The National Highway Traffic Safety Administration (NHTSA) develops, promotes, and implements programs with the goal of ending preventable tragedies and reducing economic costs associated with vehicle use and highway travel. This project supports NHTSA�s development of effective highway safety countermeasures by improving the methods used to measure community traffic safety attitudes in program evaluations. The models of change that underlie many of NHTSA�s successful countermeasures rely upon increased awareness or other changes in attitudes. As such, evaluations of the effectiveness of proposed countermeasures often require repeat measures of traffic safety attitudes to determine whether the program is having the intended effect. The objective of this project is to assist NHTSA in conducting a systematic literature review to identify the most well-designed and feasible non-probability-based survey sampling methods and surrogate data sources for measuring change in public attitudes. Based upon the review, the project will produce detailed methodology plans for administering and validating the highest ranked methods, but it will not involve conducting the surveys. The downstream goal of this research is to give the traffic safety community realistic tools for building effective programs by modernizing and validating affordable methods for detecting change in community traffic safety attitudes. |
