| 摘 要： | 以昆明市为例,通过实地调查的方式,分析了城市核心区主干路的交通区域拥塞交通流特性,运用烟羽模型对交通拥塞的时空变化规律进行了定量化分析.定性分析了驾驶员行为特性对道路交通拥塞影响,提出首次交通拥塞与二次交通拥塞的概念,并结合道路状况,借鉴蚁群模型的理论,对首次交通拥塞到二次交通拥塞演变规律进行了分析,总结出基于驾驶员行为特性的演变规律.

| Abstract: | Taking Kunming as an example,analyzes the traffic flow characteristics of traffic congestion at trunk road of urban core area through the field investigation and makes quantitative analysis on the space-time change law of traffic congestion using plume model.A qualitative analysis of the influence of driver’s behavior to the road traffic congestion,and put forward the concept of the first time traffic congestion and the second time traffic congestion.Combining with the condition of the road,and using the ant colony optimization model theory,analyzed the evolution from the first time traffic congest to the second time traffic congestion in the traffic congest regional,and summarized this evolution rule based on the driver’s behavior. |

| Keywords: | urban core area trunk road temporal and spatial variation plume model second time traffic congestion |
