I don't believe that the detectable warnings requirement is at all tied to who is in charge of the legislature. The suspension in 1992 was related to concerns about the requirement of the DW on the full width and depth of the ramp and to allow some additional research. That research was done and the recommendation is that the requirement be changed to require that the DW be installed only on the lower 24 inches of the ramp rather than installing it on the entire width and depth of the ramp. National Federation of the Blind and American Council of the Blind are now in agreement on the use of detectable warnings on ramps where the slope is lower than 1:15; the only disagreement is that NFB says DW is not really needed if the ramp slope is between 1:12 and 1:15. But the Draft Public Rights of Way Guidelines require DW on all ramps and level transitions to street crossings, etc. The requirement should certainly not be suspended; blind pedestrians walked into the street on 50% of approaches on curb ramps without DW and with a lower slope than 1:12. Not exactly at desirable choice, in my opinion; just install the detectable warnings.
