【摘要】：随着我国城镇化进程的不断加快，中小城市各项建设也进入了高速发展阶段，城市交通建设优劣直接影响着中小城市形象与发展进程然而，中小城市的快速发展导致新的交通需求不断激增早晚高峰期交通压力不断加大，加之原有城区路网道路通行能力严重不足，使得城市道路交通拥堵问题日渐突出，成为制约中小城市健康发展进程的瓶颈和继续解决的难题交通信号控制作为缓解城市交通拥堵问题的重要手段，建成高效安全的交通信号控制系统在均衡路网交通流分布降低停车延误减少停车次数和尾气排放等方面起着至关重要的作用论文以公安部重点研究计划项目基于物联网技术的警务联动交通信号指挥系统为依托，以城市交通管理集成与优化技术公安部重点实验室为科研平台支持，旨在形成城市区域的交通信号优化控制方法，通过安装于交叉口的地磁检测器，实时采集交叉口交通信息参数，利用排队重置控制技术，构建基于排队重置方法的交通信号控制算法模型，建立区域道路交通信号优化配时方案，动态维持区域路段的空间占有率平衡，有效缓解了中小城市早晚高峰交叉口交通拥堵问题论文利用基于排队重置方法的交通信号控制研究成果，以浙江省奉化市为例，进行了奉化市的交通仿真评价和实战应用，一定程度上缓解了奉化市关键交叉口的排队溢出问题和交通拥堵问题，，取得了良好的社会效益和经济效益
[Abstract]:With the acceleration of urbanization in our country, the construction of small and medium-sized cities has entered the stage of rapid development. The advantages and disadvantages of urban traffic construction directly affect the image and development process of small and medium-sized cities. The rapid development of small and medium-sized cities leads to a continuous surge of new traffic demand in the morning and evening rush hour traffic pressure is increasing, coupled with the existing urban road network capacity is seriously inadequate, making urban road traffic congestion problem increasingly prominent. As an important means to alleviate the problem of urban traffic congestion, traffic signal control has become the bottleneck of restricting the healthy development of small and medium-sized cities and continued to solve the difficult problem. The establishment of an efficient and safe traffic signal control system plays an important role in balancing the traffic flow distribution of the road network, reducing the stopping delay and reducing the number of stops and exhaust emissions, etc. The thesis is based on the police traffic signal command system based on the Internet of things technology and the key laboratory of the Ministry of Public Security, which is the key laboratory of the Ministry of Public Security. In order to form the optimal control method of traffic signal in urban area, traffic information parameters of intersection are collected in real time by geomagnetic detector installed at intersection, and queue reset control technology is used. The traffic signal control algorithm model based on queue reset method is constructed, and the optimal timing scheme of regional traffic signal is established to maintain the spatial occupation balance of regional road sections dynamically. The problem of traffic congestion at morning and evening peak intersections in small and medium-sized cities has been effectively alleviated. Taking Fenghua City of Zhejiang Province as an example, the traffic simulation evaluation and actual combat application of Fenghua City are carried out by using the research results of traffic signal control based on queue reset method. To a certain extent, the problem of queue overflow and traffic congestion at key intersections in Fenghua City has been alleviated, and good social and economic benefits have been obtained.
