摘要 为探究交织区不同车道分配方案对系统产生的影响效果,在Nagel和Schreckenberg提出的NS元胞自动机模型的基础上为三种不同换道区域定义了三种换道规则,建立针对交织区的元胞自动机模型。对比交织区是否设置隔离带的两种车道分配情况下交织区及非交织区分别进行了数值的模拟和分析,结果表明,流量低时,两种措施的效果无明显差异;流量较高并且交织比不大时设置隔离带将减少系统拥堵及各流向车辆的行程时间。当交织区的长度在一定值内,设置隔离带的效果更好,且随着交织区长度的增加,设置隔离带而产生的优化效果也越来越小。交织区超过这个长度后两种措施效果差不多。

英文摘要 This paper created a cellular automaton mode to explore the effects of different lane allocation schemes in the weaving area on the system. Based on the NS cellular automaton model for three different lane area defined three lane changing rules for weaving area of cellular automaton model. There have already been carried out numerical simulation and analysis of two lane allocation in weaving area. The results show that when the flow rate is low, no significant difference between the two measures of effect; when the flow rate is high, with travel time will reduce the system congestion and each set of vehicles to isolation. When the length of the weaving zone is within a certain value, the effect of isolating belt is better. With the increase of weaving area length, the optimization effect of isolation belt is becoming smaller and smaller. Weaving area over this length, the two measures almost have the same effect.
