【摘要】：2014年重庆市实现地区生产总值14265.40亿元,同比增长10.9%,较全国高3.5个百分点。经济快速增长的同时,人们对公路出行也提出了新的期望和要求。以出行需求为中心的服务理念迅速兴起,开展出行信息服务的呼声越来越高,出行信息服务应运而生,出行信息服务已经日益成为一种现实的需求。普通公路交通信息是反映和评价整个公路网出行服务质量的重要信息。截止2014年,重庆市普通国省道上面布设有间歇式交通信息调查点1000个,比重式交通信息调查点282个,连续式交通信息调查点116个。然而,如何从海量的交通信息调查数据中挖掘有用数据,为普通公路出行者提供出行信息服务成为本文研究的重点。本文充分分析了重庆市普通公路交通信息调查点的现状和存在的问题;首次将密度比和行程车速指标运用到重庆市普通公路交通运行状态评价模型中,提出了不同交通运行状态下的密度比和行程车速分级判定阈值,在此基础上,分别提出了基于交通量和车头间距的2种不同的交通运行状态判定流程,检测精度分别达到了75%和90%;首次构建了宏观经济指标、中观旅游交通和货运交通指标、微观交通运行指标3个层次的普通公路交通出行服务质量评价指标体系;最后,提出了普通公路交通信息采集设备选取要求、布设原则和发布设备技术要求,并在高速公路出入口和旅游景区做了交通出行服务诱导工程示范应用。
[Abstract]:In 2014, Chongqing achieved a regional GDP of 1.42654 trillion yuan, an increase of 10.9 percent over the same period last year, 3.5 percentage points higher than that of the whole country.With the rapid economic growth, people also put forward new expectations and requirements for road travel.With the rapid rise of the service concept centered on travel demand, the voice of developing travel information service is becoming higher and higher, and the travel information service emerges as the times require, and the travel information service has become a kind of realistic demand day by day.General highway traffic information is an important information to reflect and evaluate the travel service quality of the whole highway network.As of 2014, there are 1000 intermittent traffic information survey points, 282 specific gravity traffic information survey points and 116 continuous traffic information survey points on the common provincial roads in Chongqing.However, how to mine the useful data from the massive traffic information survey data and provide the travel information service for the ordinary highway travelers becomes the focus of this paper.This paper fully analyzes the present situation and existing problems of general highway traffic information investigation points in Chongqing, and applies the density ratio and travel speed index to the evaluation model of Chongqing common highway traffic operation state for the first time.The decision threshold of density ratio and travel speed grade in different traffic operation state is put forward. On the basis of this, two different traffic operation state judging processes based on traffic volume and headway spacing are put forward respectively.The detection accuracy reached 75% and 90% respectively. For the first time, the evaluation index system of service quality of ordinary highway transportation was constructed, which included macroeconomic index, meso tourism traffic index and freight traffic index, micro traffic operation index, etc.The selection requirements of common highway traffic information collection equipment, the layout principle and the technical requirements of issuing equipment are put forward, and the demonstration application of traffic travel service guidance engineering in expressway entrance and exit and tourist scenic spot is made.
