【摘要】：交通路网作为社会发展的一个主要服务载体，其稳定性是与国家经济发展直接相关的。城市在不断发展，道路交通的拥堵问题日益严重，逐步从单一的路段或者交叉口拥挤问题演化为片区道路的拥堵。为了将这一问题解决，本论文从以下几个方面对城市道路交通状况进行分析研究。首先，，本文针对国内外交通状态的研究状况进行概述，对于中外学者及专家对城市道路交通运行状态评价方法的研究，进行进一步的总结归纳。根据以往研究内容能够看出，要分析道路的交通状态情况，单纯依据单点交叉口或路段的交通状况来评价片区甚至整个路网的交通状况是不全面的，因此，需要对某个片区，甚至片区路网整体的交通状态进行评价分析。其次，阐述了专家学者针对交叉口延误及车辆排队的几种常见模型，以乌鲁木齐市友好北路与新医路交叉口为例，借助VISSIM微观仿真软件与数学延误模型，将仿真结果中的排队长度、延误和行程时间等数据，与Webster延误模型计算结果进行比对，进而确定交叉口延误值，对交叉口的交通运行状态进行分析。最后，分别以乌鲁木齐市高新区、克拉玛依市老城区为例，对片区道路交通状况进行分析，提出以片区交叉口进口饱和度、路段平均行车速度作为交通状态评价指标，以一种新的基于交通状态系数的道路交通运行状态评价方法，借助VISSIM仿真模型输出的相关评价数据，探讨分析该评价方法是否适用于对片区道路交通运行状态的评价。
[Abstract]:Traffic network as a main service carrier of social development, its stability is directly related to the national economic development. In order to solve this problem, the traffic situation of urban roads is analyzed and studied from the following aspects. First of all, this paper summarizes the research situation of traffic status at home and abroad, and studies the evaluation methods of urban road traffic operation state by Chinese and foreign scholars and experts. According to the previous research content, we should analyze the traffic condition of the road. It is not comprehensive to evaluate the traffic condition of the whole road network or even the whole area based on the traffic condition of the single point intersection or the section of road. Therefore, it is necessary to evaluate the traffic condition of a certain area. Even the whole traffic state of the whole area road network is evaluated and analyzed. Secondly, this paper expounds several common models of intersection delay and vehicle queue, taking the intersection of friendly North Road and Xinyi Road in Urumqi as an example. With the help of VISSIM simulation software and mathematical delay model, the data of queue length, delay and travel time in the simulation results are compared with the calculated results of Webster delay model. Then the delay value of intersection is determined, and the traffic state of intersection is analyzed. Finally, taking Urumqi High-tech Zone and Karamay City as an example, the paper analyzes the road traffic situation of the district, and puts forward the saturation of the intersection entrance. As an index of traffic state evaluation, a new evaluation method based on traffic state coefficient is used to evaluate the road traffic running state, and the relevant evaluation data are outputted by VISSIM simulation model. This paper discusses whether the evaluation method is applicable to the evaluation of the road traffic running state in the area.
