近年来,公路部门对新建和改建工程正在搞可行性研究,感到正确推算公路远景交通量的重要性。如何正确地去推算符合我国国情的远景交通量,以往缺少有效方法。近年人们已经注意到了交通量的发生与许多因素(诸如汽车拥有量、工农业产值、人口数、货物周转量以及养路费等)有关,从而有可能用数理统计学中的回归分析方法来建立交通量与这些因素间的相关关系。本文就是试用回归分析方法来对公路远景交通量的推算作一探讨。
In recent years, the highway department is conducting feasibility studies on new construction and reconstruction projects and feels the importance of accurately projecting the traffic volume of highway prospects. How to correctly calculate the long-term traffic in line with China’s national conditions, the past lack of effective methods. In recent years, it has been noticed that the traffic volume is related to many factors such as car ownership, industrial and agricultural output, population, cargo turnover and road maintenance, etc. It is thus possible to establish traffic using regression analysis in mathematical statistics The relationship between quantity and these factors. This article is a trial regression analysis method to predict the highway traffic volume to explore.
