The concept of horizontal and vertical curves in roadway design is new to almost all students that enter the Highway Drafting and Route Design course. There are a numerous design characteristics and equations to remember. To aide in describing the horizontal curve of a roadway, Sandra Bowling presented a road model using the Micro Chargers race track that identified the characteristics of the various types of horizontal curves . After reviewing the horizontal curve components, the students were put into teams and given their own Micro Charger race tract to create a roadway and identify all the characteristics of the horizontal curve.
