【摘要】：随着我国城镇化进程的加快,干线公路发挥的作用越来越大,干线公路交通需求增长迅速,而基础交通设施建设相对缓慢,交通管理水平也相对落后,由此衍生的交通问题也越发尖锐,干线公路交通供需不平衡,交通拥挤问题日渐突显,交通安全性下降,严重时还会导致交通事故的发生。因此,对干线公路交通运行状态进行评价,不仅是研究干线公路交通运行特征规律的关键手段,还有助于发现交通运行不理想的原因,为干线公路管理者制定交通改善政策和措施提供理论支持,甚至可以对其规划设计起到指导作用。本文遵循“总结国内外研究成果—指标体系构建—交通运行状态评价—交通运行状态改善措施分析”的思路,首先,通过资料搜集和对比分析,总结国内外关于交通运行状态的研究现状,提出干线公路交通运行状态评价方面存在的缺陷和不足;其次,从干线公路的交通流量、交通阻断、突发事件三个方面进行评价,选取适用的评价指标,分别构建不同交通运行状态评价指标体系;再次,选取重点监测路段,构建干线公路重点监测路段选取模型,并在此基础上,研究路网的交通运行状态评价过程;最后,针对干线公路交通运行不理想的状态,研究实用可行的改善措施,提高干线公路的运行效率。
[Abstract]:With the acceleration of urbanization in China, trunk roads play a more and more important role. The traffic demand of trunk roads is growing rapidly, while the construction of basic transport facilities is relatively slow, and the level of traffic management is relatively backward. The traffic problems derived from this are becoming more and more acute, the traffic supply and demand of trunk roads are unbalanced, the problem of traffic congestion is becoming more and more prominent, the traffic safety is declining, and when it is serious, it will lead to the occurrence of traffic accidents. Therefore, the evaluation of the traffic running state of the trunk highway is not only the key means to study the characteristics of the traffic operation of the trunk highway, but also helps to find out the causes of the unsatisfactory traffic operation. It can provide theoretical support for highway managers to formulate traffic improvement policies and measures, and even play a guiding role in their planning and design. This paper follows the idea of "summing up the domestic and foreign research achievements-constructing the index system-evaluating the traffic running state-analyzing the measures to improve the traffic running state". Firstly, through collecting and comparing the data, This paper summarizes the current situation of research on traffic operation status at home and abroad, and points out the defects and deficiencies in the evaluation of traffic operation status of trunk roads. Secondly, from three aspects of traffic flow, traffic interruption, emergency evaluation of the trunk highway, select suitable evaluation indicators, respectively build different traffic operation status evaluation index system; Thirdly, select the key monitoring section, construct the selection model of the key monitoring section of the trunk highway, and on this basis, study the evaluation process of the road network traffic running state; Finally, the paper studies practical and feasible improvement measures to improve the running efficiency of trunk highway.
