Instructional video for new RRFB


The Township of Russell in Ottawa, Ontario, installed Rectangular Rapid Flashing Beacons (RRFBs) at the Embryon Roundabout pedestrian crossover in 2022. This installation demonstrates how RRFBs function in roundabout environments, where continuous traffic flow makes pedestrian crossings particularly challenging.


RRFB Implementation How the System Works


The Russell Township RRFB system provides clear instructions for each user group.


Pedestrians

A pedestrian crosses a street with visible crossing signals and vibrant street banners, enhancing the safety.

  • Press the button to activate the flashing beacon

  • Make sure drivers can see you before stepping into the crosswalk

  • Cross only when traffic has fully stopped



Cyclists

Cyclists navigate a designated crosswalk, while vehicles wait, under clear signage ensuring safe passage.

  • Stop and get off your bike

  • Press the button to activate the beacon

  • Walk your bike through the crossover once cars have stopped


Drivers

Cars wait at a marked crosswalk as evening descends, illuminated by streetlights.

  • Must stop for pedestrians, whether the beacon is flashing or not

  • Continue through the roundabout after the pedestrian has crossed your lane


Why RRFBs Work


Research shows RRFBs significantly improve driver yielding rates compared to standard crosswalk markings. Studies indicate yielding compliance reaches 81-96% with RRFB installations, compared to 18-35% with regular crosswalks.

The system includes bright LED beacon arrays, push-button activation, and clear signage. The beacons are positioned for visibility from all roundabout approaches and activate only when needed.


Implementation Benefits


Russell Township's installation demonstrates several advantages:


Cost-Effective: RRFBs cost less than full traffic signals while providing measurable safety improvements.


User Education: The Township created instructional materials explaining proper system use.


Compliance: The installation meets Ontario Traffic Manual requirements for RRFB deployment.


Flexibility: Works well for roundabouts, mid-block crossings, and locations where full signals aren't needed.


Results and Applications


The Russell Township installation provides a reference for other municipalities considering similar pedestrian safety improvements. The system addresses pedestrian visibility challenges in roundabout environments while maintaining efficient traffic flow.


This type of installation works well for municipalities with roundabouts requiring pedestrian accommodation, mid-block crossing locations, or areas with documented pedestrian safety concerns.
