The Non-Equilibrium Vehicle Evacuation Model of Regional Traffic under Planned Special Events and Its Application to the 2008 Olympic Games

With the development of Chinese economy, more and more large planned special events, such as Olympic Games, Expo, and so on, have been held in many metropolitans, which may bring huge pressures to city´s normal transportation. In this paper, a non-equilibrium vehicle evacuation model at small area under planned special events was set up, and the heuristic algorithm was given in detail. Then, we applied the model and its algorithm to the 2008 Olympic football games in the Tianjin sports centre, and compared with the data obtained by Tianjin traffic administration bureau, such traffic flow assignment results were proved applicable and practicable.
