Abstract:An independent evaluation of a set of novel prototype mirrors was conducted to determine whether the mirrors perform as well as traditional production mirrors across the basic functions of field of view (FOV), image distortion, and distance estimation. Driver acceptance of prototype mirrors was evaluated, as well. The study involved a controlled test with research staff and a static evaluation with recruited participants on the Virginia Smart Road’s static test area (STA). Controlled testing determined capabilities by assessing the maximum FOV presented to specific individuals. The static evaluation allowed participants to provide feedback regarding the prototype mirrors. Driver ratings indicated a preference for the way production mirrors handled image distortion and an overall preference for production mirrors on trucks. Analyses show a larger FOV with increased distortion in prototype over production mirrors, with no difference in accurately measuring distances. Recommendations are presented for next steps of mirror development, a follow-up controlled test on the Virginia Smart Road, and field operational testing with fleets using these prototype mirrors.
