The roadway horizontal alignment is a series of horizontal tangents (straight roadway sections), circular curves, and spiral transitions. It shows the proposed roadway location in relation to the existing terrain and adjacent land conditions. Together with the vertical alignment (grades and vertical curves) and roadway cross-sections (lanes, shoulders, curbs, medians, roadside slopes, ditches, sidewalks), the horizontal alignment (tangents and curves) helps to provide a three-dimensional roadway layout.
This 5-hour course is a summary of the design process for today’s roadway horizontal alignments. Participants will be given an in-depth look at the principles and potential trade-offs to be considered when selecting and designing roadways. By combining this course material with work experience and engineering judgment, the participant may produce plans beneficial to the traveling public.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
