发布时间：2018-11-14 09:07
【摘要】：辅路平交口与快速路入口间距的大小不仅影响辅路平交口和主路入口布设地点的选择,也对交通安全有重要影响。发达国家的一些大城市已经建成相当完善的快速路系统,而我国正处在起步阶段,对于快速路的系统研究也才刚刚起步,理论与实践有待进一步积累。本文借鉴国内外快速路研究理论与实践成果,提出了辅路平交口与快速路入口间距的研究,对我国快速路设计、建设、管理具有一定的技术参考。论文对辅路平交口与快速路入口间距作了定义。分析了最小间距的各个组成部分和影响间距大小的众多因素,在考虑对驾驶员最不利情况的基础之上,运用车道变换理论及可接受间隙理论,在满足车辆在该路段上的行驶需求的基础之上,建立了辅路平交口与快速路入口最小间距的计算模型,并给出最小间距的推荐值。参照美国《道路通行能力手册》和我国《城市道路工程设计规范》关于服务水平的划分标准,以车流密度作为评价指标,把目标服务水平下的最大服务交通量作为交通仿真交通量的标定值,运用VISSIM对辅路平交口与快速路入口最小间距推荐值进行仿真验证。确定了仿真验证的操作过程,利用实验输出成果验证辅路平交口与快速路入口最小间距推荐值的合理性,最后得出既满足车辆行驶需求又满足目标服务水平要求的最小间距推荐值。对当前城市中已存的小间距路段,从交通安全、行车舒适性角度出发,针对性的提出了一系列设计对策和交通管制对策。论文的研究成果为快速路与沿线道路系统衔接控制提供了技术支持。
[Abstract]:The distance between the parallel junction of the auxiliary road and the entrance of the expressway not only affects the choice of the location of the horizontal junction of the auxiliary road and the entrance of the main road, but also has an important impact on the traffic safety. Some big cities in developed countries have already built quite perfect expressway system, but our country is in the initial stage, the system research of expressway is just beginning, the theory and practice need to be further accumulated. Based on the theory and practice of expressway research at home and abroad, this paper puts forward the research on the distance between the parallel intersection of the auxiliary road and the entrance of the expressway, which has a certain technical reference for the design, construction and management of the expressway in China. In this paper, the distance between the parallel intersection of the auxiliary road and the entrance of the expressway is defined. In this paper, the components of minimum spacing and many factors influencing the distance are analyzed. On the basis of considering the most disadvantageous situation to the driver, the theory of lane shift and acceptable clearance are used. On the basis of satisfying the requirements of the vehicle on the road section, the model of calculating the minimum distance between the parallel intersection of the auxiliary road and the entrance of the expressway is established, and the recommended value of the minimum distance is given. Referring to the United States Manual of Road capacity and the criteria for the classification of service levels in China's Urban Road Engineering Design Code, the vehicle flow density is taken as the evaluation index. The maximum service traffic volume at the target service level is taken as the calibration value of traffic simulation traffic volume, and the minimum distance between the auxiliary road intersection and the expressway entrance is simulated and verified by VISSIM. The operation process of simulation verification is determined, and the rationality of the recommended minimum distance between the parallel intersection of the auxiliary road and the entrance of the expressway is verified by the experimental output results. Finally, the minimum distance recommended value is obtained to satisfy both the vehicle driving demand and the target service level. From the point of view of traffic safety and traffic comfort, this paper puts forward a series of design countermeasures and traffic control countermeasures for the existing small spaced road sections in cities. The research results provide technical support for the link control between expressway and road system.
