About the research

Although the Manual on Uniform Traffic Control Devices (MUTCD) mandates temporary pedestrian accommodations when permanent facilities are disrupted, in practice, temporary accommodations for pedestrians, people with disabilities, and bicyclists are often inadequate or even nonexistent. Agencies need better tools to manage conflicts between motorized and nonmotorized traffic and reduce the rising number of non-motorist casualties in work zones.

The goal of this project is to investigate several accommodation techniques and develop guidance to assist agencies in applying them. The final list of techniques will be established in consultation with the SWZDI Board of Directors, and could include temporary curb ramps, options for managing vertical transitions, warning signage, and related items.
