车路协同下基于MPC的匝道合流控制方法研究

Control Method for Ramp Confluence Based on MPC Under the Environment of CVIS

为研究车路协同下匝道合流控制方法对于道路通行效率的作用,文中基于MPC的控制框架提出了CVIS环境下的匝道合流控制方法。考虑合流区特性和车辆行驶的约束,通过不断优化车辆行驶速度,为匝道车辆提供合适的可插车间隙,使得匝道车辆顺利合流。经仿真验证,提出的方法能够有效降低车辆行程时间,提高合流效率。

To study the effect of ramp confluence control methods on road traffic efficiency under the environment of CVIS,the control method of ramp confluence in CVIS environment is proposed based on the MPC control framework.Considering the characteristics of confluence and the constraints of vehicle moving,and providing acceptable gap for on-ramp vehicles by optimizing the vehicle running speed,the smooth merging of on-ramp vehicles can be realized.The simulation results show that the proposed method can effectively reduce the travel time of vehicles,improve the efficiency of confluence,and provide a method for relieving traffic congestion in ramp confluence area.
