Abstract
For speed-limited sections of railway traffic in the four-aspect fixed-block system, we propose a cellular automata model to simulate the traffic flow to analyze how the length of speed-limited section, train time interval and the speed-limit value affect the traffic flow. The simulation results demonstrate that the decrease of the length of speed-limited section, the moderate increase of train time interval and the increase of the speed-limit value can improve the green light runtime of the trains.
