• Abstract:
  South Florida drivers have become used to the presence of managed lanes on I-95. This program, called I-95 Express, reserves the leftmost lanes for drivers willing to pay a toll that varies with traffic volumes. Managed lanes reduce congestion by moving drivers who are traveling to more distant exits from drivers planning to exit the highway sooner. I-95 Express lanes are separated from general traffic lanes by delineators. These devices take a fair amount of abuse, by being run over or being bumped. They are easy to replace, but a more robust delineator could greatly reduce replacement and crew costs and improve safety by reducing the exposure of crews to the hazards of roadway work.
