| 摘 要： | 山岭区高速公路行车速度受纵坡影响较大,与其他区域高速公路有着明显的不同,我国目前还没有一个针对山岭区高速公路运行速度的预测模型。在分析国内外相关研究成果的基础上,选择三福高速公路、渝宜高速公路、渝成高速公路、渝黔高速公路、渝武高速公路5条山岭区高速公路作为运行速度的调研对象,共计收集156处的道路线形数据和运行速度数据。通过分析速度与线形之间的分布特性,建立了山岭区双向4车道高速公路运行速度预测模型。使用156处数据对模型进行了标定,分别得到小客车、货车运行速度预测模型。

| Abstract: | The expressway in mountain area,which Slope has a important influence on the running speed,have an obvious difference with expressway in other area.At present,there are no operating speed model of four-line expressway in mountain area yet.After analyz- ing the research result abroad,San-Fu,Yu-Yi,Yu-Wu,Yu-Cheng and Yu-Qian expressway are chosen as research subject,align- ment data and operating speed data are collected from 156 places.Through analyzing the distributing characteristic between speed and alignment,the operating speed model of four-line expressway in mountain area is set up.The car and truck operating speed models are obtained by demarcating with the abovementioned data. |
