The workshop covers the basic principles and concepts of geometric design of highways and intersections. Practical solutions and design techniques are emphasized. The workshop includes lectures and discussion and extensive hands-on workshop sessions dealing with alignment and cross-sectional design and intersection layouts and channelization. Workshop materials reflect the most recent AASHTO design criteria.
