介绍中国科技大学复杂系统研究组完成的关于城市交通与交通网络复杂系统的一些研究工作。概述了中科大项目组在交通流问题的4个研究方向所取得的进展,分别是:交通网络的输运和堵塞演化研究;城市交通系统的拓扑与瓶颈结构及堵塞相变;新一代智能车辆应用于多通道选择的各种预测反馈策略的提出和三相交通流理论研究及新的交通流模型的提出。
This article introduced some research work on transportation in cities and the traffic network complex systems completed by the USTC Complex System Research Group. The outline will be presented for the progress obtained by USTC group in the four directions of traffic flow research:the transportation optimization and jamming evolution of traffic networks; the topologic and bottleneck structure of the city traffic systems and the phase transition of traffic jamming; the prediction feedback strategy to select the road from multi pathway for the next generaion of intelligent vehicles;three phase traffic flow theory and the new traffic flow modles.
