• Abstract:
  This research details a field study of LED traffic signals in Missouri and develops a replacement schedule
  
  based on key findings. Rates of degradation were statistically analyzed using Analysis of Variance
  
  (ANOVA). Results of this research will provide a methodology for engineering managers in state
  
  departments of transportation and local communities in identifying best practices and replacement standards
  
  for LED traffic signal technology.
