Roadway Vertical Alignment | PDH Library
Author: Gregory J. Taylor, P.E.
In today’s environment, designers must do more than apply design standards and criteria to ‘solve’ a problem. They must understand how various roadway elements contribute to safety and facility operation, including the vertical profile.
This course focuses on the geometric design of vertical alignments for modern roads and highways. Upon course completion, you should be familiar with the general design of these alignments. The course objective is to give engineers and designers an in-depth look at the principles to be considered when designing roadway vertical alignments.
A Policy on Geometric Design of Highways and Streets (also known as the “Green Book”) published by the American Association of State Highway and Transportation Officials (AASHTO) is considered to be the primary guidance for U.S. roadway design. For this course, Chapter 3 (Section 3.4 Vertical Alignment) will be used exclusively to present fundamental roadway geometric design principles.
