چکیده
This paper studies the modeling theories and simulation methods for railway transportation system. The railway transportation system is a typical temporal-spatial dynamic system. Recently the method with temporal-spatial computation characteristics, Cellular Automata, is often used for road traffic flow research, but it’s homogeneity restricting make it impossible to modeling railway transportation system, for the objects can not be divided into cells with same size and same transformation rule in railway transportation system. Based on the research on railway transportation system’s characteristics and Cellular Automata Theory, the Entity Automata model is put forward. Entity Automata divided the objects in railway transportation system into several classes and every class entity has it own characteristics and transformation rule. It inherits the temporal-spatial computation characteristics of Cellular Automata and integrates object-oriented method. Simulation experiment result shows using Entity Automata to model and simulate railway transportation system is feasible.

Currently, road transportation is the main mode of freight transit in Iran and about 90% of freight transit is done through this mode of transportation which is not in line with the transportation policies that based on them 70% of the freight transit should be done through road transportation and 30% of the freight transit should be done through rail transportation. However, Iran's railway net...
