摘　　要：大型活动时需求激增易引起交通拥挤。本文提出用于评价拥挤应对策略的仿真分析方法。该方法采用宏观交通仿真技术,模拟网络交通流演化过程,分析拥挤成因,以便提出应对策略并验证其有效性。采用GANFreSP仿真系统对一算例路网进行仿真,刻画拥挤发生、传播和消散的过程,并模拟交通系统管理和交通需求管理的拥堵应对策略,给出了路网全局交通状态快照图、交通状态时变轨迹图等可视化结果,及路网总体性能指标。仿真案例表明了该方法在交通控制与管理中的有用性和辅助决策作用。Surging demand when large events was prone to induce traffic congestion. This paper presented a simulation analysis approach to evaluate traffic management strategies. This approach used macroscopic traffic simulation technology to simulate evolution process of traffic flow in network, and analysis the cause of congestion, so as to propose strategies and evaluate their availability. GANFreSP simulation system was used to depict occurrence, propagation, and dissolving of congestion in a simulated freeway network, and simulate the effects of management strategies, and present snapshots of global network state, traffic state trajectories, and overall performance indexes. Research results show that this approach is serviceable and auxiliary in traffic control and management.
