Roadway Cross-Sections

Gregory J. Taylor, P.E.

The AASHTO “Green Book” defines a roadway cross-section as “a vertical section of the ground and roadway at right angles to the centerline of the roadway, including all elements of a highway or street from right-of-way line”. Along with the vertical alignment (grades and vertical curves) and horizontal alignment (tangents and curves), the roadway cross-section (lanes and shoulders, curbs, medians, roadside slopes and ditches, sidewalks) helps to present a three-dimensional roadway model. Its ultimate goal is to provide a safe, smooth-flowing facility that is crash-free.

This 6-hour course is a summary of the design process for today’s roadway cross-sections. Participants will be given an in-depth look at the principles and potential trade-offs to be considered when selecting and designing roadway cross-sections. By combining this course material with work experience and engineering judgment, the participant may produce plans beneficial to the traveling public.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
