弹性系数法在公路工可交通量预测中的应用

运用弹性系数法进行交通量预测的关键在于确定弹性系数。文章选取交通区汽车保有量、客货运输量、通道交通量统计资料与国内生产总值作为弹性系数指标，进行回归确定弹性系数。通过资泸路（省道207线）威远段改造工程工可交通量预测，验证了弹性系数指标选取的正确性和预测结果的合理性，对公路工程可行性研究交通量预测具有广泛的应用价值。

Application of Elastic Method of Traffic Volume Forecasting in Estimating the Feasibility of Highway Project

The elastic method is one combined predicting approach in quality as well as in quantity.The key issue for using the elastic method in the traffic volume forecasting is the determination elasticity coefficient.This paper chooses automobile existing quantity,passengers and cargo freight volume,the channel volume of traffic statistical data and GDP of communication zone as the index of the coefficient of elasticity,to determination elasticity coefficient through return forecast.This method is utilized in(provincial road 207) the Weiyuan section in feasibility research of highway project.The given example verifies the correctness of elastic method,and has reference value for the traffic volume forecasting.
