Increase visibility and reduce pedestrian crashes at crosswalks up to 47% with trusted, MUTCD-compliant technology.

Safe and frequent crossings are a key feature of walkable, livable communities—and not just at signalized intersections. Midblock crosswalks and marked crosswalks at roundabouts and other unsignalized locations can provide numerous safety benefits to pedestrians.

The inclusion of RRFBs in the MUTCD 11th Edition (2023), is an exciting step forward for road safety regulations.

The best way to optimize visibility and safety at these crossings is with Carmanah’s MX Series rectangular rapid flashing beacon (RRFB) – R920-MX

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


The percentage of people injured in vehicle crashes that were travelling on foot.


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


The RRFB driver yield rate, according to the FHWA.

RRFBs are a widely-used and highly effective treatment. Their amber color and erratic flash pattern are proven to capture drivers’ attention, increasing yield rates by up to 98% and reducing crashes up to 47%, according to the FHWA. They meet MUTCD Standards and are a Proven Safety Countermeasure promoted by the Safe Transportation for Every Pedestrian (STEP) initiative.

Problem Solution
Low yield rates at existing crosswalk. RRFBs get drivers to yield up to 96% of the time.
Low-intensity beacons are hard to see, especially during the day. RRFBs use directional, high-intensity LEDs that are visible at all hours (SAE Standard J595 – Class 1).
Drivers are used to flashing beacons, so they no longer grab attention. The erratic wig-wag + simultaneous flash pattern of the RRFB attracts driver attention.
Signal techs are reliant on the public to call in downed or damaged infrastructure. MX RRFBs alert personnel as soon as there’s an issue, be it a knockdown, low battery, or something else.
Engineers have limited insight into the adoption and/or effectiveness of their systems. MX Cloud provides easy access to data like pedestrian counts that can be used to assess effectiveness and make decisions about future infrastructure.

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 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. It’s our hope this guide makes the crucial work of pedestrian safety a little less confusing and a little easier to implement.
