Transportation Engineering: Geometric Design of Highways
This interactive online course presents elements of design of the geometry of roads and highways. In this course, we will cover horizontal and vertical alignment design as well as the type of curves and principles for designing them that are safe, cost-effective, and comfortable for motorists. You will learn how to integrate horizontal and vertical alignment, the elements of roadway cross-sectional elements, and how to design roadside features and appurtenances. Note: it will help to have a calculator handy while taking this course.
- Describe the fundamental principles of roadway geometry and how it contributes to efficient traffic conditions and safety.
- Describe the elements of the design of safe, comfortable, and aesthetic roadway alignments.
- Analyze and perform calculations on properties of horizontal and vertical curvature of roads and highways to provide a path in a safe and efficient manner that is compatible with the environment.
- Describe the principles guiding the selection of road cross section elements such as lane widths, curbs and shoulders of roads and evaluate potential adverse impacts on safety.
- Describe the principles guiding the application of roadside features such as roadside slopes, medians, and longitudinal barriers and how they impact the safety and functionality of roads.

A good overview of the material. there appears to be an error in the answers given to problem 11. I believe the answer is 965 feet but have chosen 906 feet as it is the closet fit.

Would have been better to clarify not only the derivation of equations but also on the units used. I experience frustration if determining when to use percentages and when to use decimals in the horizontal and vertical geometry calculations. This required more time to figure out than the subject matter warrants. Otherwise a good presentation of a broad topic.
