基于运行速度的公路路线三维设计

鉴于公路线形设计中传统设计速度法的弊端日益显露，在总结分析国内外运行速度研究成果的基础上，结合交互式路线设计，将路线安全评价与CAD系统集成，完善了运行速度设计法，并进一步实现了基于运行速度的路线三维设计，能直观地对线形设计质量及行车安全进行检查与评价。

3D Design of Highway Route based on Running Speed

As more and more disadvantage of traditional design speed method appears in design of highway alignment, this paper summarizes and analyzes the research results at home and abroad based on the study of interactive route design, and takes route safety evaluation and route CAD system into integration, improves the running speed design method. It further realizes 3D design of highway route based on the running speed, making the inspection and evaluation on highway design quality and traffic safety directly.
