The aim of this study was to identify opportunities to apply human factors principles and research to improve Ohio's transportation system. The Office of Traffic Engineering assigned thirteen topic areas to provide information and the study was limited to these topics even though there may have been other areas that are important from a human factors perspective. The topic areas included: rumble strips, changeable message signs (CMS), work zone delineation, half-size pavement markings, accident mitigation, older drivers, traffic signal operations, highway lighting, curve delineation, wet/dark delineation, raised pavement markings (RPM), information dissemination, and work zone safety. The aim was to identify opportunities to improve each of these areas by providing the human factors rationale and make recommendations to ODOT that can be adopted to improve Ohio's transportation system. For each topic area an extensive literature survey, using published documents as well as web-based sources, was conducted to identify research that has been done by others in the United States and in other countries. A statewide DOT survey was conducted to determine the best practices of other states with respect to each area. In addition, a product survey was conducted to identify promising new products. Based on this information, human factors opportunities in each area were identified. We found considerable information in the following topic areas: rumble strips and accident mitigation. Some information was found in the topics of work zone safety, changeable message signs (CMS), older drivers, work zone delineation, curve delineation, and information dissemination. Little information was available on raised pavement markings (RPM), highway lighting, traffic signal operations, half-size pavement markings, and wet/dark delineation.
