Cellular Automaton Model and Simulation of Highway Tunnel Traffic
摘要
Abstract
Based on the Nagel-Schreckenberg traffic flow model. A one-dimension cellular automaton traffic flow model for highway tunnel traffic is established via using negative compensation of velocity as a substitute for stochastic deceleration. Followed by computer simulating and model analysis, the results show that the average speed occurring at the maximum flow point of the model is lower than the speed limit of the system. The capacity of the highway tunnel can be improved greatly by appropriate adjusting the relevant parameters. The theoretical analysis is in agreement with the results obtained from numerical simulation.关键词
