Summary:The invention discloses a car inspection device and toll data fusion based abnormal traffic state identification method and system. The method includes: firstly, collecting road data through a car inspection device and identifying abnormal state data of the car inspection device by adopting an ACI (automatic car identification) method; secondly, acquiring abnormal road toll state data through road toll data; finally, identifying the abnormal road toll state data by adopting an algorithm voting fusion method. With the method, the abnormal traffic state identification problem that a single data source algorithm is low in credibility and poor in actual application effect is solved, requirements of highway traffic flow on complexity and randomicity on time and space are met, multiple information sources are comprehensively utilized, the abnormal traffic state is identified form multiple aspects, and the abnormal traffic state is more accurately identified.
