主讲内容简介：
（一）构建了拥堵在网络中的演化动力学模型，基于北京和深圳的实际数据，使用该模型研究了拥堵的扩散规律。发现拥堵具有“易发生、难恢复”的特点，两个城市的平均拥堵消散时间与生长时间的比值是1.7~2，且所识别的拥堵扩散规律具有鲁棒性（即与拥堵尺度的定义无关）。（二）研究拥堵在扩散过程中的路径选择，同样基于北京和深圳的交通数据，也得到一些初步结果，高峰期间瞬时最短路径丰富多样，实时最短路径相比其他路径出行时间更短。（三）介绍一个重大项目的结题验收。

主讲内容简介：
Trip booking and traffic rationing are two travel demand management (TDM) strategies proposed over the last two decades to reduce negative externalities generated by travel demand over available supply or road capacity, and to reduce air pollution. Trip booking allows drivers to reserve certain areas or lanes/segments of roads for their use during specific time periods, while traffic rationing restricts access to urban areas or city centers based on the last digits of license plates during peak hours. However, these strategies have been studied and implemented separately. This paper proposes a novel hybrid strategy of booking cum rationing for efficient and equitable TDM. The strategy can be formulated as a linear programming problem in a general network and can achieve a traffic flow distribution pattern while maintaining fairness, efficiency, and flexibility of individual choices. Simple examples are provided to demonstrate the effectiveness of this hybrid strategy.
