Overview
The purpose of this study was to identify how safety and public service announcement (PSA) messages influence driver behavior and to ultimately assist the U.S. Department of Transportation (USDOT), transportation management centers (TMCs), state agencies, and local transportation partners in optimizing the utility of safety and PSA messages on DMS. Four urban areas in the United States were selected as study sites—Chicago, IL; Houston, TX; Orlando, FL; and Philadelphia, PA. Surveys were designed to specifically address the types of safety and PSA messages for each respective city. The goal was to collect approximately 500 survey responses per city. In total, 2,088 responses were received.
