摘要
为了进一步完善微观交通仿真中车辆换道行为模型,基于车辆换道行为过程中的不同情形,考虑待换道车辆换道意图产生与换道行为实施的时间关系,建立了综合性的车辆换道模型,该模型下车辆在不同条件时将分别执行自由换道及信息交互式换道。仿真中通过改变交通流密度和目标车道后车加速概率进行实验,结果表明,相对于其他换道模型,新模型使整个路段的交通流平均速度变大,在一定程度上能够减少路段交通拥阻,提高路段通行能力,新模型中换道行为规则更符合实际交通流状态。
Based on different situations of vehicles’lanes-changing process,considered the time relation between lane-changing intention appearance and lane-changing action implementation,this paper built the comprehensive lane-changing model. Respectively,executed the free lane-changing or lanes-changing from information interaction under different conditions. By changing traffic flow density and the acceleration probability of the rear vehicle on target lane,simulation results show that the new model improves the average speed of whole road section,and relieves road traffic congestion. The vehicle lane-changing rules in the new model are more in line with real traffic flow state.
