Abstract\u003Cbr>This project develops capability for future studies on the effects of nontraditional messages in dynamic message signs on improving driver safety and compliance and avoiding distractions. An online survey and a driving simulation game were designed, and a pilot run was conducted with a small number of students in the University of Illinois Urbana Champaign. Survey responsesand simulation data were analyzed to reveal preliminary findings on notable effectiveness across different types of messages (e.g., humorous, emotionless, negative) . The pilot study also provides guidelines and recommendations for running a large-scale survey and simulation game in the future. |  |  |  |  |  |  |\n| 17.
