Better Roadway Design - Intersection Signalization

This course has been discontinued.

Roadway design is commonly based on minimum AASHTO (American Association of State Highway and Transportation Officials) and state DOT (Department of Transportation) design standards. However, these design standards are based on some assumptions of driver performance that may not be realistic, particularly as our population ages. The Federal Highway Administration has published a design handbook that provides substantially different guidance than that commonly prescribed by AASHTO and state DOT's.

This 2-hour interactive online course covers the subject of signalization for turning movements at roadway intersections in the FHWA document. The recommendations of FHWA can generally be implemented very economically. While the AASHTO and state DOT standards remain the minimum standards, the designer should recognize that they are just that - minimum standards. Designs can be improved by following the guidance in this course.

There is a test included at the end of this course.
