Cellar Automaton Model for Railway Transportation Safety System

The railway transportation safety, system is a complex dynamic system with spatio-temporal characteristics. Taking railway line section as the research object, we propose a new cellular automation (CA) model -- a Safety System Model for Railway (SSM-R)- to simulate the railway safety. In the proposed CA model, we consider a railway line section as a cell and the neighbouring sections as the neighbors, and emphasize particularly on the transition rules including train speed limit rules, train update rules, Signal update rules, block section rules, etc. Then a simulation experiment is carried out with ArcGIS Engine 9.1 and Dot Net, the results show that the model can interpret the evolutional law of the railway transportation safety system.
