RRFBs are pedestrian-actuated enhancements used in combination with a pedestrian, school, or trail crossing warning sign to improve safety at uncontrolled, marked crosswalks. The device includes two rectangular-shaped yellow indications, each with an LED-array-based light source, that flash with high frequency when activated. The RRFB design differs from the standard flashing beacon by utilizing:
- A different shape
- A much faster rapid-pulsing flash rate.
- A brighter light intensity.
The installation of RRFBs can reduce pedestrian crashes by 47%, see NCHRP Research Report 841: Development of Crash Modification Factors for uncontrolled Pedestrian Crossing Treatments.
Remember, state law requires drivers to yield to pedestrians:
- Who have started crossing an intersection or crosswalk on a walk signal or on a green light if there is no walk signal;
- Who are crossing the road within a marked or unmarked crosswalk at an intersection where there are no traffic lights or control signals; and
- Whenever directed to stop by a school crossing guard (346.46 (2m). Like bus drivers, crossing guards have the authority to report violations to law enforcement.
