【摘要】：信號交叉口作為城市道路網(wǎng)絡(luò)的重要組成部分，在路網(wǎng)的銜接中起著至關(guān)重要的作用。在信號交叉口處，由左轉(zhuǎn)車流所產(chǎn)生的沖突、延誤和交通事故最多，這嚴(yán)重影響到了道路交通安全和運(yùn)行效率，左轉(zhuǎn)車流也成為信號交叉口交通管理與組織的重難點所在。研究信號交叉口左轉(zhuǎn)車流的通行能力，不僅可以作為交叉口規(guī)劃、設(shè)計和運(yùn)營管理的主要依據(jù)，也能夠進(jìn)一步促進(jìn)交通工程基礎(chǔ)理論的發(fā)展。 本文按照信號交叉口控制方式的不同，分別對保護(hù)型和許可型左轉(zhuǎn)相位條件下的左轉(zhuǎn)車流通行能力進(jìn)行了研究。首先，從信號交叉口通行能力、保護(hù)型左轉(zhuǎn)相位條件下的左轉(zhuǎn)車流通行能力和許可型左轉(zhuǎn)相位條件下的左轉(zhuǎn)車流通行能力三個方面，分別對目前國內(nèi)外的研究現(xiàn)狀進(jìn)行了具體介紹。通過對北京市13處不同左轉(zhuǎn)控制方式下的信號交叉口調(diào)查，采用實地觀測與統(tǒng)計分析相結(jié)合的方法，研究了信號交叉口左轉(zhuǎn)車流的交通特性和組織特性。對于保護(hù)型左轉(zhuǎn)相位條件下的左轉(zhuǎn)車流，首先通過對不同數(shù)量左轉(zhuǎn)車道的飽和車頭時距進(jìn)行統(tǒng)計分析，建立了左轉(zhuǎn)車道數(shù)和左轉(zhuǎn)車流車頭時距的關(guān)系模型，然后以我國的停車線法為基礎(chǔ)，，針對單條或多條左轉(zhuǎn)專用道、設(shè)有左轉(zhuǎn)待行區(qū)的左轉(zhuǎn)車道和允許車輛掉頭的左轉(zhuǎn)車道三種情況，分別對其通行能力進(jìn)行了研究。而對于許可型左轉(zhuǎn)相位條件下的左轉(zhuǎn)車流，探討其通過交叉口的三種可能方式，應(yīng)用間隙接受理論的相關(guān)知識，重點研究了左轉(zhuǎn)車流利用對向直行車的可接受間隙通過信號交叉口的通行能力。在觀測大量接受間隙和拒絕間隙的基礎(chǔ)上，應(yīng)用Raff法和Ashworth法標(biāo)定左轉(zhuǎn)車流臨界間隙值為3.9s，并建立相應(yīng)的通行能力模型，從而進(jìn)一步得到了左轉(zhuǎn)車流總的通行能力模型。此外，在每個通行能力模型的最后還分別引入了典型算例，通過算例對模型的具體使用方法進(jìn)行了說明。
[Abstract]:As an important part of urban road network, signalized intersection plays an important role in road network connection. At the signalized intersection, the conflicts, delays and traffic accidents caused by the left-turn traffic flow are the most, which seriously affect the traffic safety and operation efficiency, and the left-turn traffic flow has become the most difficult point in traffic management and organization of signalized intersections. The study of traffic capacity of left-turn traffic at signalized intersections can not only serve as the main basis for planning, design and operation management of intersections, but also further promote the development of basic theory of traffic engineering. According to the different control modes of signalized intersection, this paper studies the traffic capacity of left-turn traffic under the condition of protected and permitted left-turn phase respectively. First of all, from three aspects: the capacity of signalized intersection, the capacity of left turn traffic under the condition of protection left turn phase and the left turn flow capacity of permitted type left turn phase, The current research situation at home and abroad is introduced in detail. In this paper, the traffic and organization characteristics of left-turn traffic flow at 13 signalized intersections in Beijing are studied by combining field observation with statistical analysis. For the left turn flow under the condition of the protective left turn phase, the relationship model between the number of left turn lanes and the left turn flow head time distance is established by the statistical analysis of the saturated headway time distance of different number of left turn lanes. Then, based on the parking line method of our country, the capacity of single or multiple left turn lanes, left turn lane with left turn waiting area and left turn lane allowing vehicle to turn around are studied respectively. For the left turn flow under the permitted left turn phase condition, three possible ways of passing through the intersection are discussed, and the relevant knowledge of the theory is accepted by using the gap. The capacity of left-turn traffic to pass through signalized intersections by using the acceptable gap of the opposite direct vehicle is studied emphatically. On the basis of observing a large number of acceptance clearance and rejection gap, the critical clearance of left turn flow is calibrated by Raff method and Ashworth method, and the corresponding capacity model is established, thus the total traffic capacity model of left turn flow is further obtained. In addition, a typical example is introduced at the end of each capacity model, and the concrete application method of the model is illustrated by an example.
