中文摘要: 日益拥堵的交通问题严重影响了城市的经济建设和运行效率,因此城市交通网络拥塞时空特性及疏导方法研究已经成为目前国内外学术界共同关注的热点问题之一。本项目针对复杂交通动态系统,将复杂网络理论、牵制控制和海量交通数据进行结合研究,利用特定牵制、自适应局部疏导和预测反馈诱导策略,设计智能疏导调节控制方法,着重解决交通网络发生局部道路拥塞情况下,交通网络的稳定运行问题。充分考虑个别道路拥塞给整个交通网络带来的负面效应,建立时变动态交通网络拓扑结构模型。给出引起道路拥塞的车辆长度临界值,对达到临界值的路段采用负值加权的定义方式,利用含有负权的网络拓扑矩阵研究交通网络中车流量的无限累积对网络稳定性的影响。针对网络拥塞情况,设计主动牵制疏导策略,实现交通网络在期待时间内恢复畅通。从驾驶者角度出发,建立被动诱导的智能调控策略。本项目的研究将为缓解交通网络拥堵提供新的视角和方法。

英文摘要: Since increasing traffic problems affect the city's economic construction and the operating efficiency, the congestion spatio-temporal characteristics and control methods on urban traffic network have become one of subjects collectively focused by domestic and overseas academe.Aiming at complex dynamic traffic system,the project designs intelligent control methods which include special pinning control, adaptive local control strategy and prediction feedback induction strategy,on the basis of the complex network theory,pinning control and massive amount traffic data information. This project focus on solving the stable operation of the transportation network in case of transport local congestion. Fully consider the negative effects of individual road congestion to the entire transport network,the time-varying dynamic traffic network topology model is established. Using the network topology structure matrix with negative weighted studies the effect of the unlimited cumulative vehicles on the stability of traffic network. Through the design active leading strategy realizes transportation network to restore the smooth flow in the expect time. Taking into account the drivers, the passive induced intelligent control strategy is build. The results of this project will provide a new view and approach for alleviating tra
