CE73.40 : Advanced Geometric Design and Highway Safety  3(3-0)
 
Course objectives:

The course aims to provide students with an understanding of the basic principles and techniques of highway design. In addition, the course will teach the theory and criteria of geometric design of rural urban and rural roads, and the safety aspects.
 
Learning Outcomes:

Advanced concept of the design of urban and rural roads, design controls and criteria, highway alignment, cross section, intersection, interchange, and safety effectiveness of geometric design.
