【摘要】：利用车辆行驶过程中的卫星定位数据,可以计算和识别诸如超速和不按规定路线行驶等违规驾驶行为。准确有效的识别结果,能够为道路运输行业管理部门和运输企业实现动态安全管理提供充分可靠的管理依据。针对已有的违规驾驶行为辨识算法在抗数据噪声干扰方面的不足,提出了一种带抗噪声的违规驾驶行为辨识的方法。该方法结合预定行驶路线的地理坐标信息和分段限速值等基准判定数据,通过比较车辆当前行驶位置的卫星定位坐标与预定行驶路线最近坐标的球面距离值等,来判断和统计是否发生不按规定路线行驶的行为。通过比较车辆实时行驶速度、当前路段限速值和违规阈值等参数来判断和统计是否发生违规超速的行为。结合道路运输企业营运车辆实际运行过程中产生的大量车辆卫星定位数据,对所提出的辨识方法进行了试验验证。试验结果表明,与已有算法相比,本方法对于因漂移产生的卫星定位数据噪声有更强的抗干扰性,能够提高对不按规定路线行驶以及违规超速行为的识别准确率。
[Abstract]:Using the satellite positioning data in the course of vehicle driving, we can calculate and identify the illegal driving behaviors such as speeding and not following the prescribed route.Accurate and effective identification results can provide sufficient and reliable management basis for road transport industry management departments and transport enterprises to achieve dynamic safety management.In view of the shortcomings of the existing identification algorithms for illegal driving behavior in resisting the interference of data noise, a method for identification of illegal driving behavior with anti-noise is proposed in this paper.This method combines the geographic coordinate information of the predetermined driving route and the datum judgment data such as the segmented speed limit value, by comparing the spherical distance value of the satellite positioning coordinate of the current driving position of the vehicle with the nearest coordinate of the predetermined driving route, etc.To judge and count whether there is a failure to follow a prescribed route.By comparing the real time driving speed of vehicles, the speed limit and the threshold of violation, we can judge and calculate whether the overspeed behavior occurs or not.Combined with a large number of vehicle satellite positioning data generated during the actual operation of the vehicle in road transport enterprises, the proposed identification method is tested and verified.The experimental results show that compared with the existing algorithms, the proposed method has a stronger anti-jamming effect on the satellite positioning data noise caused by drift, and can improve the accuracy of identification of irregular route and overspeed behavior.
