• Abstract:
  The purpose of the current study was to further develop and refine the prototype Enhanced Rear Signaling (ERS) ; system that was developed during the previous Phase III effort. Expanded development efforts for the ERS system ; included modification of the system into a unit designed for simple commercial motor vehicle (CMV) installation, ; collision-warning activation refinements, and rear lighting brightness adjustments for nighttime conditions. During ; the ERS system development process, the team successfully completed necessary modifications for improved CMV ; installation. Formal closed test-track and real-world testing were then performed to determine the ERS system ; collision-warning activation performance. Ultimately, the ERS system performed with a 100 percent correct ; detection rate and an 85.43 percent correct rejection rate during real-world testing. During all ERS system ; activations, no unsafe following vehicle driver reactions/behaviors were observed, indicating a promising system for ; follow-on research. A nighttime brightness level was selected at the conclusion of a ratings study and carried on into ; nighttime real-world testing. During ERS system nighttime activations, there were also no unsafe following-vehicle ; driver reactions/behaviors observed. Overall, the research team found that the ERS system is ready for further ; evaluation in a field operational test (FOT).
