Fusion and Recognition Model of Traffic State on High-Grade Highway Segment
Zhao Yu-qiao · Journal of Chongqing Jiaotong University · 2010
In order to provide reasonable and accurate traffic status information for the traffic managers,a novel method for traffic state recognition based on vague set theory is proposed.According to the characteristics of discreteness,fuzziness and time-variant in the detecting units,decision-making information of adjacent detections units at the same level is merged to obtain a sequence of traffic state blocks.A weighted distance formula is proposed to turn the position and length of traffic state block into weights,and based on which,the fusion and recognition model of traffic states information on high-grade highway segment is established.Examples verify the effectiveness of the model,which also provide a new way to recognize the traffic state information of high-grade highway segment.
