Rectangular Rapid Flashing Beacons

October 30, 2018, 1:00 PM to 2:30 PM Eastern Time

Register at:

In March 2018, the Federal Highway Administration (FHWA) issued a new Interim Approval (IA-21) for the use of rectangular rapid flashing beacons (RRFBs). This webinar will walk participants through the specifics of IA-21, focusing on the terms and conditions for installing new RRFBs. This will be followed by a short overview of when and where to install RRFBs, as well as a discussion period in which panelists will respond to questions submitted by participants.

This webinar supports FHWA's Safe Transportation for Every Pedestrian (STEP) program which promotes countermeasures at uncontrolled pedestrian crossings.
