The invention discloses a method for predicating traffic flow of a double-lane roundabout intersection with participation of signal lamps. The method comprises the following steps: 1, dividing the double-lane roundabout intersection into cellular spaces, and establishing a coordinate system; 2, marking vehicles, and establishing a random distribution vehicle arrival model with participation of signal lamps; and 3, introducing an advancing rule, a lane changing rule, a traffic flow parameter and the random distribution vehicle arrival model into a cellular automaton model, and predicting the traffic flow. The maximum value and the minimum value of the average speed of the vehicles running in the roundabout within a certain time period or the longest time and the shortest time of the vehicles running in the roundabout can be predicted, and method support is provided for active prevention and control of urban traffic congestion and energy management in vehicle running.

    本发明公开一种有信号灯参与的双车道环岛路口交通流预测方法,包括如下步骤:步骤一、将双车道环岛路口划分成元胞空间并建立坐标系;步骤二、将车辆进行标记,建立有信号灯参与的随机分布车辆到达模型;步骤三、将行进规则、换道规则、交通流参数和所述随机分布车辆到达模型引入元胞自动机模型,对交通流进行预测。本发明可以预测在某个时间段内,环岛内行驶车辆的平均速度的最大值和最小值,或车辆在环岛中行驶的最长和最短时间等,为城市交通拥堵主动防控以及车辆运行中的能量管理问题提供方法支持。
