为了解决现有的地图匹配方法在快速路出入口区域由于车辆轨迹与地图路径相差较大而导致匹配较易出错的问题,提出了一种地图匹配中快速路出入口车辆行为模式识别方法。该方法通过分析车辆在快速路出入口的行驶特点,对可能的行驶行为建立行为模式,并根据车辆行为特征对行为模式进行识别,最后通过试验对该方法在出入口地图匹配中的效果进行了验证。结果表明:将该方法应用于地图匹配中,可以根据行为模式识别结果确定车辆所在道路,从而实现快速路出入口的准确匹配。
In order to solve the problem that the existing map matching method is more error-prone in the entrance / exit area of the expressway due to the large difference between the vehicle path and the map path, a method for vehicle behavior pattern recognition at the entrance / exit of expressway in map matching is proposed. By analyzing the driving characteristics of the vehicles at the entrances and exits of expressways, this method establishes a behavioral model for possible driving behavior and identifies the behavioral patterns according to the vehicle behavioral characteristics. Finally, the effect of this method on the map matching at entrances and exits is verified through experiments. The results show that this method can be applied to map matching to determine the road where the vehicle is located according to the results of behavior pattern recognition so as to achieve accurate matching of expressway entrances and exits.
