【摘要】：快速路作為城市道路網絡的重要組成部分,在銜接交通干道、緩解交通擁堵等方面發(fā)揮了重要作用。在大力發(fā)展公共交通的今天,為了提高公交分擔率,許多大型城市的快速路上都設置了公交線路。由于受城市用地的限制和乘客換乘的需求,部分公交站設置在了快速路出入口附近,影響了出入口車流的正常運行。本文以此為背景,主要針對以下幾個方面展開公交站設置對快速路出入口通行能力影響的研究。論文首先分析了快速路公交站的形式及組織特點,并進一步討論了快速路出入口車輛的交通特性和公交車輛運行特征。在此基礎上,選取北京市多個公交站點進行調查分析,采集到不同公交站點的�？烤�路數和不同公交線路的公交車輛平均發(fā)車間隔時間,得到了高峰小時公交車到達頻率；選取北京市三環(huán)路進行相關數據采集,以視頻錄像的方式采集到交通總量、車輛構成、車輛路徑等詳細數據,并對主、輔路不同車型的速度分布進行擬合。其次,論文討論了公交站臺設置在快速路出入口的上下游時,公交車輛進站、停靠、出站三個階段對出入口附近社會車輛造成的干擾,進而分析對出入口通行能力的影響,并對這四種情況的受干擾程度和范圍進行比較分析,為公交站臺的設置提供相關建議。最后,介紹并分析了快速路出入口匝道連接處的三種通行能力模型。在此基礎上,建立了基于動力學理論并受公交站設置影響的出入口匝道連接處通行能力模型,并對模型參數α進行了說明。對公交站設置在快速路出入口匝道下游進行仿真分析,根據公交站位置和公交到達頻率的不同設計仿真實驗方案八類,共仿真15次,通過排隊長度、通行時間、延誤時間、通過車輛數評價指標分析公交站設置對出入口匝道通行能力的影響,并標定了模型參數α。
[Abstract]:As an important part of urban road network, expressway plays an important role in linking up traffic trunk roads and alleviating traffic congestion. In order to improve the sharing rate of public transport, bus lines have been set up on the express roads of many large cities in today's great efforts to develop public transport. Due to the restriction of urban land and the demand of passenger transfer, some bus stops are located near the entrance of express road, which affects the normal operation of traffic flow in and out of the entrance. Based on this background, this paper mainly focuses on the following aspects: the influence of bus station setting on the capacity of expressway entrance and exit. At first, the paper analyzes the form and organization characteristics of the expressway bus station, and further discusses the traffic characteristics and the running characteristics of the bus at the entrance and exit of the expressway. On this basis, we selected several bus stations in Beijing for investigation and analysis, collected the number of bus stops at different bus stations and the average departure interval time of bus vehicles with different bus lines, and obtained the bus arrival frequency in peak hours. The third Ring Road of Beijing is selected to collect the relevant data, and the detailed data such as traffic volume, vehicle composition, vehicle path and so on are collected by video recording, and the velocity distribution of different models of main and auxiliary roads is fitted. Secondly, the paper discusses the interference caused by the bus station set up in the upper and lower reaches of the expressway entrance to the social vehicles near the entrance, and then analyzes the influence on the access capacity of the entrance and exit, and the influence of the three stages of bus stop, stop and exit on the social vehicles in the vicinity of the entrance and exit is discussed in this paper. The interference degree and range of these four situations are compared and analyzed, and some suggestions are provided for the setting of bus station. Finally, three kinds of capacity models at the ramp junction of the expressway are introduced and analyzed. On this basis, the capacity model of on-ramp junction is established based on dynamic theory and influenced by the setting of bus station, and the parameter 偽 of the model is explained. According to the different bus station location and bus arrival frequency, eight simulation schemes are designed and simulated for 15 times. Through queue length, traffic time and delay time, the bus station is set up at the lower reaches of the ramp of the expressway, and according to the location of the bus station and the frequency of arrival of the bus, eight simulation schemes are designed and simulated for 15 times. Based on the evaluation index of vehicle number, the influence of bus station setting on the capacity of on-ramp is analyzed, and the model parameter 偽 is calibrated.
