The
Influence of Signs Prompting Motorists to Yield Before Marked
Crosswalks on Motor Vehicle - Pedestrian Conflicts at Crosswalks
with Flashing Amber. Accident Analysis and Prevention, 1992,
24, 217-225.
Abstract
The purpose of this experiment was to evaluate the effects
of signs reading “STOP HERE FOR PEDESTRIANS” along
and in conjunction with advance stop lines on pedestrian
safety at multilane crosswalks with pedestrian-activated
amber flashing lights. Motorist and pedestrian behaviors
measured throughout this experiment included the occurrence
of various types of motor vehicle-pedestrian conflicts;
the distance that motorists stopped before the crosswalk
when yielding to pedestrians; and the percentage of motorists
yielding to pedestrians. The introduction of the sign alone
50 feet (15.15 M) before the crosswalk increased the distance
before the crosswalk that motorists yielded to pedestrians
and reduced the percentage of motor vehicle-pedestrian conflicts
whether the flashing light was activated or not. The addition
of the advance stop line was associated with further improvements
in both measures.
