The Federal Highway Administration provided interim approval (IA-11) for the optional use of the rectangular rapid-flashing beacon (RRFB) at uncontrolled pedestrian and school crosswalks on Jul 16, 2008. Results from several studies showed widely varying driver yielding rates -- from a low of 19% to a high of 98%-indicating that there are characteristics other than the presence of RRFBs that have an effect on driver yielding. While several roadway, traffic, and traffic control device characteristics have been identified as being associated with the driver yielding, the characteristics investigated are not consistent between studies and do not fully explain the large range of yielding rates observed. The researchers believe that a larger dataset could provide an opportunity to identify the roadway or traffic characteristics present at a pedestrian crosswalk with an RRFB that are associated with high or low driver yielding. The research team used a staged pedestrian protocol to collect driver yielding data such that oncoming drivers received a consistent presentation of approaching pedestrians.
