model's rationality and the algorithm's feasibility were verified based on real case analysis. The results show that the model can converge quickly through algorithm solving, and the model has a certain degree of stability. Moreover, adoption of multi-mode cooperative evacuation for different types of victims is more consistent with actual situation and can form an efficient emergency evacuation scheduling plan.
