Development and Presentation of a Roadway and Roadside Design Course

摘要

The overall goal of this course is to provide training in the elements of geometric highway design. Specific course objectives are: (1) To review the geometry of horizontal and vertical alignment including simple circular curves, compound curves, tapers, and vertical curves. (2) To present the concepts of highway design as presented in A Policy on Geometric Design of Highways and Streets (AASHTO Green Book, 2004) including functional classification, sight distance, superelevation, cross section elements, design standards, and controls for horizontal and vertical alignment. (3) To present current information and operating practices related to roadside safety as described in Roadside Design Guide (AASHTO, 2002) including, the clear zone concept and slope design. (4) To present Alabama Department of Transportation operating practices with respect to location and design elements. (5) To present a typical roadway and roadside design workflow.
