| 中文摘要 |
| 针对城市区域交通控制问题,提出了一种基于D-S证据理论的实时协调控制方法.在交通调查基础上,依据交通量将区域交通状况分为若干类;采用交通分析软件对每一类的典型交通量数据进行仿真分析,从而获得最优配时方案;系统运行时检测交通量,并采用基于D-S证据理论的模式匹配方法,判断当前交通状况属于哪一模式,于是系统将运行相应的配时方案;与此同时,根据检测的交通量数据,定期更新系统存储的交通模式及其对应的最优配时方案。仿真结果表明本文提出的新方法是可行而有效的. |
| 英文摘要 |
| Dempster-Shafer(D-S) evidence theory based adaptive control method for urban local traffic is proposed.On the basis of traffic investigation urban local traffic conditions are classified into several patterns according to the traffic volume;By using the traffic analysis tool to simulate and analyze every representative traffic volume datum,the best timing plans can be got.When the system runs,it will detect the traffic volume on-line and judge which pattern the current traffic volume condition belongs to by using D-S evidence theory based pattern match method,then runs the corresponding best signal timing plan.At the same time,on the basis of the detected traffic volume,the traffic patterns and their corresponding best signal timing plans will be updated at a fixed period.Simulation results show that the proposed method is feasible and efficacious. |
