借助智能交通系统(ITS),把扩展的车辆跟驰模型应用于双车道,建立根据确定规则进行换道的扩展交通流跟驰模型.通过改变发车车头间距,在开放边界条件下左车道有交通事故发生时,重现实际交通中的交通流现象.数值模拟发现:双车道交通流模型能够有效地抑制交通流阻塞,提高交通流量.%The extended car-following model is applied into two-lane system based on intelligent transportation system application (ITS). Then, an extended model of two-lane traffic in which vehicles change the lane by a deterministic rule is presented. The typical traffic induced by a car accident on the left lane under the open boundary is investigated. The simulation results suggest that the two-lane traffic model can suppress the traffic jam and enhance the traffic flow effectively.
