20-3 Effectiveness of Rectangular Rapid Flashing Beacons (RRFBs) at Mid-Block Crosswalks

Project Dates: Jan 1, 2021 - Dec 31, 2022
Project Description:

Rectangular Rapid Flashing Beacons (RRFBs) are intended to improve pedestrian safety by providing supplemental emphasis to marked crosswalks. RRFBs consist of a pair of automatic or pedestrian activated flashing lights installed with a crosswalk warning sign. They are recommended for use in situations where increased visual emphasis is needed to alert drivers to an uncontrolled pedestrian crossing, such as a mid-block crossing. This project will study the design of mid-block crosswalks, collect and analyze data, and report on the findings of how RRFBs are implemented and whether their use is increasing the safety of everyone in the traveled way.
