The present Manual on Uniform Traffic Control Devices (MUTCD) contains no minimum, initial or maintained retroreflective requirements for retroreflective traffic signs, pavement markings, or other traffic control devices. Faced with this situation, the Center for Auto Safety (CAS) duly petitioned the Federal Highway Administration to open rule-making on standards for retroreflective illumination. The petition makes four assertions which the CAS feels would make night driving easier and safer. These assertions relate to performance criteria for nighttime conspicuity, maintained illumination levels, retroreflective materials for illuminating signs and road markings, colors and their intensity in signs, standards for brightness and color. The petition comments on the basic parameters of driver behavior, particularly response time, and the need for a more realistic design driver. The questions proposed by FHWA relating to retroreflective standards in response to the petition are set-forth. Comments made on FHWA Docket 85-18 "Standards for Performance of Retroreflective Standards" are analyzed.
