Traffic interruption rate calculation method and system

The invention discloses a traffic interruption rate calculation method and system, and relates to the technical field of intelligent high-speed traffic situation analysis, study and judgment, and the method comprises the steps: obtaining the traffic event information of a current road segment through real-time video query; the average speed and the average time occupancy of the current road section are obtained through real-time data acquisition of a plurality of vehicle detectors and real-time data statistics of an intermodulation station; comprehensively judging the interruption state of the current road section according to the obtained traffic event information, the average speed and the average time occupancy; the method comprises the following steps: acquiring interruption states of upstream and downstream road sections of a to-be-detected road section, judging whether the to-be-detected road section is a road section influenced by interruption based on the interruption states of the upstream and downst
