The invention relates to the field of intelligent transportation, in particular to a vehicle GPS track generation method and device based on historical track data characteristics and a storage medium. The method comprises the following steps: before a trajectory generation process, extracting trajectory point morphological features and basic features of a historical trajectory data set; selecting a starting point and an ending point meeting a preset rule in the historical trajectory data set, and generating a target path in combination with various driver preferences; simulating driving of the vehicle on a generated target path in track generation, randomly generating a sampling time interval, and obtaining an actual position of the vehicle at each sampling moment as a corresponding path point for generation; according to the morphological characteristics of the trajectory points, specifying the specific offset side of each target path point, generating the target switching rate of the target path, and reasonably exchanging the offset sides to realize the fitting of the target switching rate; and according to the final offset side of the target path point and the basic characteristics of the track point, realizing conversion from the path point to the corresponding track point, and efficiently generating the vehicle GPS track which accords with the real track form and contains the marking information.

    本发明涉及智能交通领域,尤其是指一种基于历史轨迹数据特征的车辆GPS轨迹生成方法、装置及存储介质。在轨迹生成过程前,提取历史轨迹数据集的轨迹点形态特征和基础特征;在历史轨迹数据集中选取满足预设规则的起点和终点,结合各类驾驶员偏好,生成目标路径;在轨迹生成中模拟车辆在生成的目标路径上行驶,随机生成采样时间间隔获取每个采样时刻车辆的实际位置作为对应路径点生成;根据轨迹点形态特征,指定各目标路径点具体偏移侧,生成目标路径的目标切换率,合理交换偏移侧,实现目标切换率的拟合;根据目标路径点最终偏移侧与轨迹点基础特征,实现从路径点到对应轨迹点的转换,高效生成符合真实轨迹形态的含标注信息的车辆GPS轨迹。
