基于运行速度的路线设计方法研究

Highway Alignment Design Method Based on Operating Speed of Vehicles

针对目前以设计速度为依据的公路线形设计方法存在的局限性,将运行速度与设计速度同时加以考虑,在此基础上,根据在公路上汽车的行驶特性和公路线形设计的要求,提出基于运行速度的公路路线设计方法及设计流程,为公路几何设计指标选取和运行速度设计方法的应用提供参考。

The existed shortage of highway alignment design based on design speed was analyzed. On this condition, two factors of design speed and operating speed were taken into consideration at the same time and according to operating characteristics of ear on road and the demand of alignment design, a new design method and design flow were introduced, which can be used as a reference for a design parameter of highway alignment.
