The article builds an evacuation network made of two kinds of districts-fixed district and unfixed district which divide the network into several small evacuation networks according to the flow and location of the exits. Next, based on safety, speed and order as the whole objective i.e. smaller audiences' congestion degree and smaller total evacuation time, the writer sets up improved max entropy model to distribute evacuation flow to each districts, and then produce the programs that simulate the stream of people in these districts and draw out the graphs according to the simulation model. Consequently, handlers may find out bottleneck of lanes and other else dissatisfied parts to supply with appropriate management and improvement by modifying the parameter values, as a result people can go smooth and feel ease.
