中文摘要：

为缓解施工作业对快速路运营的压力,提出了基于宏观交通流仿真的快速路施工组织方案评价方法,旨在为施工方案决策提供辅助依据。该方法运用宏观交通流仿真对各候选施工方案分别进行仿真和评价,得到较优方案。采用快速路施工组织方案辅助决策系统对沪宁高速上海段施工作业进行了宏观交通流仿真,再现了施工造成的作业区上游路段交通拥挤的发生、传播和消散过程,并仿真不同施工组织方案交通流的时空演变,给出局部路段交通状态时变图和全局交通状态图等可视化仿真结果,以及总体性能评价指标。仿真结果表明,该方法能较好地描述施工作业对快速道路交通流的影响,是施工组织方案评价的有效方法。

英文摘要：

In order to relieve expressway congestion caused by construction,the authors propose an evaluation method of construction organization scheme for expressway based on macroscopic traffic flow simulation,which aims to provide a support for scheme decision of construction organization scheme.The authors use macroscopic traffic flow simulation method to investigate and evaluate candidate construction schemes,and obtain superior scheme.Assistant decision system of construction organization scheme for expressway is designed to simulate expressway construction of Huning Expressway in Shanghai,the process of occurrence,propagation and dissipation of congestion is reappeared,the effects of different construction organization schemes is simulated,and visual simulation results are obtained including trajectories of local traffic state and snapshots of global traffic state,as well as overall performance evaluation indexes.Simulation results show that the method does well in describing expressway traffic flow influenced by construction,and it is effective for evaluating different construction organization schemes.
