The invention discloses a travel flow prediction method and device, electronic equipment and a storage medium, relates to the technical field of artificial intelligence big data, and relates to intelligent traffic application. According to the specific implementation scheme, the method comprises the steps of 1, generating an implicit vector of each region according to the historical traffic characteristics of each region; and generating an implicit vector of each group according to the historical traffic characteristics of the plurality of groups, determining a target area and a target group related to the implicit vector according to the implicit vector of each area and the implicit vector of each group, and predicting the travel traffic of the target group in the target area according tothe implicit vector of the target area and the implicit vector of the target group. The method is based on the implicit vector of each region and the implicit vector of each group, the target area and the target group which are related to each other are determined, so that information sharing is performed among the related groups, accurate group flow prediction is realized, and the technical problem of relatively low travel flow prediction accuracy caused by incapability of accurately determining correlation among the groups in the prior art is solved.
Description
technical field [0001] This application relates to the technical field of artificial intelligence and big data, especially to the application of intelligent transportation, and in particular to a travel flow prediction method, device, electronic equipment and storage medium. Background technique [0002] When placing outdoor advertisements or providing travel services, it is often based on predicted travel traffic. For example, when delivering advertisements, it is possible to select the period of time when the target group travels the most intensively, so as to improve the delivery efficiency. Similarly, when providing travel services, if the travel flow and group composition information are known in advance, more flexible and personalized services can be provided. [0003] However, through the observation of travel behavior, it is found that different groups have different travel patterns at different times and in different regions. Based on historical observation data, ...
