    Development of Discrete Size Measurement Methodologies for Motorcycle Helmets
    Wietholter, Kedryn ;
    Rains, Corinn
    2023-09-01 | PDF
    FMVSS No. 218 defines the discrete size of a motorcycle helmet and requires it on the label; however, it does not specify how to measure the size. In addition, there is no standard procedure for determining the helmet positioning index (HPI) used to align the helmet on the headform for measurements and testing. This research developed procedures to ...

  • HeadUp Displays and Distraction Potential
    Head-Up Displays and Distraction Potential
    Russell, Sheldon M. ;
    Radlbeck, Joshua
    2023-01-01 | PDF
    Head-up displays (HUDs) present opportunities and challenges for mitigating driver distraction. HUDs may improve safety by reducing the time required to view driving-related information relative to a traditional head-down display (HDD). However, because the HUD is in the driver’s field of view, drivers may fixate on it and fail to perceive events i ...
