7:45am - 4:00pm
Location Online - Course
This hybrid online class will combine both live instruction and independent online work that you will complete during the day. Independent work will include quizzes, readings, videos and short assignments. Access to a computer with a webcam (either a camera that is built into your laptop or one that connects via USB), a reliable internet connection and a workspace that is free from distraction and noise will set you up for success.
The unconventional intersection and interchange workshop offered the day prior to this lab will cover the fundamentals of unconventional intersections and interchanges in a lecture format. The purpose of the follow-up laboratory is to provide attendees the chance to work through hands-on examples and apply the principles discussed at the workshop. The lab will begin with a review of the tools on hand to analyze intersection and interchange alternatives. Then, each attendee will work on one surface-street intersection, one grade-separated intersection example, and one interchange example. Attendees will work together in small teams to develop potential solutions and then will discuss their potential solutions with the larger group. Cases examined during the lab are drawn from the ones that the instructor has worked on at the NCDOT; the cases are meant to be challenging, with no easy answers, but not impossible. By the end of the lab attendees should have the skills and confidence to tackle their own challenging intersection and interchange projects.
Module 1: Available Tools
Module 2: Intersection Case
Module 3: Grade-separated Intersection Case
Module 4: Interchange Case
Joseph E. Hummer
Joseph E. Hummer, PhD, PE, is the Staff Engineer in the Mobility and Safety Division of the North Carolina Department of Transportation (NCDOT). Joe is one of the foremost authorities on unconventional intersection and interchange designs practicing today. He began researching the designs in 1990, has published numerous articles about them, and has invented several new intersection and interchange designs. His two-part series in the ITE Journal in 1998 helped spark interest in the area. More recently, he was a co-author of the FHWA informational report on six of the most promising designs, he was the Principal Investigator of the FHWA research project investigating the effects of diverging diamond interchanges, and he was the primary author of the FHWA guidebook on superstreets. Joe was a Professor at North Carolina State University and was Chair of the Department of Civil and Environmental Engineering at Wayne State University before joining NCDOT in May 2016.
Who Should Attend
The case studies should again be of interest to any planners, designers, and operations professionals who work on intersections and interchanges. Laboratory attendees should have attended the unconventional intersection and interchange workshop the previous day or at some point in the past, or should have professional experience with intersections and interchanges. Attendees will need to apply basic math to the examples and should bring a laptop to the session to make the calculations easier.

Special Registration Instructions for Employees of the Virginia Department of Transportation
VDOT employees must register through the VDOT Virtual Campus. Registration fees and related expenses for all VDOT employees will be paid from the VDOT Learning Services Center budget. Registrants should contact their District Training Coordinator or the VDOT Learning Services Center (Central Office employees) for instructions on how to seek reimbursement for travel expenses.
Due to current travel restrictions, VDOT employees are strongly encouraged to attend U. Va. TTA workshops on a day trip basis. Overnight travel requires permission from your District Administrator or Chief -- and in some cases higher levels of authority. If you require overnight lodging to attend a U. Va. TTA workshop, consult with your supervisor, District Training Coordinator, or VDOT Learning Services Center on travel approval procedures.
