摘要
车道级违法行为指移动目标相对于地面车道或其他移动目标而言,相对位置移动在一个车道级别内的、违反交通法规的行为。由于数据精度等问题,该类行为一直是交管执法取证中的难点。高精度北斗/GPS定位的实现依靠广域实时精密定位技术,通过全球/全国建立的北斗地基增强网系统,将卫星定位精度从平均4~20 m左右提升到大众应用亚米级的水平。从高精度定位技术入手,设计了具有车道级定位能力的执法取证终端,并在无锡等地开展了技术验证。实验表明,这些技术可为车辆行为分析、车辆主动安全等车联网系统提供支撑。
Lane level traffic violation refers to the behavior of the moving target violates the traffic laws whose relative position moves within one lane level relative to the ground lane or other moving targets. Due to the inadequate data accuracy, this kind of behavior has always been a difficulty for traffic management law enforcement and evidence collection. The realization of high precision BDS/GPS positioning relies on wide area real-time precision positioning technology. The satellite positioning accuracy has improved from an average of about 4-20 meters to a public level of submeter through the national/global BDS ground-based augmentation system. From the point of view of high precision positioning technology, we have designed a terminal with lane level positioning ability for law enforcement and evidence collection in this paper, and we have carried out technical validation in Wuxi and other places. The experiments showed that these technologies could provide support for the IOV system such as vehicle behavior analysis and vehicle active safety.
