基于断面流量的交通量调查数据拟合分析及应用研究

Fitting Analysis and Application Based on Traffic Volume Survey Data traffic section

随着交通信息化的发展,交通流量自动调查站点已经成为道路交通流量数据采集的主要手段。但交通流量自动调查站点所采集到的流量数据为道路断面流量,而我们在进行交通量统计分析应用时,往往面临需要对路段、道路甚至一个地理区域内的若干交通量调查站点进行统一测算并进行分析应用。本文以云南省为例,从实际需求出发,探讨基于若干个交通流量自动调查站点,把断面流量拟合为路段、道路以及区域的流量折算方法。并基于该方法,阐述了拟合后的数据分析应用,对交通量数据统计分析和深入挖掘进行研究。

With the development of traffic information, traffic automatically survey the site has become the primary means of road traffic data collection. However,traffic is automatically collected to investigate the site of a road section of traffic flow data,and we conduct traffic statistical analysis applications,are often faced with the need for the road,and even a number of road traffic survey sites within a geographic area and unified estimates analyze application. Taking Yunnan Province,starting from the actual demand,to explore a number of traffic- based automated site survey, the cross- sectional flow fitting converted into road traffic, road and regional approach. And based on this method, it describes the data analysis applications after fitting,statistical analysis of traffic data and dig deeper research.
