摘要
高速公路是当前道路交通的主要形式之一,根据目前交规要求,事故发生后应在事故前150 m摆放警示标志,并打开双闪预警。但由于高速公路车速快,加之路况、天气等因素,往往因警示装置不明显造成次生事故,并引发重大交通事故。本文探讨了一种由固定式简易预警装置和配套中心端控制平台组成的半反馈式高速公路预警系统,在事故报警后中心平台远程控制前端预警系统开启,由于装置明显并将预警距离拉长,有效降低了次生事故的发生,提高了道路交通安全水平。
Highway is one of the main forms for the current road traffic. According to the current traffic rules,when the accident happened,warning signs should be put 150 m before the accident site and double flash should be opened for warning. But as a result that the vehicle speed is fast on highway,and together with the factors of road conditions,weather and so on,the secondary accidents often happen for the unobvious warning device,so to cause serious traffic accident. This paper discusses a kind of half-feedback type highway warning system composed by the stationary simple early warning device and supporting center platform. After the accident alarming,the front-end warning system of remote control in center platform is opened. Because the device is obvious and stretches the warning distance,the happening of secondary accidents is effectively reduced,and the level of road traffic safety is improved.
