Use of signs and symbols to increase
the efficacy of pedestrian activated flashing beacons at
crosswalks. Transportation Research Record, 1999. No. 1638,
This experiment evaluated two strategies for increasing
the percentage of motorists yielding to pedestrians at crosswalks
equipped with pedestrian activated flashing beacons. One
method involved adding an illuminated sign, with the standard
pedestrian symbol next to the beacons. The second method
involved erecting signs 50 m before the crosswalk that displayed
the pedestrian symbol and requested motorists to yield when
the beacons were flashing. Both interventions increased
yielding behavior and the effect of both together was greater
than either alone. However, only the sign requesting motorist
to yield when the beacons were flashing was effective in
reducing motor vehicle-pedestrian conflicts.
