交叉口交通拥挤动态识别模型
摘要交叉口作为道路网重要的节点，连接着多条道路，是交通拥堵的多发性地段。交叉口交通拥堵导致车辆排放大量废弃物，并且大大增加了出行者的出行时间。对交叉口交 通拥堵进行准确的识别，能够尽可能的降低交通拥堵带来的负面影响，提高整个道路系 统的运行效率。因此，对交叉口交通拥堵的识别进行研究具有重大的意义。 75530
本文主要研究内容是：首先，介绍了国内外研究现状，提出交通拥堵的定义，进行 了拥堵分类，总结了拥堵判别指标，以及对交叉口交通拥堵形成原因进行了分析。其次， 在分析总结经典的拥堵识别算法的基础上，提出基于识别单元出入流率的交叉口交通拥 堵识别方法。 最后，运用实际案例对该方法的识别效果进行验证。

Title Dynamic Identification Model of Intersection Traffic Congestion
Abstract Intersections as an important node in the road network, connecting several roads, is multiple lots of traffic jams。 Intersection traffic jams cause the vehicle to emit large quantities of waste, and greatly increased travel time travelers。 Intersection traffic congestion on the accurate identification, as much as possible to reduce the negative impact of traffic congestion caused, improve operational efficiency of the road system。 Therefore, the identification of the intersection traffic congestion study is of great significance。
The main contents of this article are: Firstly, the current research, the proposed definition of traffic congestion, the congestion was classified, summarized the congestion judging indexes, as well as intersection traffic congestion causes were analyzed。 Secondly, based on the analysis summary classic congestion recognition algorithm is proposed based on the flow rate out of the recognition unit Intersection traffic congestion identification method。 Finally, the use of actual cases this method to verify recognition results。
Keywords Intersection traffic congestion Congestion judging indexes Recognition algorithm Identification unit out of the flow rate
