Abstract:A traffic control treatment being used at pedestrian-crossing locations is the pedestrian- or school-crossing warning sign with light-emitting diodes (LEDs) embedded in the borders (called LED-Em in this report). The LED-Em treatment, which includes a pedestrian pushbutton, is pedestrian activated, so the LEDs flashes only when a pedestrian is present. For this research study, researchers considered more than 7,800 drivers involved in more than 3,675 staged pedestrian crossings at 62 sites. The average driver-yielding rates at those sites were analyzed using analysis of covariance models. Logistic regression was also used to evaluate individual driver decisions on whether to yield or not to yield to a pedestrian. These analyses considered both roadway characteristics and traffic control device characteristics. The statistical analyses showed that posted speed limit, vehicle volume at the time of the crossing, crossing distance (roadway width), and the presence of supplemental traffic control devices influenced a driver’s decision to yield to a pedestrian attempting to cross a street when the LED-Em treatment was active. Higher posted speed limits, higher vehicle volumes, and longer crossing distances are associated with low driver yielding.
