【摘要】：当今社会,交叉口是交通事故的多发点,密切关系民生安全,因此交叉口问题一直是国内外交通学者重点研究的课题。无信号T型公路平面交叉口由于其相对宽松的路权管理更是各种交叉口问题的集中地。为了研究交叉口的行车安全和效率问题,本文从单个车辆的微观的角度,基于交叉口车辆的基本驾驶行为,以冲突为核心对无信号T型公路平面交叉口的支路与主路车流间的相互作用展开研究。本文所涉及车辆均为机动车辆。首先,本文综合分析了无信号平面交叉口车辆之间相互作用的内在机理和外在表现。分析的过程中总结了无信号交叉口存在的最为基本的微观驾驶行为,明确这些驾驶行为在车辆之间相互作用的过程中存在的意义；根据车辆之间不同形式的互相影响将车辆之间的相互作用形式分类,解释每一种作用方式的内在机理：对车辆穿越交叉口时受到的干扰以及产生的冲突做了详细的讨论。其次,本文基于实地采集的数据,选择以交叉口主路直行车辆和支路左转车辆作为主要研究对象,把冲突作为研究车辆之间相互作用的媒介,以车速、车头时距、穿越时间等为研究变量,从时间和空间两个方面去描述冲突对行车特征的影响性。本文用两个穿越点来描述支路左转车辆的空间行车特征。最后,本文通过构建冲突模型和行驶延误模型分别来描述车辆之间相互作用的内在关系及其影响强度。通过单因素影响分析以及双因素线性相关分析选择模型变量,并用SPSS进行拟合。通过模型,本文基于穿越点界定了支路左转车辆转弯轨迹的安全范围。
[Abstract]:In today's society, intersection is the point where traffic accidents occur, which is closely related to people's livelihood and security. Therefore, intersection problem has always been the focus of research by domestic and foreign traffic scholars. Unsignalized T-type highway intersections are the focus of various intersection problems because of their relatively loose road rights management. In order to study intersections, Traffic safety and efficiency issues, This paper is based on the basic driving behavior of intersections from the micro point of view of a single vehicle. Taking conflict as the core, the interaction between the branch road and the main road traffic flow at the unsignalized T-type road intersection is studied. The vehicles involved in this paper are all motor vehicles. In this paper, the internal mechanism and external performance of vehicle interaction at unsignalized intersections are comprehensively analyzed, and the most basic microscopic driving behaviors of unsignalized intersections are summarized in the process of analysis. To clarify the significance of these driving behaviors in the process of interaction between vehicles; to classify the forms of interaction between vehicles according to the different forms of interaction between vehicles, The internal mechanism of each mode of action is explained: the interference and the conflicts caused by the vehicle crossing the intersection are discussed in detail. Secondly, based on the data collected in the field, The main research object is the direct vehicle of the main road at the intersection and the left-turn vehicle of the branch road, the conflict is regarded as the medium to study the interaction between the vehicles, and the speed, the time of the vehicle front and the time of passing through are taken as the research variables. In this paper, two crossing points are used to describe the spatial driving characteristics of left-turn vehicles on branch roads. In this paper, the conflict model and the driving delay model are constructed to describe the internal relationship and the influence intensity of the vehicle interaction, and the model variables are selected by the single-factor analysis and the two-factor linear correlation analysis. The model is fitted with SPSS. Based on the crossing point, the safe range of the turning track of the left-turn vehicle on the slip road is defined in this paper.
