中文摘要：

针对城市快速路网的匝道调节问题,提出了分布式匝道协调控制策略.首先采用动态图混杂自动机与元胞传输模型相结合的方法建立了快速路网的交通流模型;然后分析了系统的平衡状态集,在此基础上设计了分布式匝道协调控制,使得系统状态渐近收敛到某个平衡状态;最后对北京三环快速路网进行了仿真实验.实验结果验证了控制方案的有效性和可行性.

英文摘要：

To solve the ramp control problem of the urban freeway network,a distributed coordination ramp metering was proposed in this paper. Firstly,based on the combination of dynamic graph hybrid automata with the cell transmission model,a traffic flow model for the freeway network was constructed.Then the equilibrium state sets of the system were derived. On the basis of this,a distributed coordination ramp metering was designed under which the system asymptotically converged to an equilibrium state.Lastly,simulation experiments for Beijing third ring freeway were done and the experimental results show that the proposed control scheme is efficient and feasible.
