| 摘要: |
| 在Nagel-Schreckenberg交通流模型中,用速度负补偿机制代替原有的随机减速机制,建立公路隧道交通的一维元胞自动机交通流模型,并进行数值模拟及模型解析.数值模拟结果显示,模型的最大流量点对应的平均速度低于系统的极限速度,适当调节相关参数可以极大限度提高公路隧道通行能力.模型的理论解析与数值模拟结果相一致. |

| 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. |
