基于高速公路联网收费数据OD合成及流向数据分析的交通量预测

Traffic Volume Prediction Based on OD Synthesis and Flow Data Analysis of Expressway Network Toll Collection Data

为了研究高速公路某断面的交通流量,通过对联网收费数据库的出入口刷卡时间、车型数据及收费站地理位置数据进行采集,提出了一种基于收费数据的道路交通流量的计算方法。首先提出了OD数据采集流程与处理,然后论述了OD合成及区域交通流向分析,最后设计了交通量预测方法与模型。该方法可对高速公路的任意断面进行较为高效准确的流量计算,可在交通规划、设计、管理、维修养护以及经济评价等方面。

In order to study the traffic flow of a certain section of a highway,a calculation method for road traffic flow based on toll data was proposed by collecting data such as entrance and exit swiping time,vehicle type data,and toll station geographic location data from an online toll database.The paper first proposes the process and processing of OD data collection,then discusses OD synthesis and regional traffic flow analysis,and finally designs traffic volume prediction methods and models.This method can perform efficient and accurate flow calculation on any section of the highway,and can be used in traffic planning,design,management,maintenance,and economic evaluation.
