【摘要】：当前中国城市交通的一个显著特征是机非交通流高度混合。由于国外的单纯机动车流与我国混合交通流差别很大,特别是在道路交叉口机动车、非机动车、行人相互干扰,致使道路通行能力严重下降,因此建立符合我国交通实际情况的交叉口机动车与非机动车微观仿真模型,不仅在理论上能够进一步促进交通流理论的完善和发展,而且在实践中还能够开发符合我国混合交通特征的交通仿真平台。本文采用元胞自动机模型将驾驶员行为选择引入演化规则,建立交叉口处机动车和非机动车混合交通流模型,不仅可以揭示机非混合交通在交叉口相互冲突的内在机理,还可以模拟机非混合交通下机动车和非机动车驾驶员的决策行为,具有重要的现实意义。论文首先阐述了研究背景。从机非冲突研究现状、驾驶员行为研究现状和混合交通流模型研究现状三个方面论述了目前国内外研究成果,在此基础上设计了论文的研究路线。然后,研究了交叉口处右转机动车和非机动车的交通特性,重点分析了右转机动车跟驰特性和穿越非机动车行为；非机动车在路段和交叉口运行特性,以及非机动车穿越机动车行为。最后,将交叉口离散化,划定元胞空间和元胞尺寸,制定机动车在路段、决策点和启动点处的行驶规则,以及非机动车行驶规则。基于以上规则建立机非混合模型,包括右转机动车穿越直行非机动车规则和直行非机动车穿越右转机动车规则。采用Matlab软件对机非混合模型编程和仿真。通过程序仿真数据得到了机动车和非机动车混行交通系统相图,模拟了右转机动车和直行非机动车的之间相互影响关系,验证了模型的准确性。同时分析了到达率、驾驶员行为选择概率和等待时间阈值等参数。
[Abstract]:At present, a prominent feature of urban traffic in China is the mixing of aircraft and non-traffic flow height. Because of the great difference between the pure motor vehicle flow abroad and the mixed traffic flow in our country, especially at the road intersection, motor vehicles, non-motor vehicles and pedestrians interfere with each other, resulting in a serious decline in the capacity of the road. Therefore, the establishment of a microscopic simulation model of intersection vehicle and non-motor vehicle in accordance with the actual traffic situation in China can not only further promote the improvement and development of traffic flow theory, but also promote the development of traffic flow theory. In practice, it is also possible to develop a traffic simulation platform that conforms to the characteristics of mixed traffic in China. In this paper, the choice of driver's behavior is introduced into the evolutionary rules by using cellular automata model, and the mixed traffic flow model of motor vehicle and non-motor vehicle at intersections is established, which can not only reveal the internal mechanism of the conflict between motor and non-mixed traffic at intersections. It can also simulate the decision-making behavior of motor vehicle and non-motor vehicle driver under non-mixed traffic, which has important practical significance. Firstly, the research background is expounded. This paper discusses the domestic and foreign research achievements from three aspects: the research status of non-conflict vehicle, driver behavior and mixed traffic flow model. Based on this, the research route of the thesis is designed. Then, the traffic characteristics of right-turn vehicle and non-motor vehicle at intersection are studied, and the characteristics of right-turn motor vehicle following and passing through non-motor vehicle are analyzed, and the running characteristics of non-motor vehicle in road section and intersection are analyzed. And the behavior of non-motor vehicles passing through motor vehicles. Finally, the intersection is discretized, the cellular space and cell size are delimited, and the driving rules of motor vehicles at road sections, decision points and starting points, as well as non-motor vehicle driving rules, are formulated. Based on the above rules, a non-hybrid model is established, which includes right-turn vehicle traversing non-motor vehicle rule and straight non-motor vehicle traversing right-turn motor vehicle rule. Matlab software is used to program and simulate the non-mixed model. The phase diagram of the mixed traffic system between motor vehicle and non-motor vehicle is obtained by the program simulation data. The interaction between right-turn vehicle and non-motor vehicle is simulated, and the accuracy of the model is verified. At the same time, the parameters such as arrival rate, driver behavior selection probability and waiting time threshold are analyzed.
