Crosswalk Flashing Beacons

City of Appleton, WI installs Carmanah's RRFB at a busy crossing near Lawrence University.

Supplementing crosswalk signs with an RRFB (Rectangular Rapid Flashing Beacon) has proven to increase safety and yield rates at uncontrolled crosswalks. It is one of the best and easiest ways to increase walkability in a community without significant infrastructure changes, and with Carmanah's solar RRFBs, installation is completed in minutes with little to no traffic interference.

On March 20, 2018, the Federal Highway Administration (FHWA) reinstated RRFB interim approval, making them once again MUTCD-compliant in the United States. Read more about the FHWA memorandum here.

RRFB Devices Offer Better Visibility

An RRFB uses high-intensity LEDs which are exceptionally noticeable by drivers during the day and evening. Their amber color and quick flash pattern make them easily visible in difficult night-time lighting conditions such as headlight glare and wet roads.

Studies have shown that rectangular rapid flashing beacons improved driver yield rates from 18% to up to 96%.

Building Crosswalks for Walkable Communities

Uncontrolled Crosswalks in These Areas Can Benefit

  • Intersections with thru-lanes on major legs
  • Urban mid-block crosswalks
  • Multi-lane crosswalk locations
  • Roundabouts
  • Trail crossings
  • Greenways
  • School zone crosswalks
  • University campus crosswalks

Why Install our Solar RRFBs at Crosswalks?

Crossing near school increases safety for children and the community.
