Design and Demonstration of Pedestrian Waiting Time Countdown at Pedestrian Activated Signals

Pedestrian crashes have continually increased in Maryland over the last five years reaching 3,452 in 2017, 109 of which caused fatalities. According to Office of Traffic and Safety field studies at pedestrian-activated signal sites in Maryland, approximately 50% of pedestrians do not push the button. It is also found that approximately 25% of pedestrians fail to wait until the pedestrian signal turns to “Walk” even if they push the button for the activation. Crossing during the “Don’t Walk” increases the risk of pedestrian crashes since vehicles are not stopped. There is a need to conduct a study that evaluates the effects of a proposed countermeasure (i.e., wait time countdown) on pedestrian compliance; and designs the wait time countdown strategies including countdown numbers on the pedestrian signal, voice broadcast at the intersection, and notification on smartphones. The wait time countdown signal with different operational strategies would be demonstrated for its performance evaluation. The evaluation results could be used to justify the implementation of wait time countdown at pedestrian-activated signals. This countermeasure is expected to reduce the percentage of pedestrians who do not push the button or start crossing before the "Walk" phase. The wait time countdown can also potentially be added to smartphones so that pedestrians are efficiently notified.
