The invention discloses a method for determining an expressway lane management and control strategy based on a congested road section. The method comprises the steps: collecting traffic data through an expressway detector, and converting the queuing length into the traffic volume per unit hour; under the condition that the sum of the actual traffic capacity per unit hour of the congested road section and the traffic volume per unit hour converted from the queuing length cannot exceed the actual traffic capacity per unit hour of the downstream area, determining the saturation value of emergency lane opening of the congested road section; and determining an emergency lane opening end point according to whether the remaining unit hour traffic capacity of the downstream area under the condition that the emergency lane is not opened can meet the unit hour traffic volume of the emergency lane, and further determining the emergency lane opening length. According to the method, the vehicles in the congested road section can be timely dissipated, the highway traffic efficiency is improved, the open length of the emergency lane is reasonably determined, the waste of emergency resources caused by opening the emergency lane for a too long distance is avoided, and a scientific decision-making method is provided for opening the emergency lane to solve the traffic congestion problem.

    本发明公开了一种基于拥堵路段的高速公路车道管控策略的确定方法,通过高速公路检测器采集交通数据,将排队长度转换成单位小时交通量,在拥堵路段单位小时实际通行能力与由排队长度转换成的单位小时交通量之和不能超过下游区域的单位小时实际通行能力条件下,确定拥堵路段应急车道开放的饱和度值,根据下游区域在不开启应急车道情况下的剩余单位小时通行能力能否满足应急车道单位小时交通量来确定应急车道开放终点进而确定应急车道开放长度。本方法可以保证拥堵路段的车辆能够及时消散,提高了高速公路通行效率,合理确定应急车道的开放长度,避免过长距离开放应急车道导致应急资源的浪费,为开放应急车道解决交通拥堵问题提供科学的决策方法。
