Geometric design is the assembly of the fundamental three-dimensional features of the highway that are related to its operational quality and safety. Its basic objective is to provide a smooth-flowing, crash-free facility. Geometric roadway design consists of three main parts: cross section (lanes and shoulders, curbs, medians, roadside slopes and ditches, sidewalks); horizontal alignment (tangents and curves); and vertical alignment (grades and vertical curves). Combined, these elements provide a three-dimensional layout for a roadway. This course is a summary of the design process for today’s roadway 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.
