【Abstract】 A cellular automaton model for the bottleneck in high speed traffic caused by a bridge is proposed. It takes the initial density apart into six regions. Based on the mean field theory and the results of definitive NS model, the relations of car density of every line are given. The simulation results show that the theoretical model is correct.更多还原
