The embodiment of the invention discloses a traffic data processing method, device and equipment based on heterogeneous truck flow, and relates to the technical field of data processing. The method comprises the following steps: determining a plurality of traffic flow characteristics according to different truck types, and taking the traffic flow characteristics as traffic state evaluation indexes; setting a classic domain and a node domain according to a preset traffic state grade and a traffic state evaluation index; determining a traffic state level matter element and a correlation function of the to-be-evaluated state road section according to the classic domain and the node domain; constructing a judgment matrix; determining an entropy weight coefficient according to the judgment matrix; performing weighted summation according to the correlation function, the traffic state level matter elements and all entropy weight coefficients to obtain a comprehensive correlation degree; and determining the maximum comprehensive association degree in all the comprehensive association degrees as a target comprehensive association degree, thereby determining the target traffic state grade of the to-be-evaluated state road section. In this way, the complexity of the traffic state can be comprehensively reflected by selecting a plurality of truck flow characteristic indexes for evaluation.
本发明实施例公开了一种基于异构货车流量的交通数据处理方法、装置及设备,涉及数据处理技术领域。该方法包括:根据不同货车车型确定多个交通流量特征,将交通流量特征作为交通状态评估指标;并根据预设交通状态等级和交通状态评估指标设置经典域和节域;根据经典域和节域,确定待评估状态路段的交通状态等级物元和关联函数;构建判断矩阵;根据判断矩阵确定熵权系数;根据关联函数、交通状态等级物元和所有熵权系数进行加权求和,得到综合关联程度;将所有综合关联程度中的最大综合关联程度确定为目标综合关联程度,从而确定待评估状态路段的目标交通状态等级。这样,通过选用了多个货车流量特征指标进行评估,可全面反映交通状态的复杂性。
