【摘要】：在山地城市中，道路的平曲线和竖曲线都比平原城市复杂，主次干道结构不合理，路网中往往存在数量较多的畸形交叉口，许多适用于普通交叉口的渠化和控制方法不能直接运用到其中，处理不当则成为路网中交通事故和交通拥堵的多发点。本文的研究成果是在对山地城市交通特征深入研究的基础上，提出的一套针对山地城市中各类畸形交叉口的渠化和控制方法。本文提出的控制方法与渠化方法有机结合，对这些方法的适用条件也作了分析。本文首先从路网特征、交通流特征、居民出行特征和畸形交叉口特征四个方面细致地研究了山地城市的交通特征，根据山地城市中畸形交叉口相交道路的交叉角度、进口道数以及交叉口进口道的线形等因素，将山地城市畸形交叉口分为Y形交叉口、X形交叉口、H形交叉口、多路交叉口、错位交叉口和曲线进口道交叉口六类。为每一类畸形交叉口作了定义，分析了各类畸形交叉口需要重点解决的交通问题。从设置交通岛、车道功能划分、车道展宽设计、设置待行区域、设置路口导向线和左转交通流组织六个方面对平面交叉口渠化方法作了归纳总结。根据各类山地城市畸形交叉口的几何特征和交通问题，为每一类畸形交叉口提出了适宜的渠化方法和渠化重点。对平面交叉口控制方式及其选择进行了研究，分析了信号控制的分类、主要参数和评价指标。在此基础上，结合适用于各类山地城市畸形交叉口的渠化方法，论文提出了适用于各类山地城市畸形交叉口的控制方法，并对各类控制方法的适用条件作了分析。最后，，本文为每一类畸形交叉口选取典型案例，将论文提出的渠化和控制方法运用到对各畸形交叉口的改善中，利用交叉口配时优化软件synchro和微观交通仿真软件VISSIM建模仿真，对仿真结果进行以分析和比较，验证本文所提方法的适用性和有效性。
[Abstract]:In mountainous cities, the horizontal and vertical curves of roads are more complicated than those of plain cities, the structure of primary and secondary main roads is unreasonable, and there are often a large number of abnormal intersections in the road network. Many channelization and control methods suitable for common intersections can not be directly applied to them, and improper handling will become the frequent point of traffic accidents and traffic congestion in road network. Based on the in-depth study of the traffic characteristics of mountainous cities, this paper presents a set of methods for channelization and control of various deformed intersections in mountainous cities. The proposed control method is combined with the canalization method, and the applicable conditions of these methods are also analyzed. Firstly, this paper studies the traffic characteristics of mountainous cities from four aspects: road network characteristics, traffic flow characteristics, resident travel characteristics and abnormal intersection characteristics, according to the intersection angle of the abnormal intersections in mountainous cities. According to the factors such as the number of entrances and the alignment of intersections, the malformed intersections in mountainous cities are divided into six types: Y-shaped intersections, multi-path intersections, staggered intersections and curved entrance intersections. The definition of each kind of malformed intersection is given, and the traffic problems that need to be solved are analyzed. The methods of channelization at intersections are summarized from six aspects: setting up traffic island, dividing lane function, designing lane widening, setting up waiting area, setting up intersection guide line and traffic flow organization of left turn. According to the geometric characteristics and traffic problems of the deformed intersections in mountainous cities, this paper puts forward the appropriate channelization methods and key points for each kind of abnormal intersections. The control mode and selection of intersection are studied, and the classification, main parameters and evaluation indexes of signal control are analyzed. On this basis, combined with the canalization method suitable for all kinds of mountainous city malformed intersections, the paper puts forward the control methods suitable for all kinds of mountainous city malformed intersections, and analyzes the applicable conditions of all kinds of control methods. Finally, this paper selects typical cases for each kind of malformed intersection, applies the canal and control methods proposed in the paper to the improvement of each abnormal intersection, and uses the intersection timing optimization software synchro and the microscopic traffic simulation software VISSIM to model and simulate. The simulation results are analyzed and compared to verify the applicability and effectiveness of the proposed method.
