Alternative Interchange & Intersection Design
June 29, 2020 @ 7:45 am - 4:00 pm EDT
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.
Many arterials and interchanges are terribly congested, and conventional measures offer little prospect for relief. Unconventional designs offer some potential for relatively inexpensive improvements to those congested arterials and interchanges. These are designs that have been used in some state or have been researched but have not been placed into widespread use. Examples include the superstreets (RCUTs, j-turns) being installed in North Carolina, the median u-turns that Michigan has used for many years, and the diverging diamond interchanges that have recently opened in over 20 states. In the right place with the details designed well, an unconventional design can deliver safety, efficiency, environmental, and cost benefits to motorists and transportation agencies.
The purpose of this workshop will be to discuss the best of the unconventional intersection and interchange options in some depth. We will explore the history, planning, design, and operation of the major designs. By the end of the workshop attendees should understand which design has a realistic chance to help in a particular spot.
