A method for acquiring traffic data and a related device are applied to the technical field of traffic management, and in the embodiment of the invention, traffic time sequence data corresponding to a first position node and a second position node are acquired, and an entropy from the first position node to the second position node is calculated based on the traffic time sequence data of the first position node and the second position node; the entropy is used for indicating a directed edge weight from the first position node to the second position node; finally, the traffic data of the target geographic area are determined according to the directed edge weight from the first position node to the second position node, the directed edge weight can indicate the spatial association relation from the first position node to the second position node, and in the embodiment, the obtained traffic data are dynamic and have real-time performance, and the traffic data are more accurate. And the spatial association relationship from one position node to another position node can be reflected in a directed manner, so that accurate basic data can be provided for traffic management in a previous traffic environment with high complexity and real-time performance.
一种获取交通数据的方法及相关装置,应用于交通管理技术领域,本申请方法实施例中,获取第一位置节点和第二位置节点对应的交通时序数据,基于第一位置节点和第二位置节点的交通时序数据计算第一位置节点到第二位置节点的熵;熵用于指示第一位置节点到第二位置节点的有向边权;最后,根据第一位置节点到第二位置节点的有向边权确定目标地理区域的交通数据,该有向边权可以指示出第一位置节点到第二位置节点的空间关联关系,本实施例中,获取的交通数据是动态的,具有实时性的,且可以有向的反映出一个位置节点到另一个位置节点的空间关联关系,从而面对前高复杂性和实时性的交通环境,可以为交通管理提供准确的基础数据。
