智能网联试验场环岛智慧管控策略应用研究

Research on the Application of Intelligent Control Strategy at Roundabout of ICV Proving Ground

文章通过分析智能网联试验场环岛测试场景车辆到达模型,研究了环岛信号控制的三种模式,建立了智慧管控策略信号配时模型,运用目标函数最优解的方法,得出单一信号控制、左转两部信号控制及左拐独立信号控制环岛的通行能力。研究结果表明,在车流量较大时,左转两部信号控制及左拐独立信号控制的配时方案能够显著解决环岛拥堵问题,证明了环形交叉口信号控制策略的有效性。

By analyzing the vehicle arrival model of the island round test scene in the intelligent network test site,this paper studies three modes of island round signal control,establishes the signal timing model of intelligent management and control strategy,and uses the optimal solution of the objective function to obtain the traffic capacity of the single signal control,the two-part signal control and the single left signal control of the island.The results show that when the traffic flow is large,the timing scheme of two-part left turn signal control and single left turn signal control can significantly solve the congestion problem of the roundabout,which proves the effectiveness of the signal control strategy of the roundabout.
