The invention discloses a method for determining the ramp flow of a ramp. The method comprises the following steps: acquiring first vehicle information of a floating vehicle in a preset target road section; for any preset target ramp, the following contents are executed: based on the position information, the number of first floating cars is determined, and the number of the first floating cars is the number of floating cars at the preset target ramp; second vehicle information and the number of second floating vehicles of the vehicles at the at least one detection position are obtained, and the second vehicle information at least comprises the main road flow; for any detection position, the permeability of the floating cars is determined based on the main road flow and the number of the second floating cars; and determining the ramp flow of the preset target ramp based on the first floating vehicle number and the permeability corresponding to at least one of the at least one detection position. Therefore, the ramp flow of the ramp is determined, and the accuracy of the determined ramp flow is improved.
本申请公开了一种确定匝道的匝道流量的方法,该方法包括:获取预设目标路段中浮动车的第一车辆信息;针对任一预设目标匝道,执行以下内容:基于位置信息,确定第一浮动车数量,其中,第一浮动车数量为预设目标匝道处浮动车的数量;获取至少一个检测位置处车辆的第二车辆信息和第二浮动车数量,其中,第二车辆信息至少包括主道路流量;针对任一检测位置,基于主道路流量和第二浮动车数量,确定浮动车的渗透率;以及基于第一浮动车数量和至少一个检测位置中的至少一者对应的渗透率,确定预设目标匝道的匝道流量。籍此,实现了确定匝道的匝道流量,提高了确定出的匝道流量的准确性。
