Designing an Efficient Nighttime Sign Inspection Procedure to Ensure Motorist Safety 
The major objective of this study is to provide a road sign replacement simulation that NCDOT can use to optimize the management of signs. To create the simulation, the research team modeled the performance of NCDOT sign inspectors, determined sign retroreflectivity performance with age, and
determined external factors that affect sign performance. Research assistants accompanied NCDOT sign crews during nighttime sign inspections. During these inspections, signs needing replacement were identified and noted by the research team. NCDOT, September 2006.
