The invention discloses an ETC door frame track data complementing method, which overcomes the problem of low timeliness and accuracy of highway vehicle inspection work caused by easy missing of ETC door frame data in the prior art, and comprises the following steps: obtaining a vehicle driving ETC track group, and identifying a missing track from the track group based on an isolation forest algorithm; for the missing track, key node information in the missing track data is extracted, and a key node track set is obtained; based on a shortest path search algorithm, traversing and filling the missing hub node information between adjacent nodes in the key node track set to obtain a hub node track set; and based on a road section toll station and gate information data table, searching and complementing missing portal data between two adjacent nodes in the hub node track set to obtain vehicle driving complete ETC track data. Complete driving track data of the expressway vehicles can be accurately and efficiently obtained, and the timeliness and accuracy of the expressway vehicle inspection work can be improved.
