The invention provides a road operation condition judgment method and device, a storage medium and a program product. The method comprises the steps of obtaining a track data set of multiple vehicles of a target road section; traversing the trajectory data set to obtain the driving speed of the target road section; and determining the operation condition of the target road section based on the lane number, the traffic flow and the free flow speed of the target road section in unit time, and the in-transit quantity and the driving speed of the last time period. According to the method, a plurality of basic traffic indexes such as traffic flow, in-transit quantity, average speed and free flow speed are combined, judgment logic of the road operation condition is established, the introduced traffic index types are more comprehensive, the road operation condition is judged and analyzed from a lane level and a road level by adopting different calculation logics in different application scenes, and the road operation condition is more accurate. Accuracy of actual engineering deployment and analysis results is improved, and data support is provided for subsequent congestion prediction.
本发明提供一种道路运行状况判断方法、设备、存储介质及程序产品,方法包括:获取目标路段的多辆车的轨迹数据集;遍历轨迹数据集,得到目标路段的行驶速度;基于单位时间内目标路段的车道数、交通流量、自由流速度、最后时段的在途量以及行驶速度,确定目标路段的运行状况。本发明结合了交通流量、在途量、平均速度、自由流速度等多项基础交通指标,建立了道路运行状况的判断逻辑,引入的交通指标类型更为全面,并且在不同的应用场景下,采用了不同的计算逻辑对道路运行状况从车道级、道路级进行判断分析,提高了实际工程化部署以及分析结果的准确性,为后续的拥堵预测提供了数据支撑。
