The invention discloses a ramp priority space-time cooperative control method for a highway ramp confluence area. The method comprises the following steps: determining a safe distance between a ramp vehicle and main line vehicles and a safe distance between the main line vehicles through a defined safe distance calculation formula, then calculating a conflict urgency degree, then identifying the main line vehicles possibly conflicting with the ramp vehicle, and determining a target gap between the main line vehicles. According to the cooperative control method for formulating ramp priority according to the determined target gap, the driving track of vehicles involving conflicts is compiled in advance, and a method for compiling the vehicle driving track in advance before the ramp vehicles converge is provided, so that the ramp vehicles can smoothly and safely converge to a main line according to the preset tracks, and the traffic safety of the vehicles is improved. Therefore, traffic conflicts are effectively reduced, and the confluence efficiency is improved.
本发明公开一种高速公路匝道合流区的匝道优先时空协同控制方法。通过已定义的安全距离计算公式确定匝道车辆与主线车辆之间以及主线车辆与主线车辆之间应保持的安全距离,然后计算冲突紧要程度,再识别可能与匝道车辆产生冲突的主线车辆,并确定这些主线车辆之间的目标间隙。根据确定的目标间隙制定匝道优先的协同控制方法,预先编制涉及冲突的车辆的行驶轨迹,提出一种匝道车辆在合流之前预先编制车辆行驶轨迹的方法,使得匝道车辆能够根据这些预设的轨迹顺利且安全地合流到主线,从而有效地减少了交通冲突,提高了合流效率。
