Pedestrian Crosswalk Safety: Evaluating In-Pavement, Flashing Warning Lights

Source: Federal Highway Administration, New Jersey Department of Transportation

"Accidents involving pedestrians on crosswalks are a common cause of road fatalities. In-pavement flashing warning lights have been proposed as a means of increasing the conspicuity of a crosswalk when a pedestrian is using it. Evaluations in California and Washington have demonstrated the effectiveness of such in-pavement flashing warning lights on moderating drivers' behavior when approaching a crosswalk. However, in-pavement flashing warning light systems are more expensive to install than striping, the conventional way of identifying crosswalks. This report describes work undertaken to determine the effect of an in-pavement flashing warning light system installed on a crosswalk on pedestrian safety, relative to striping."
