摘要
随着我国机动车拥有量逐年攀升,交通事故的发生率也逐年升高,无信号灯公路交叉口由于没有信号灯指示及缺乏明确的路权分配,驾驶员往往无法准确判断出通过交叉口的安全行驶速度,导致无信号灯公路交叉口事故频发。研发的事故预警防撞系统通过微波雷达检测车辆信息,中央信息处理系统得出最佳通行方案,结合ZigBee无线通讯技术和语音播报技术将方案结果传递给驾驶员,达到驾驶员能够主动准确规避事故危险,保障车辆在无信号灯公路交叉口行驶的安全性。
With the increase of vehicle ownership in China year by year, the incidence of traffic accident is also increasing year by year. At a no-signaled highway intersection, a driver is often unable to accurately judge the safe driving speed through the intersection because of no signal light indication and lack of clear allowance of road right, which leads to the frequent accidents at no-signaled highway intersection. The developed accident pre-warming anti-collision system detects the vehicle information through the microwave radar, and the central information processing system obtains the optimal traffic scheme. Combined with ZigB ee wireless communication technology and voice broadcast technology, the scheme result is transmitted to the drivers. In this way, the drivers can actively and accurately avoid the danger of accidents in order to ensure the safety of vehicles driving at the no-signaled highway intersections.
