The invention discloses an expressway section traffic volume prediction method, medium and system, and the method comprises the steps: obtaining the traffic volume survey data of a to-be-measured road section of an expressway, including the number of vehicles going from an entrance in the to-be-measured road section to an exit in the to-be-measured road section within a preset time period, and the number of vehicles going from an exit in the to-be-measured road section to an exit in the to-be-measured road section; the number of vehicles going from an entrance outside the to-be-measured road section to an exit inside the to-be-measured road section, the number of vehicles going from an entrance inside the to-be-measured road section to an exit outside the to-be-measured road section, and the number of vehicles going from an entrance outside the to-be-measured road section to an exit outside the to-be-measured road section; according to the traffic volume survey data, respectively calculating the traffic volume of each entrance and each exit in the to-be-measured road section and the traffic volume of the entrance outside the to-be-measured road section; and calculating the traffic volume of each section of the to-be-measured road section according to the traffic volume of each entrance and each exit in the to-be-measured road section and the traffic volume of the entrance outside the to-be-measured road section. According to the method, the section traffic volume of the corresponding road section can be accurately estimated by using the data of the expressway entrance and exit.
本发明公开一种高速公路断面交通量的预测方法、介质及系统,包括:获取高速公路的待测路段的交通量调查数据,包括:预设时长内从待测路段内的一入口去往待测路段内的一出口的车辆数,从待测路段外的入口去往待测路段内的一出口的车辆数,从待测路段内的一入口去往待测路段外的出口的车辆数,从待测路段外的入口去往待测路段外的出口的车辆数;根据交通量调查数据,分别计算待测路段内的每一入口和每一出口的交通量,以及,待测路段外的入口的交通量;根据待测路段内的每一入口和每一出口的交通量,以及,待测路段外的入口的交通量,计算待测路段的每一断面的交通量。本发明利用了高速公路出入口的数据,可精确地估算相应路段的断面交通量。
