【摘要】：随着城市化进程不断的推进,北京市城市规模日益扩大,但核心功能区集中在主城区,居住区却向郊区县发展,这种不平衡的关系导致了早晚高峰期间“潮汐式”交通现象尤为严重,这也是本课题来源的重要因素之一。京通快速路作为北京市典型潮汐现象代表路段之一,进行潮汐车道建设和运营方案的研究是具有创新性和前瞻性的。潮汐车道作为解决不对称交通一种重要手段,已经在国内外得到广泛应用,然而将其应用与城市快速路或是高速公路尚无先例。在研究京通快速路潮汐车道的过程中,对晚高峰期间交通流量和行车速度进行调查,通过计算车流量的分布系数和车辆平均形式速度来分析设置潮汐车道的路段,同时建立了可变车道分配优化的数学模型,通过数学方法来印证车道分配的合理性。潮汐车道方案选取长、短两个路段作为对比,分别对其重要的节点、建设方案、出入口、断面方案、技术经济指标等进行分析,综合分析两种方案的风险和问题。运营保障方案是京通快速路潮汐车道项目极为重要的内容。在日常管理上需采用规范的流程来管理启动前准备、启动、关闭潮汐车道等步骤,使整个过程运行顺畅和高效。在应急管理中首先建立组织保障,成立协调组和实施组,其次针对各种可能发生的突发事件制定解决方案,确保不论是交通事故还是其他突发事件都能够从容应对,快速处理。通过对京通快速路潮汐车道的讨论和研究,不只是解决了其本身的建设和运营方面的问题,同时调查中交通流量和行驶速度数据可作为基础数据作为决策依据。再者,对复杂交通地段交通组织和路权的使用处理方法,以及应急抢险和管理方面的原则也能够为其他相关类似城市主干道设置潮汐车道提供借鉴。
[Abstract]:With the development of urbanization, the urban scale of Beijing is expanding day by day, but the core functional areas are concentrated in the main urban areas, while the residential areas develop to suburban counties. This unbalanced relationship leads to the "tidal" traffic especially serious during the morning and evening rush hour, which is one of the important factors of this topic. Jingtong Expressway is one of the typical tidal phenomena in Beijing. It is innovative and prospective to study the tidal lane construction and operation scheme. Tidal lane, as an important means to solve asymmetric traffic, has been widely used at home and abroad. However, there is no precedent for its application to urban expressway or expressway. In the course of studying the tidal lane of Jingtong Expressway, the traffic flow and driving speed during the late rush hour are investigated, and the section with tidal lane is analyzed by calculating the distribution coefficient of the traffic flow and the average form speed of the vehicle. At the same time, the mathematical model of variable lane allocation optimization is established, and the rationality of lane allocation is verified by mathematical method. Compared with the long and short sections of the tidal lane, the paper analyzes the important nodes, the construction scheme, the entrance and exit, the section scheme, the technical and economic indexes, and analyzes the risks and problems of the two schemes. The operation guarantee scheme is the extremely important content of the tidal lane project of Jingtong Expressway. In the daily management, we should adopt the standard process to manage the steps of preparing, starting and closing the tidal lane before starting, so that the whole process can run smoothly and efficiently. In the emergency management, the first is to establish the organization guarantee, to establish the coordination group and the implementation group, and then to formulate the solution for all kinds of possible emergencies, to ensure that both traffic accidents and other emergencies can be handled calmly and quickly. Through the discussion and research on the tidal lane of Jingtong Expressway, not only the problems of its own construction and operation are solved, but also the traffic flow and speed data in the investigation can be taken as the basic data as the decision basis. Furthermore, the principles of traffic organization and traffic rights in complex traffic areas, as well as emergency rescue and management, can also provide reference for other similar cities to set up tidal lanes.
