    Brief Project Description & Background
    The Manual on Uniform Traffic Control Devices, (MUTCD), and AASHTO’s Roadside Design Guide both contain general guidelines for truck mounted attenuators (TMAs); however neither of these references include recommendations for marking design and color for these devices. The objective of this study is to evaluate public and worker perception of the effectiveness of various design patterns and color combination for truck mounted attenuator markings.
    Research Objective
    The objective of this study is to evaluate public and worker perception of the effectiveness of various design patterns and color combination for truck mounted attenuator markings. To do so, we plan to synthesize common practices of state departments of transportation (DOTs) in regard to TMA color and design options used. In addition, the study would evaluate public and worker perception of the effectiveness of various design patterns and color combinations for TMA markings. Evaluation methodology will include surveys and actual field condition observations.
    Potential Benefits
    The result of this study will lead to increased safety, reduced fatalities and fewer crashes.
    Abstract
    The objective of this study is to evaluate public and worker perception of the effectiveness of various design patterns and color combinations for truck mounted attenuator markings. Evaluation methodology will include surveys and actual field condition observations. Of concern is the use of downward facing stripes when following vehicles do not have the option of passing on both sides of the work vehicle. The impact of background contrast from truck color will also be considered in evaluating the effectiveness of the various markings.
