【摘要】：自改革开放以来,我国高速公路从零记录跃升为如今的世界第一,但是与此同时,我国高速公路的管理体系却相对建设速度滞后不少。数据表明我国每年交通事故的数量和严重性都在不同程度地爬升。而且,大多事故的严重程度往往并非首次事故造成的,而是首次事故发生后,又引发了连环的二次事故。这种连锁机制会导致事故陷入不可控的地步,从而造成更加严重的后果。因此大家也越来越关注这一严峻的形势。如何充分发挥高速公路廉价、高效的优点是我国高速公路管理部门面临的关键问题。由此可见,针对高速公路,在首次交通事故发生后能够实时或及时发送警告信息给相关主体,就能够避免二次事故发生,从而阻止事故进一步升级。本文主要是为了实现高速公路二次事故预警以避免交通事故升级而设计的一套预警系统,论文设计了复合地图匹配算法并应用与系统的程序设计中。在对地图匹配算法和高速公路二次追尾事故特点及诱因的研究基础上,针对我国高速公路自身特点而设计的一套综合预警系统。该系统结合了移动互联网技术,对事故地点进行准确定位,能够实时、高效地预警撞车事故发生点。本系统是在智能终端技术的基础上建立的预警系统,系统主要有终端数据采集模块、云端预警决策模块和预警信息通知模块等组成。交通安全领域的研究在我国取得了一些发展,但是在技术实现领域还是不足、实际运营成果也是捉襟见肘的。由此可见,将成熟的智能终端技术应用于高速公路交通安全预警系统中是我国智能交通工作(ITS)发展的一个趋势。
[Abstract]:Since the reform and opening up, the expressway of our country has leapt from zero record to the first in the world now, but at the same time, the management system of expressway in our country has lagged behind the speed of construction. The data show that the number and severity of traffic accidents in China are climbing in varying degrees every year. Moreover, the severity of most accidents is often not caused by the first accident, but after the first accident, it leads to a series of secondary accidents. This chain mechanism can lead to uncontrollable accidents, with more serious consequences. As a result, people are increasingly concerned about this grim situation. How to give full play to the advantages of cheap and efficient freeway is the key problem faced by expressway management department in China. From this, it can be seen that after the first traffic accident, the warning information can be sent to the relevant subject in real time or in time, so that the secondary accident can be avoided and the further escalation of the accident can be prevented. In this paper, a set of early warning system is designed to realize the expressway secondary accident warning to avoid the traffic accident escalation. The paper designs the matching algorithm of composite map and the application of the system in the program design. Based on the study of map matching algorithm and the characteristics and inducement of secondary rear-end accidents of freeway, a set of comprehensive early-warning system is designed according to the characteristics of freeway in China. The system combines the mobile Internet technology to locate the accident site accurately and can warn the accident spot in real time and efficiently. The system is an early warning system based on intelligent terminal technology. The system consists of terminal data acquisition module, cloud early warning decision module and early warning information notification module. The research in the field of traffic safety has made some progress in our country, but in the field of technical realization is still insufficient, the actual operational results are also limited. It can be seen that the application of mature intelligent terminal technology in expressway traffic safety early warning system is a trend of (ITS) development in China.
