The invention discloses an expressway traffic state determination method and system based on portal data, and relates to the technical field of traffic state detection, and the method comprises the steps: obtaining portal data at two ends of each road section in a target traffic corridor range in a target time period; splicing the portal data at the two ends of each road section to obtain traffic basic data; removing data of vehicles running at abnormal speeds in the traffic basic data to obtain a traffic data set; calculating the traffic volume and the average travel speed of each vehicle model of each road section according to the traffic data set; and calculating the traffic state index of each road section in a set time period according to the traffic volume and the average travel speed of each vehicle type of each road section. According to the invention, accurate detection of the traffic state of each road section is realized.
本发明公开一种基于门架数据的高速公路交通状态确定方法及系统,涉及交通状态检测技术领域,该方法包括:获取目标时间段内目标交通走廊范围内各路段两端的门架数据;对各路段两端的门架数据进行拼接处理,得到交通基础数据;剔除所述交通基础数据中异常速度行驶的车辆数据,得到交通数据集;根据所述交通数据集计算出各路段的各个车型的交通量和平均行程速度;根据各路段的各车型的交通量和平均行程速度计算出各路段设定时间段内的交通状态指数。本发明实现了各个路段交通状态的准确的检测。
