Title    MTR passengers evacuation simulation based on cellular automata model                                                 

Abstract The urban rail transit system is one of the biggest scales of capital construction, which is of decisive significance to accelerate our socialist economic development. The study of building human evacuation model has been the important aspect now in the city railway transportation researches. Building a simulation model which is based on the passengers’ volume, distribution, density and direction is important to the intelligent decision, control and safe evacuation of the railway transportation service system.

The paper analyzes the passenger flow characteristics of platform、walkway and ladder in the subway; The subway passenger evacuation requirements have been expounded. I have made a simple model about the subway passengers evacuation after the study of CA and done a simulation by using Matlab software, for the instance of Nanjing No.1 xinjiekou transfer channel.

Some evacuation time has been gotted ,and it has great significance for improving the transfer channel and emergency disposal of passenger evacuation .
