- Аннотация: In this paper, toanalyze roadway work zone e®ects on vehicular °ow in a freeway ring, a macroscopic multi-lanetra±c model is proposed, the model describes the mandatory net lane-changing rate just upstream the roadway work zone with a random number model based on golden section analysis,and the net-changing rate in normal road segment with a lane-changing time model. Assumingthat the free °ow speeds on lanes I–III are 120, 100 and 90 km/h, respectively, with a numericalmethod of third-order accuracy, the model equations are solved numerically to simulate vehicular °ows in a three-lane freeway ring with a roadway work zone with a total length of 160 mand lane III completely banned. Numerical results show that the roadway work zone generatestra±c shock when initial density normalized by jam density is around 0.18.
