Congestion identification algorithm research and realization for networking intelligent traffic

According to RFID detection system characteristic,a new traffic congestion judging algorithm based on networking front information collecting technology is proposed for urban freeway normal traffic congestion.The paper describes the traffic congestion judging criterion by carrying out contrast analysis and statistical derivations for the city road intersection collected traffic flow,vehicle relative increment of time share and place average speed.Then it demonstrates the traffic flow characteristics when the traffic congestion arises from the viewpoint of theory.The corresponding congestion detection index and classification algorithm is also constructed in this paper.Finally correctness of the algorithm is verified by the use of Matlab programming combined with the actual traffic measurement data.
