The invention provides a refinement estimation method, system and device for the remittable capacity of a highway lane, and a medium, and the method comprises the following steps: presetting the duration of a cycle period, and collecting the vehicle operation condition information of each lane on the highway in a target range in the current cycle period based on a highway full space-time perception method; obtaining the relative distance between adjacent vehicles on the same lane based on the vehicle operation condition information, judging the development situation of each relative distance, and obtaining the remittable capacity of each relative distance at the current moment; on the basis of the development situation and the current remittable capacity, screening out a remittable interval from the relative distances, and predicting the moment when the remittable interval moves to the confluence point of each downstream entrance ramp and the remittable capacity at the moment; by sensing the current situation and the development situation of the relative distance between the mainline vehicles of the expressway, the position and the capacity of the mainline vehicles in the confluence interval at the current moment can be obtained in real time, and the time and the capacity of the mainline vehicles moving to the downstream entrance ramp confluence point can be predicted.

    本发明提供一种高速公路车道可汇入容量精细化估计方法、系统、设备及介质,包括以下步骤:预设循环周期时长,基于高速公路全时空感知方法在当前循环周期内采集所目标范围内高速公路上各车道的车辆运行状况信息;基于车辆运行状况信息得到所有同一车道相邻车辆的相对间距,判断各相对距离的发展态势,并得到各相对距离的当前时刻可汇入容量;基于发展态势和当前可汇入容量在各相对距离中筛选出可汇入区间,并预测可汇入区间移动到下游各入口匝道合流点的时刻以及该时刻的可汇入容量;本申请通过感知高速公路主线车辆相对间距的现状及发展态势,不仅能实时获取主线车辆在当前时刻可汇入区间的位置与容量,还能预测其移动到下游入口匝道合流点时的时间与容量。
