This course is the first in a series of five volumes that summarizes and highlights the geometric design process for modern roads and highways. Subjects covered include: highway functions (classification systems); design controls and criteria (design vehicles, highway capacity, traffic characteristics); and elements of design (sight distance, horizontal and vertical alignments).  The course objective is to give engineers and designers an in-depth look at the principles to be considered when designing roadways.

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

This course is intended to provide you with the following specific subject matter:

• Roadway functional classification

• Design vehicle choices

• Driver performance

• Traffic characteristics

• Speed definitions

• Highway capacity

• Access control categories

• Pedestrian facilities

• Bicycle facilities

• Environmental influences

• Types of sight distance

• Horizontal alignment
