  • Abstract:
    The goal of this project was to develop implementation guidance that the Texas Department of Transportation ; (TxDOT) can use to make better decisions regarding the use of truck mounted changeable message signs ; (TMCMS) during scheduled and unscheduled operations. The objectives of the project were as follows: ; 1. Perform a nationwide survey with practitioners to determine the state-of-the-practice with regard to ; TMCMS and to identify what issues or hazards scheduled and unscheduled operations crews are ; encountering with regard to the motoring public. ; 2. Develop messages and application alternatives through the use of text or symbol combinations to address ; specific scenarios. ; 3. Conduct human factors comprehension studies. ; 4. Conduct field studies to determine the most promising message and application alternatives. ; 5. Develop guidelines to address the issues of design and application for the use of TMCMS. ; This project identified the types of messages/information that could be displayed on TMCMS for different ; situations, and also developed specific guidance for TxDOT on the use of TMCMS during scheduled and ; unscheduled operations.
