The invention discloses a traffic jam analysis system based on urban public transportation network perception. The system comprises a first data acquisition module, a second data acquisition module, a data correction module, a vehicle-mounted information terminal, a data receiving module, a data analysis module, a jam pre-judgment module, a jam verification module and a map generation module, wherein the congestion verification module compares and verifies the current vehicle data according to the data of other vehicles; the congestion verification module is connected with the congestion sub-map generation module; the vehicle-mounted information terminal is located on a bus and is connected with the data receiving module through a 5G network, the data receiving module is connected with the data analysis module, and the data analysis module is used for classifying and analyzing data sent by the vehicle-mounted information terminal. According to the invention, a congestion verification module is added, so the data of side vehicles with deep time and related vehicles on the same road section can be verified, and the accuracy of congestion pre-judgment analysis is further improved.
