【摘要】：交通拥堵严重影响城市居民的出行舒适性，城市道路路网密度大、道路负荷度不尽相同，，利用动态的交通管理和组织手段，进行信号控制和交通诱导的动态协调控制，对道路路网均衡整合、提高出行舒适性具有重要的意义。运用先进的视频数据采集仪、超声波速度采集仪等设备对天津市区域路网固有属性及交通流参数进行实地调查，分析了区域路网交通拥堵的特点，确定了基本路段和交叉口影响范围划分的方法；以实际调研数据为基础，利用层次分析法分析得出交叉口延误、饱和度及路段行程速度是影响区域路网畅通可靠度的主要因素，从而建立了区域路网（单元）畅通可靠度评价体系，构建了区域路网畅通可靠度评价模型；运用区域路网路段饱和度和行程速度的实测数据，对BPR函数模型进行了标定，得到了区域路网基本路段阻抗函数模型；运用区域路网交叉口延误实地调查数据，对HCM延误模型进行了改进，提出了区域路网信号交叉口延误模型，进而构建了区域路网道路阻抗函数模型。通过对交通行为的调研与分析，基于交通流效用最大理论，设计了大胡同区域路网交通诱导方案，提出了基于驾驶员交通行为的区域路网动态协调控制策略，并用VISSIM仿真软件进行模拟验证，结果表明动态协调控制策略可降低14.9%的延误，缩短10.7%的行程时间。论文基于区域路网存在交通量不平衡、交通拥堵等现象，通过驾驶员的交通行为、路网交通流参数以及路网属性的分析，展开了动态协调控制的研究，不仅提高了区域路网通行效率，而且体现了以人为本的设计理念，对提高道路的安全性、舒适性具有重要的社会意义和现实意义。
[Abstract]:Traffic congestion seriously affects the travel comfort of urban residents. The density of urban road network is high and the road load degree is not the same. Dynamic traffic management and organization means are used to carry out dynamic coordination control of signal control and traffic guidance. It is of great significance for road network balance integration and improving travel comfort. By using advanced video data acquisition instrument, ultrasonic velocity collector and other equipment, the inherent attributes and traffic flow parameters of Tianjin regional road network are investigated on the spot, and the characteristics of traffic congestion in regional road network are analyzed. The method of dividing the influence range of the basic road sections and intersections is determined. Based on the actual investigation data, it is concluded by analytic hierarchy process that delay, saturation and travel speed are the main factors that affect the reliability of regional road network. The evaluation system of the unblocked reliability of the regional road network (unit) is established, and the evaluation model of the smooth reliability of the regional road network is constructed. Based on the measured data of saturation and travel speed of regional road network, the BPR function model is calibrated, and the impedance function model of basic section of regional road network is obtained. Based on the field investigation data of regional road network intersection delay, the HCM delay model is improved, and the delay model of regional road network signalized intersection is proposed, and then the road impedance function model of regional road network is constructed. Based on the investigation and analysis of traffic behavior, based on the theory of maximum utility of traffic flow, the traffic guidance scheme of the regional road network in hutong area is designed, and the dynamic coordinated control strategy of the regional road network based on the traffic behavior of drivers is put forward. The simulation results with VISSIM software show that the dynamic coordinated control strategy can reduce the delay by 14.9% and shorten the travel time by 10.7%. Based on the phenomena of traffic imbalance and traffic congestion in regional road network, the dynamic coordinated control is studied through the analysis of drivers' traffic behavior, traffic flow parameters and road network attributes. It not only improves the efficiency of the regional road network, but also embodies the people-oriented design concept. It has important social and practical significance to improve the road safety and comfort.
