摘要：
For timely finding and dynamic warning of traffic congestion state in urban road network, the dynamic tracking of traffic congestion in urban road network was analyzed. And the problem of traffic congestion in urban road network was studied with multi-dimension connection number. Based on the comprehensive analysis of relevant attributes, changing regulation, space distribution and discrimination method of traffic congestion, the authors analyzed formation mechanism of traffic congestion in urban road network. Based on the analysis of traffic congestion characteristics and influence factors, a monitoring index system of traffic congestion in urban road network was presented. Based on the determination of the assessment levels, the monitoring model of urban traffic congestion was designed with multi-dimension connection number. The validity of the model was checked at the end. The results have revealed the validity and maneuverability of the study, and thus a theory foundation for developing the decision support system for urban traffic congestion management is provided.
