The effect of moving bottlenecks on a two-lane traffic flow

摘要: In this paper, we study the effect of moving bottlenecks on traffic flow. The full velocity difference (FVD) model is extended to flow a two-lane highway, and new lane changing rule proposed reproduce vehicular behavior. Using model, derive fundamental current—density diagrams for with bottleneck. Moreover, typical time—space diagram highway shows formation dissipation Results demonstrate that bottleneck enlarges increase density, but can be reduced by increasing maximum heavy truck. effects multiple under different conditions are investigated. becomes more remarkable when coupling occurs.
