元胞自动机慢启动规则交通流模型的能耗研究

Effect of initial conditions on energy consumption in cellular automata traffic model with slow-to-start rules

文章对TT、BJH和VDR 3种典型的慢启动规则元胞自动机交通流模型的能耗和能量耗散进行了研究,通过分析NaSch模型车辆在加速、确定减速和随机减速3个过程的做功,提出元胞自动机交通流模型的平均能耗公式和平均能量耗散公式,通过数值模拟分别讨论了在周期边界条件下车辆的能耗和能量耗散。结果表明,车辆的加速的能耗和减速的能量耗散相等,能耗和能量耗散与车辆初始分布的状态和演化规则有关。

Energy consumption and dissipation in TT,BJH and VDR models with the ＂slow-to-start＂ rule were studied.The new formulas of energy consumption and dissipation were presented,and the energy consumption was investigated.Numerical results showed that the energy consumption caused by acceleration of vehicles was equal to the energy consumption caused by deceleration of vehicles and the energy consumption and dissipation were related with the initial condition and the rules of traffic.
