| 摘 要： | 基于元胞自动机NaSch交通流模型,提出弯道交通流的能耗公式.在开放边界条件下研究不同弯道曲率半径、弧长、摩擦系数等因素对各种能耗的影响.模拟结果表明:在不同影响因素情况下,对应的各种能耗随进车概率的变化趋势相似,安全能耗总是最小的,趋于零;弯道的曲率半径和摩擦系数越小、弯道弧长越长,出现能耗平台的临界进车概率点越小,...

| Abstract: | Based on cellular antomotion NaSch model,the energy loss of traffic flow in the bend was investigated in this paper.The formula of energy loss was put forward.By numerical simulation on energy loss in the bend with different curvature radii,arc length and friction coefficients in the open boundary condition,it is found that the changes of energy loss have the same tendency in the situation that curvature radii,arc length and friction coefficients are adjusted.The safe energy loss is always the smallest and ... |
