STUDY OF AUTO-IDENTIFICATION ALGORITHM OF TRAFFIC CONGESTION ON URBAN EXPRESSWAYS BASED ON ANN

On the basis of traffic congestion pattern analysis and ANN information handling function, this paper develops an urban expressway traffic congestion identification algorithm based on ANN technology, and designs the special input variable for algorithm. Then algorithm is verified by actual measurement data of a certain urban traffic congestion state correctly, and is highly adaptive. At the same time marked algorithm can be directly applied to identify traffic congestion of difference expressway of the same city.
