【摘要】 基于元胞自动机三相交通流Kerner-Klenov-Wolf(KKW)模型,研究开放边界条件下单向车道上车辆的油耗。车辆长度为15个元胞对应的相图分为畅通相、拥堵Ⅰ相、拥堵Ⅱ相和最大流量(MC)。通过分析交通局部密度和流量之间的交叉关联,确定了道路上游区域的同步流。数值计算了自由流、拥挤Ⅰ相、同步流(SF)和最大流量(MC)的油耗情况。计算结果表明,在开放边界交通系统中,驶入概率和驶出概率对油耗有较大影响。最大流量(MC)和拥挤Ⅰ相的交通油耗最高。同步流(SF)的油耗超过了自由流,但低于拥挤Ⅰ相和最大流(MC)的油耗。更多还原

【Abstract】 Based on the Kerner-Klenov-Wolf cellular automaton three-phase traffic model,we study fuel consumption of vehicles on one-way lanes under open boundary conditions.Phase diagram is divided into free-flow,congested phase I,congested phase II and maximum current phase.By analysis of the cross-correlation between local density and flow,synchronized flow on the area upstream of the road is determined.The numerical computations for fuel consumption on free flow,congested phase I,synchronous flow and maximum current are carried out.The results indicate that the injection rate and the removal rate have great impacts on fuel consumption in the open boundary traffic system.The maximum current phase and congested phase I maximizes fuel consumption.The fuel consumption of synchronized flow exceeds that of the free flow,but lower than that of the congested phase I and the maximum current.更多还原
