Abstract

The invention discloses a traffic pattern recognition method, equipment and storage medium. Involves computer recognition technology. The traffic pattern recognition method includes: obtaining trajectory data and performing preprocessing to obtain the first trajectory data feature; performing outlier deletion on the first trajectory data feature to obtain the second trajectory data feature; performing journey segmentation on the second trajectory data feature , form the third trajectory data feature; input the third trajectory data feature into the traffic pattern recognition model training and output the traffic pattern recognition result. The present invention obtains the trajectory data, and preprocesses the trajectory data to obtain the first trajectory data feature, and deletes the outliers in the first trajectory data feature to obtain the second trajectory data feature, and then performs the second trajectory data feature The trip is segmented to form the third trajectory data feature, and the third trajectory data feature is input into the model for training, thereby improving the precision and accuracy of the model.

Description

technical field [0001] The invention relates to the technical field of computer identification, in particular to a traffic pattern identification method, device and storage medium. Background technique [0002] Pattern recognition is to divide the samples into certain categories according to the characteristics of the samples by means of calculation to study the automatic processing and interpretation of patterns, and the environment and objects are collectively referred to as "patterns". For example, traffic pattern recognition, which analyzes the user's mobile data to infer his travel mode, can improve many important problems faced by modern cities, such as traffic accidents, traffic congestion, and environmental pollution. [0003] The current traffic pattern recognition has the problem of low recognition accuracy and cannot provide users with better services. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems ...
