INVESTIGATION ON TRAFFIC FLOW CHARACTERISTICS AROUND A TYPE C WEAVING SECTION BASED ON CELLULAR AUTOMATON MODEL

Funds: The project was supported by the National Basic Research Program of China (2012CB725404), National Natural Science Foundation of China (10972135, 11172164), Innovation Program of Shanghai Municipal Education Commission (11YZ12) and Shanghai Program for Innovative Research Team in Universities.
  • 摘要: 根据C型双侧交织区的车辆换道特征建立相应的换道规则,采用多车道元胞自动机模型研究交织区系统的交通流特性. 通过数值模拟得到了不同交织区长度下的相图,表明当主路和匝道交通流均为自由流时,交织区长度对系统影响不大,但当主路或匝道拥挤时,交织区长度的增加可以明显改善入口匝道的交通流状况. 进一步讨论了主路畅通而交织流量较大情形下主路上的车辆密度、速度和换道频率分布,发现换道集中在合流区和分流区附近,并造成相应路段上的局部拥堵.
