Many factors influence the selection of the appropriate type of system interchange: character and composition of traffic, speed considerations, environmental constraints, safety and operational benefits, right-of-way constraints, and cost. This workshop introduces the basic forms of system interchanges and an interchange selection procedure applicable in both urban and rural areas, shares the latest information from research focused on system interchanges, and features a facilitated discussion on system interchange research needs. Also included is a case study of an interchange selection project, allowing participants to actively apply lessons learned in the workshop.

This workshop follows the recent rescission and reinstatement of the rectangular rapid flashing beacon in the Manual on Uniform Traffic Control Devices, as well as the release of new crash reduction factors and FHWA implementation guidance for crosswalk treatments. The workshop will include a panel presentation with case studies, small-group discussions of best practices and research gaps, and a training on the new FHWA crosswalk guidelines that includes a hands-on group exercise. B&N’s Amy Rosepiler will moderate this session presented by Meghan Mitman from Fehr & Peers.
