Joe Hummer is a Professor of Civil, Construction, and Environmental Engineering at North Carolina State University, where he has taught and researched highway design, safety, and operations since 1992.  He previously taught at UNC Charlotte, worked for a transportation engineering consulting firm, and served as a Graduate Research Fellow at FHWA.  Joe has a PhD from Purdue and MS and BS degrees in civil engineering from Michigan State.  He is a registered Professional Engineer in North Carolina.  His research specialty is the design and operation of unconventional intersections and interchanges, such as superstreets, continuous flow intersections, auxiliary through lanes, two-level signalized intersections, and diverging diamond interchanges; he has worked on them for over 20 years.  Joe has developed four new designs, has published numerous papers in this area, and has taught many seminars and courses on these designs.  He has made extensive contributions in highway safety, including investigations of red-light running and speed cameras, brighter signs, brighter pavement markings, pedestrian warning signs, and railroad grade crossing devices.  Joe has also conducted research in highway capacity analysis, asset management, and project cost estimation.
