• Abstract:
  Roadway lighting is provided on selected highways to improve the visibility of the nighttime environment.
  
  Roadway lighting is typically warranted on the basis of the daily traffic volume. However, in the earlymorning
  
  hours, the traffic volumes may be so low as to diminish the need for roadway lighting. At present,
  
  the lighting infrastructure in place on Texas Department of Transportation (TxDOT) highways is not well
  
  suited to being dimmed. As a result, turning off roadway lighting during early morning hours is the only
  
  option. This concept is known as a lighting curfew for purposes of this research project. The lighting curfew
  
  section of the TxDOT 2003 Illumination Manual does not provide specific guidelines or criteria for
  
  implementing lighting curfews. Although lighting curfews are of interest around the country, no state has
  
  developed guidelines for lighting curfews, nor are there national guidelines at this time. The most significant
  
  potential benefits of lighting curfews include reduced power consumption and reduced light pollution.
  
  This project focused upon developing guidelines for implementing lighting curfews on urban freeways,
  
  which have the potential to impact TxDOT’s ability to manage its lighting infrastructure in an advantageous
  
  manner. The guidelines developed through this project identify threshold criteria under which freeway main
  
  lane lighting can be turned off. The guidelines also identify conditions or exceptions under which lighting
  
  curfews should be suspended, modified, canceled, or not used at all (such as periods of inclement weather or
  
  during a major late-night event).
