Based on the Traffic-Flow Wave Theory, a traffic flow wave model applicable to urban road incident congestion is proposed in this paper. The model is based on the discrete characteristics of urban congestion traffic flow and is derived from a Velocity-Density linear model. The queuing and dissipation of incident congestion is analyzed based on the new model - both on the existence of traffic controlling measures and on situations without traffic controlling measures - in which the influence from traffic controlling measures is described as interference wave. The results showed that the correct...
