中文摘要
      在高速公路某路段发生阻塞现象时,Markos Papageorgiou(1990)所建立的交通流模型不能反映这一路段交通流的真实状态;本文给出一个改进的交通流模型,可以克服全部缺陷.在新模型基础上构造了入口匝道最优控制问题,计算机仿真结果表明本文的控制策略在降低入口匝道平均等待时间这一性能上有较好的控制效果.
英文摘要
      The traffic flow model established by Markos Papageorgiou(1990)can not describe the real traffic when congestion happens in a section of a freeway.Aiming at the this limitation an improved traffic flow model is presented,on the basis of which an on-ramp optimal control strategy is constructed.Finally the computer simulation results are given,which show that this control strategy is useful in reducing the average waiting time of on-ramp.
