一种基于收费数据的断面流量估算方法

高速公路的流量是反映高速公路交通状态的一个重要参数.目前,针对高速公路断面流量的采集主要依靠人工方式或者通过安装一些车流检测设备来获得,成本较高.结合高速公路收费系统的特点,通过对收费数据的统计分析,提出一种基于收费数据估算高速公路断面流量的方法.首先,对收费数据进行初步的处理,从中计算出行驶时间;然后,根据收费数据中的车辆信息统计出各个OD的交通流量;最后,结合各个收费站出入口的位置信息、路段行驶速度信息以及OD流量来估算断面的交通流量.

Sectional Flow Estimation Method Based on Data Charges

Traffic flow is an important parameter reflecting the state highway traffic.Currently,the methods of section traffic flow collection rely on manual mode and by installing some detection equipment,which methods' cost are high.With the characteristics of highway toll system,this paper proposed a method to estimate the highway section traffic based on the toll system data.First,processed the toll data and calculate the travel time.Then,counted the OD traffic flow.Finally,estimated the sectional flow according to the car speed and the location of toll.
