【摘要】：近年来,随着我国城镇化建设的全面开展以及经济水平的不断提升,为适应城市发展的需要及改善城市交通运行质量,基础设施建设项目逐渐增多,这些项目在建设过程中,会占用部分现有道路资源进行施工,将加重城市道路设施的交通负荷,对现有交通的运行存在较大的影响,尤其是在中心城区的拥挤道路上占道施工产生的影响就更为显著。为了缓解占道施工带来的交通拥挤和避免由于占道诱发的交通事故,本文以施工区的交通特性分析、交通影响区范围确定为基础,通过对行程时间动态可靠性和路径敏感度的分析建模,旨在建立占道施工影响区的车流均衡诱导模型,以合理的诱导组织交通,缓解由占道施工产生的交通拥堵。本文在参考国内外研究成果的基础上,分析了占道施工区域的交通特征,提出了施工影响区的实际通行能力的计算方法;提出了基于等效通行能力、交叉口转弯交通量比例以及施工项目出行方向系数来确定占道施工交通影响区范围;在分析了行程时间可靠性理论和路径剩余通行能力的基础上,建立了路径动态行程时间可靠度模型和路径敏感度函数模型,并由此结合Logit SUE交通分配模型建立了占道施工影响区车流均衡诱导模型。应用该模型对占道施工影响区交通流进行重新分配,以最大程度降低施工以及相关的交通组织措施对施工影响区交通造成的负面影响。最后,论文以凤天大道占道施工项目为例,选取路网运输效率指数作为评价指标对车流均衡诱导模型的实际应用效果进行了评价,验证了动态行程时间可靠性应用在交通组织中的有效性,该研究推动了交通组织理论研究与实际应用的结合,为占道施工交通组织方案的制定提供了科学的参考。
[Abstract]:In recent years, with the overall development of urbanization and the continuous improvement of economic level, in order to meet the needs of urban development and improve the quality of urban traffic, infrastructure construction projects are gradually increasing. These projects will occupy part of the existing road resources for construction in the construction process, will increase the traffic load of urban road facilities, and have a greater impact on the operation of existing traffic. In order to alleviate the traffic congestion and avoid the traffic accidents caused by the congestion, the impact of the construction on the congested roads in the central urban area is more significant. Based on the analysis of the traffic characteristics of the construction area and the determination of the range of the traffic affected area, the dynamic reliability of travel time and the path sensitivity are analyzed and modeled in this paper. The purpose of this paper is to establish a traffic flow equilibrium guidance model in the affected area of road Occupy construction so as to organize traffic reasonably and alleviate the traffic congestion caused by the construction of the Occupy Road. This paper refers to the research results at home and abroad. The traffic characteristics of the construction area are analyzed, and the calculation method of the actual capacity of the construction affected area is put forward. Based on the equivalent capacity, the ratio of traffic volume at intersection turn and the travel direction coefficient of construction project, the scope of traffic impact area is determined. On the basis of analyzing the theory of travel time reliability and the residual capacity of the path, the dynamic travel time reliability model and the path sensitivity function model are established. Based on the Logit SUE traffic assignment model, a traffic flow equilibrium guidance model is established, which is used to redistribute the traffic flow in the affected area. In order to minimize the construction and related traffic organization measures on the construction of the impact of the negative impact of traffic. Finally, the paper takes Fengtian Avenue construction project as an example. Select the road network transportation efficiency index as the evaluation index to evaluate the actual application effect of the vehicle flow equilibrium guidance model, and verify the validity of dynamic travel time reliability application in traffic organization. The research promotes the combination of theoretical research and practical application of traffic organization, and provides a scientific reference for the formulation of traffic organization scheme in road construction.
