【摘要】：随着我国经济的不断发展和高速公路的不断建设,高速公路交通事件的发生率也在不断增加,对人们的出行和生命安全造成极大的影响。如何对各路段分公司的交通事件处置能力进行评估、稽查和监管成为提高高速公路交通事件管理能力和运营服务水平亟需解决的问题。基于路网海量收费数据信息挖掘路网交通事件,是一种新的交通事件检测方式,这种方式可解决人工检测、车辆检测器检测所存在的诸多问题,并且无需配置新设备,可应用现有的路网数据,获得准确而全面的高速公路交通事件信息。本论文通过研究交通事件下的交通流特性,开展了基于车辆行程时间的交通事件判断方法,提出了利用路网间的相互关系确定交通事件发生区间的方法;进一步,依据车辆的入站时间、出站时间等相关交通参数,提出一种计算交通事件发生位置与发生时间的计算方法,并对该算法有效性进行分析,结果表明,该方法可以有效进行高速公路交通事件的判断。最后,本论文依托2014年陕西省路网收费数据,以Oracle数据库作为平台,通过Visual C++编程访问Oracle数据库,实现对路网交通事件的判断,并从宏观和微观层面对交通事件进行分析。本研究对今后交通服务、运行效率和交通管理等具有重要的现实意义。
[Abstract]:With the development of economy and the construction of freeway, the incidence of highway traffic accidents is increasing, which has a great impact on people's travel and life safety. How to evaluate the traffic incident handling ability of each branch company and how to check and supervise the traffic incident management ability and the operation service level of expressway become the urgent problems to be solved. Mining road network traffic events based on massive toll data of road network is a new traffic event detection method, which can solve many problems existing in manual detection and vehicle detection, and do not need to configure new equipment. The existing road network data can be used to obtain accurate and comprehensive highway traffic event information. By studying the characteristics of traffic flow under traffic events, this paper develops a method of judging traffic events based on vehicle travel time, and puts forward a method to determine the interval of traffic events by using the interrelation between road networks. Furthermore, according to the relevant traffic parameters, such as the inbound time and the exit time of the vehicle, a calculation method is proposed to calculate the location and time of the traffic event, and the effectiveness of the algorithm is analyzed. The results show that, This method can effectively judge highway traffic events. Finally, this paper relies on the 2014 Shaanxi Province road network toll data, takes the Oracle database as the platform, through the Visual C programming visits the Oracle database, realizes the judgment to the road network traffic event, and carries on the analysis from the macroscopic and the microscopic level to the traffic event. This study has important practical significance for traffic service, operation efficiency and traffic management in the future.
