The invention belongs to the technical field of traffic engineering, and particularly relates to a traffic speed prediction method based on multi-moment traffic flow. The method predicts the vehicle speed of a to-be-measured position at the current moment and before and after moments according to the vehicle flow and vehicle speed of the modeling position at the current moment and before and after moments and the vehicle flow of the to-be-measured position at the current moment and before and after moments. The method comprises the steps of data acquisition, matrix construction, training and speed prediction. The invention relates to a short-time traffic speed prediction method based on flow information, which can solve the technical problems that the cost is too high as hardware equipment needs to be additionally arranged on road facilities for speed monitoring, and the speed detection precision is low as target shielding exists in speed measurement equipment. According to the method, expensive traffic speed measuring instruments such as a laser radar do not need to be arranged on a road, the future traffic speed and the like can be pre-judged only according to the traffic data flow, and the detection cost is low.

    本发明属于交通工程技术领域,特别涉及一种基于多时刻交通流量的交通速度预测方法。所述方法根据建模位置在当前时刻及其前后时刻的车流量和车速,以及待测位置当前时刻及其前后时刻的车流量,预测出待测位置在当前时刻及其前后时刻的车速。该方法包括:数据采集、矩阵构造、训练、速度预测几个步骤。本发明是基于流量信息的短时交通速度预测方法,可以解决道路设施需要加装硬件设备进行速度监测导致的成本过高,且测速设备存在目标遮挡导致检测的速度精度低下的技术问题;本发明无需在道路上设置激光雷达等较为昂贵的交通测速仪器,仅凭交通数据流量即可预判未来的交通速度等,检测成本低廉。
