Fluorescent Yellow-Green Signs

In the Manual on Uniform Traffic Control Devices (MUTCD), fluorescent yellow-green (FYG) is the required color used for school signs and can be used as an option for bicycle and pedestrian (B/P) crossing signs. Due to the uniqueness of appearance, MoDOT currently reserves the FYG primarily for school signs. The only time MoDOT uses FYG for B/P crossing signs is if a state route and a city route crossed and the city used FYG at that location. MoDOT has been encouraged to change current pedestrian crossing signs from Fluorescent Yellow (FY) to FYG. This is based in the perception that FYG is safer than FY. However, MoDOT has a large inventory of FY signs on the state system with each sign lasting at least 15 years and would not consider switching to FYG signs in part (or whole) unless there is fact-based evidence that the color change would provide a significant safety benefit due to fiscal and logistical impacts. MoDOT is interested in discovering other state DOT policies and research regarding the use of FYG in pedestrian crossing signs. The department wants to know if current research indicates any significant safety impact to bicyclists and pedestrians if FYG signs are used instead of FY.
