| 摘 要： | 在充分研究国内外关于运行速度预测方法的基础上,以北京黄关公路为研究对象,基于实测运行速度并结合山区双车道公路的特点,回归以路线平、纵面的主要参数为变量的运行速度预测模型,并以实测运行速度验证预测模型的有效性。该模型合理、实用,可为开展基于运行速度的山区双车道公路安全性评价提供依据。

| Abstract: | Based on the study of forecasting methods of speed at home and abroad,taking Huangguan Road as the study object,speed prediction model is regressed by the main parameters of plane and vertical surface of lines according to the measured speed and the characteristics of mountainous two-lane highway.The validity of predictive models is verified by measured running-speed.This model is reasonable and practical,which can provide basis for the safety evaluation of mountainous two-lane highways. |
