Rectangular Rapid Flashing Beacons (RRFBs) 

Increase visibility and reduce pedestrian crashes at crosswalks up to 47% with high-intensity flashing LED light bars.

Crosswalks are a key aspect of walkability and they are growing more common at mid-blocks, roundabouts and unsignalized intersections. Stats on traffic incidents show the need for an effective solution to ensure all multimodal users stay safe. Carmanah’s RRFB systems feature ultra-bright lights to maximize pedestrian safety.

6,283

The number of pedestrians killed every year in motor vehicle crashes.

74%

The percentage of pedestrian fatalities that occur at non-intersections.

17%

The percentage of people injured in traffic accidents that were pedestrians.

18-28%

The effectiveness of crosswalk paint alone at stopping drivers when a pedestrian is present.

96%

The RRFB driver yield rate, compared to 18% with painted crosswalk only.

Supplementing crosswalk signs with an RRFB has been proven to increase safety and yield rates. This rapid flashing beacon is an improvement on the traditional crosswalk warning light because it uses high-intensity LEDs, which are exceptionally noticeable for drivers both during the day and at night. Their amber color and quick flash pattern (wig-wag + simultaneous or WW+S) make them easily visible when headlight glare, wet roads, or other situations create difficult nighttime lighting conditions. Studies have shown that the RRFBs can improve driver yield rates up to 96% and reduce crashes by 47%.

RRFBs are MUTCD-compliant. The Federal Highway Administration (FHWA) released Interim Approval 21 (IA-21) on March 20, 2018.

Problem Solution
Low yield rates at existing crosswalk. RRFBs get drivers to yield 73-96% of the time.
Low-intensity beacons are hard to see, especially during the day. RRFBs are directional, high-intensity lights that are visible at all hours (Class 1 in the Society of Automotive Engineers [SAE] Standard J595).
Drivers are used to existing beacons flashing on and off, so they no longer grab attention. The rapid flash pattern of the RRFB attracts driver attention (pattern is WW+S, or wig-wag + simultaneous).

How and where to use an RRFB

RRFBs are one of the best and easiest ways to increase walkability in a community without significant infrastructure changes. Explore our free RRFB Application Guide to design the layout of your RRFBs in multiple road scenarios and learn where they are best used.

A community toolkit for creating safer pedestrian crossings

In support of citizens, local groups, and elected officials advocating for safer local roadways, we’ve compiled a step-by-step Crosswalk Safety Guide and toolkit. Adding or improving crosswalks is one of the most effective ways for cities to achieve safe, walkable streets. It’s our hope this guide makes the crucial work of pedestrian safety a little less confusing and a little easier to implement. Get the Crosswalk Community Toolkit.
