Who should use IHSDM?
IHSDM is intended for individuals involved in the highway design process. That process includes project planning, preliminary engineering, final design, and design review. Prospective users include highway project managers as well as planning, design, safety, and traffic engineers in State and local highway agencies and engineering consulting firms. In addition, the transportation research and academic communities can use IHSDM in their studies and educational efforts regarding the safety and operational effects of highway geometric design.
