Roadway Geometric Design III - Intersections & Interchanges
In Roadway Geometric Design III - Intersections & Interchanges, you'll learn ...
- Elements of intersection design
- Types of grade-separation structures and where they are warranted
- Selection of the appropriate type of interchange and its essential elements
This course focuses on the geometric design process for modern roads and highways. Subjects covered include: intersections (types/examples, alignment, profile, sight distance, roundabouts); grade separations and interchanges (types, warrants, safety, economic factors). The contents of this course are intended to serve as guidance and not as an absolute standard or rule.
The course objective is to give engineers and designers an in-depth look at the principles to be considered when selecting and designing roadways. Upon course completion, you should be familiar with the general guidelines for roadway geometric design.
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, Chapters 9 and 10 – Intersections, Grade Separations and Interchanges will be used exclusively for fundamental roadway geometric design principles.
