The invention relates to the technical field of intelligent traffic, and in particular, relates to a target road real-time traffic flow prediction method and device. The target road real-time traffic flow prediction method comprises the steps: acquiring traffic flow basic characteristics of a target road and real-time speed data of a floating car; according to the traffic flow basic characteristics of the target road, obtaining a traffic basic diagram of a road section similar to the target road, wherein the traffic basic diagram is suitable for establishing a relationship between traffic flow and driving speed of the road section; determining the real-time passing speed of the target road according to the real-time speed data of the floating car; and determining the real-time traffic flow of the target road according to the real-time passing speed based on the traffic basic diagram. According to the invention, the real-time traffic flow of the target road is detected, the real-time traffic operation condition is reflected, real-time reliable information is provided for travelers, and better path selection and path induction are facilitated, so that the travel time is shortened, and the traffic jam is reduced.
本发明涉及智能交通技术领域,具体涉及一种目标道路实时交通流量预测方法和装置。本发明所述目标道路实时交通流量预测方法包括:获取目标道路的交通流基本特征和浮动车实时速度数据;根据目标道路的交通流基本特征获取与目标道路同类路段的交通基本图,交通基本图适于建立路段的车流量与行车速度的关系;根据浮动车实时速度数据确定目标道路的实时通行速度;基于交通基本图,根据实时通行速度确定目标道路的实时交通流量。本发明实现了对目标道路实时交通流量的检测,对实时交通运行状况进行反映,给出行者提供实时可靠信息,便于更好地进行路径选择,实现路径诱导,以缩减出行时间,减少交通拥堵。
