The invention discloses a trajectory generation method fusing time-space correlation information, and belongs to the technical field of intelligent traffic control, and the vehicle trajectory generation method comprises the steps: inputting a collected historical trajectory sequence of a current vehicle in a current driving state and a current road network topology into a trained trajectory prediction model, a geographic topology module in the trajectory prediction model determines a first prediction probability of each prediction result based on spatial relationship information corresponding to the current road network topology, and a time sequence association module determines a second prediction probability corresponding to each prediction result based on time sequence association information in a historical trajectory sequence; fusing the first prediction probability and the second prediction probability by using a space-time fusion module to obtain an accumulated confidence probability of each line measurement result; and finally, a discriminator selects a target driving track according to the accumulated confidence probability. According to the method, the historical trajectory sequence and the current road network topology in the current driving state are considered, and the vehicle prediction trajectory can be more accurately generated.

    本发明公开了一种融合时空关联信息的轨迹生成方法,属于智能交通控制技术领域,所述车辆轨迹生成方法包括:将采集的当前车辆当前行驶状态下的历史轨迹序列和当前路网拓扑输入训练好的轨迹预测模型中,轨迹预测模型中的地理拓扑模块基于当前路网拓扑对应的空间关系信息确定每种预测结果的第一预测概率,时序关联模块基于历史轨迹序列中的时序关联信息确定每种预测结果对应的第二预测概率,再利用时空融合模块将第一预测概率和第二预测概率进行融合得到每种行测结果的累计置信概率;最后判别器根据累计置信概率选出目标行驶轨迹。该方式考虑了当前行驶状态下的历史轨迹序列和当前路网拓扑,可以获得更加准确地生成车辆预测轨迹。
