Increase visibility and improve driver yield rates at crosswalks with high-intensity flashing LED light bars.

Crosswalks are a key aspect of walkability, and they are growing more common at mid-blocks, especially in areas with a lot of foot traffic. Stats on traffic incidents at mid-blocks show the need for an effective solution to ensure all multi-modal users stay safe.

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

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%.

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).

Design your roadway layout with RRFBs

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.

Put our solar and AC-powered RRFB to use at crosswalks

Watch our RRFB overview video to learn exactly where and how a rectangular rapid flashing beacon can be installed. Here are some highlights:

 

  • RRFBs are ideal at urban mid-block crosswalks, unsignalized intersections, roundabouts, and more
  • RRFBs can be installed on existing sign posts without the need for specialized equipment
  • A solar-powered RRFB installs without costly trenching or long traffic delays

Are RRFBs MUTCD-compliant?

Yes. The Federal Highway Administration (FHWA) released Interim Approval 21 on March 20, 2018, which makes the RRFB MUTCD-compliant in the US. RRFB Interim Approval 11, the original RRFB interim approval, was rescinded in December 2017. With IA-21 now in place, state and local agencies can apply for interim approval. Read more about the FHWA memorandum.

Curious about connectivity?

We partnered with leading intelligent transportation systems (ITS) solutions provider Applied Information to develop StreetHub, a portfolio of beacons and signs that leverages cellular technology to allow authorized personnel to remotely monitor and control their complete network from a single easy-to-use web-based platform. With StreetHub, you can monitor your RRFBs from anywhere, plus collect data, manage alerts, and more—all without having to make a manual site visit.
