Coordinated, Efficient and Optimized Crowd Evacuation in Urban Complexes

With the development of the city, more and more urban complexes which are areas combine leisure, repast, and trade functions have emerged in our daily life. However, as the increasing of people in urban complexes, the danger of security incidents increases. Therefore, how to evacuate the crowd after a security incident as soon as possible has become a crucial issue. Evacuation not only refers to the process of transferring crowd from indoors to outdoors but also transfers the outdoor crowd to safe places by means of transportation, such as taxis, buses, subways and so on. To this end, we establish a human-vehicle collaborative evacuation system(HVCES) in Suzhou Center which is one of the largest and most advanced urban complexes in China. Based on the system, we obtain a safer and optimal vehicles scheduling strategy with heuristic algorithms to reduce the probability of an accident during the evacuation.
