Roadway Geometric Design II: Cross-Sections and Road Types

COURSE NO: C06-017
COURSE PROVIDER: Gregory Taylor, P.E.
Roadway Geometric Design II: Cross-Sections and Road Types
Course Highlights

This online engineering PDH course focuses on the geometric design process for modern roads and highways. Subjects covered include: cross-section elements (lane widths, shoulders, roadside design, medians and drainage channels); local roads; collector roads; rural and urban arterials; and freeways. The course contents are intended to serve as guidance and not as an absolute standard or rule.


Geometric design is the assembly of the fundamental three-dimensional features of the highway that are related to its operational quality and safety. Its basic objective is to provide a smooth-flowing, crash-free facility. Geometric roadway design consists of three main parts: cross section (lanes and shoulders, curbs, medians, roadside slopes and ditches, sidewalks); horizontal alignment (tangents and curves); and vertical alignment (grades and vertical curves). Combined, these elements provide a three-dimensional layout for a roadway.


This 6 PDH online course is applicable to traffic and transportation engineers interested in learning about the principles to be considered when selecting and designing roadways.

Course Document

In this professional engineering CEU course, you need to review the course document titled “Roadway Geometric Design II: Cross-Sections and Road Types”. This course document is based exclusively on Chapters 4 through 8, Cross-Section Elements, Local Roads and Streets, Collector Roads and Streets, Rural and Urban Arterials, and Freeways, of the American Association of State Highway and Transportation Officials (AASHTO) publication, “A Policy on Geometric Design of Highways and Streets” (also known as the “Green Book”).
