The invention provides a road condition prediction method and device and a storage medium. According to the method, future road conditions are predicted based on heterogeneous graphs; according to theroad identification, the road link relationship and the link relationship type of each road in a target area, a heterogeneous road map of the target area is acquired; various types of link relationsbetween roads are considered, so that the constructed heterogeneous road map matches the actual situation; moreover, a space-time diagram of the heterogeneous road map is formed; training is carried out on the space-time diagram to predict the road condition of each road in the next time period, so that the predicted road condition information conforms to the actual situation, the accuracy of roadcondition prediction is improved, a decision-making basis for governing congestion can be provided for urban traffic managers, and route planning, navigation and the like are provided for travel of people.

    本申请提供一种路况预测方法、装置及存储介质,该方法基于异质图预测未来路况,其中,根据目标区域的各个道路的道路标识、道路链接关系和链接关系类型,获得目标区域的异质道路图,考虑了道路之间多种类型的链接关系,使得构建的异质道路图与实际情况相匹配,而且,本申请实施例形成异质道路图的时空图,在该时空图上,进行训练预测每个道路下一个时间段的路况,使得预测的路况信息与实际情况相符,提升了路况预测的准确率,进而,能够为城市交通管理者提供治理拥堵的决策依据,为人们出行提供线路规划及导航等。
