This course is the first of two in this series that focuses on the geometric design of cross-sections for modern roads and highways. Its contents 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 roadway cross-sections. Upon course completion, the learner should be familiar with the general guidelines for roadway cross-section geometric design.

This course is intended to provide the learner with the following specific knowledge and skills:

Typical roadway cross-section elements

Components of the traveled way

Lane widths

Characteristics of roadway shoulders

Principles of road side design

Curb categories and usage

Rumblestrips

Design and application of on-street parking

Typical applications for drainage channels

Various types of traffic barriers

Noise reduction design

“Clearzone” concept
