Best Practice Guidelines for Intelligent (Active) Warning Devices

Summary:

Local agencies receive requests for various intelligent safety technologies (active warning devices) like Rectangular Rapid Flash Beacon (RRFB), Speed Radar Signs, LED Stop Signs, etc. With these devices being relatively new, agencies are looking for guidance on whether they are effective, when and where to install, what protocols/guidance are available, what are other agencies experiences, etc. Deliverables anticipated for this project include: • A reference guide that addresses the issues/questions listed above for each of the various intelligent warning devices, which could be a combination of a quick reference guide/matrix and a one-page fact sheet for each device that could be used to help respond to residents and others who ask for these tools. • A matrix for engineers to use in making decisions on where to install.

Final Deliverables:

• Guidelines for Using Intelligent Warning Devices (Report #2023RIC02)
