【摘要】：近年来,中国汽车保有量急剧增加,交通出行量不断加大。由于交通拥堵导致交通事故频发、人员伤亡增加、经济损失严重和环境污染加剧等,严重影响我国的可持续发展。国内外专家学者不断探索交通拥堵问题的解决方法,大量研究表明:面对日益复杂的交通问题,仅依靠道路建设和传统交通管理方式,很难奏效。车路协同系统就是利用先进的信息与通讯技术,改善交通管理方式,提高路网的运输能力,能够有效的缓解交通拥堵、提高交通安全、降低交通事故率和减少环境污染等。路侧热点服务设备是保障智能交通系统发挥作用,有效进行路网管理和路网控制的基础环节,因此,如何布设路侧设备一直都是研究的热点。本文在充分分析国内外对路侧设备布设方案研究现状的基础上,首先,对常见的交通检测器进行对比分析,完成了路侧热点服务设备的选型;其次,根据路网中各类道路的特征,把路网分为高速路和城市路两类,针对两类路网的特性分别给出基于事件下行程时间估计的高速路路侧设备布设方案和基于图论和矩阵论的城市路布设方案;再次,基于路段流量建立路段相似性矩阵,考虑实际应用中布设成本和功效两方面问题,建立双目标的路侧设备布设优化模型,并采用宽容分层序列法对其求解;最后,调查路网中现有的交通信息采集设备,对主体捆绑的检测器进一步优化。文中结尾给出实例计算,采用微观交通仿真软件VISSIM进行仿真验证。结果表明:该优化模型对路网的交通流量的采集精度较高,能为路网管理的决策者决策提供有力保障。
[Abstract]:In recent years, the number of cars in China has increased sharply and the amount of transportation has been increasing. Traffic congestion leads to frequent traffic accidents, increased casualties, serious economic losses and aggravated environmental pollution, which seriously affect the sustainable development of our country. Experts and scholars at home and abroad continue to explore solutions to traffic congestion problem, a large number of studies show that: in the face of increasingly complex traffic problems, only rely on road construction and traditional traffic management, it is difficult to work. Vehicle-road cooperative system is to use advanced information and communication technology, improve traffic management, improve the transport capacity of road network, can effectively alleviate traffic congestion, improve traffic safety, reduce traffic accident rate and reduce environmental pollution, and so on. The road side hot spot service equipment is the basic link to ensure the function of the intelligent transportation system and effectively carry out the road network management and network control. Therefore, how to set up the road side equipment is always the hot spot of the research. In this paper, based on the analysis of the research status of road-side equipment layout at home and abroad, firstly, the common traffic detectors are compared and analyzed, and the selection of roadside hot-spot service equipment is completed. According to the characteristics of all kinds of roads in the road network, the road network is divided into two types: highway road and city road. According to the characteristics of the two types of road network, respectively, the highway side equipment layout scheme based on event travel time estimation and the urban road layout scheme based on graph theory and matrix theory are presented. Thirdly, the section similarity matrix is established based on the section flow. Considering the problem of cost and efficiency in practical application, the optimization model of road side equipment layout with double targets is established and solved by using the tolerant hierarchical sequence method. Finally, the existing traffic information collection equipment in the road network is investigated. The detector for the main bundle is further optimized. At the end of the paper, an example is given, and the microscopic traffic simulation software VISSIM is used to verify the simulation. The results show that the model has a high precision for traffic flow collection and can provide a strong guarantee for the decision making of road network management.
