The invention discloses a vehicle dynamic merging control method and system for a mixed traffic flow. Comprising a virtual track determination module, a merging area positioning module, a pairing condition determination module, a merging vehicle pairing module and a vehicle merging control module. The virtual trajectory determination module determines instantaneous virtual trajectories corresponding to the main road vehicles and the ramp vehicles. And the merging area positioning module determines the coordinates of the intersection of the main road vehicle and the ramp vehicle through the instantaneous virtual trajectory, so as to position a safe merging area. And the pairing condition determination module determines a pairing condition according to the intersection condition of the instantaneous virtual tracks corresponding to the two continuous main road vehicles and the instantaneous virtual tracks of the ramp vehicles in the safe merging area. And the merging vehicle pairing module is used for pairing the main lane vehicles and the ramp vehicles according to the pairing conditions, and determining the main lane vehicles and the ramp vehicles participating in vehicle merging. And the vehicle merging control module selects a corresponding control strategy to perform merging control according to the vehicle types of the ramp vehicles and the main road vehicles in the vehicle combination.
本发明公开了一种混合交通流的车辆动态并线控制方法及系统。包括虚拟轨迹确定模块、并线区域定位模块、配对条件确定模块、并线车辆配对模块和车辆并线控制模块。虚拟轨迹确定模块确定各主道车辆和各匝道车辆对应的瞬时虚拟轨迹。并线区域定位模块通过瞬时虚拟轨迹确定主道车辆和匝道车辆的交叉点坐标,以此定位安全并线区域。配对条件确定模块通过两辆连续主道车辆对应的瞬时虚拟轨迹与匝道车辆的瞬时虚拟轨迹在安全并线区域内的交叉情况确定配对条件。并线车辆配对模块通过配对条件对主道车辆和匝道车辆进行配对,确定参与车辆并线的主、匝车辆。车辆并线控制模块根据车辆组合中匝道车辆和主道车辆的车辆类型选择相应的控制策略进行并线控制。
