• Abstract:
  The Manual on Uniform Traffic Control Devices (MUTCD) has developed minimum retroreflectivity requirements for sign sheeting that will ; become a federal mandate for roadside signs in 2015 and for overhead signs in 2018. In 2012, the New Hampshire Department of ; Transportation (NHDOT) was required by the Federal Highway Administration (FHWA) to have a plan in place for meeting these requirements. ; The MUTCD has identified five acceptable methods that fall into two categories for determining if signs meet the requirements. In the ; Assessment category, the methods listed are Visual Nighttime Inspection and Measured Sign Retroreflectivity. In the Management category, the ; methods listed are Expected Sign Life, Blanket Replacement, and Control Signs. ; This project focused on determining a method that was most suited to the needs of the NHDOT. Each method has advantages and ; disadvantages that were considered during the selection of an appropriate plan. ; Once all the methods were assessed, it was determined that Visual Nighttime Inspection would be the most economical due to the quickness that ; the review can be accomplished and the minimal resources required to conduct the inspection. Another major factor for selecting the visual ; night inspection was that a statewide sign inventory is currently not available. If a current inventory was available, other methods may prove to ; be more efficient.
