WebbFigure 13. The left column plots show the empirical data of flow (top) and lane usage fraction (bottom) as function of density (Wiedemann 1995). The density, flow, velocity and lane usage fraction are measured in units of veh/km/2lanes, veh/h/2lanes, km h−1 and %, all averaged over 1 min intervals. The right column plots show the simulation result … Webb30 sep. 2010 · Abstract. The physics of traffic congestion occurring at a moving bottleneck on a multi-lane road is revealed based on the numerical analyses of vehicular traffic with a discrete stochastic traffic flow model in the framework of three-phase traffic theory. We find that there is a critical speed of a moving bottleneck at which traffic …
