Lesson Learned

From their investigations, the authors had a list of recommendations for agencies choosing to implement RLC systems:
  • Agencies should follow the development guidelines published by FHWA, only using RLCs as a "last resort."
  • Agencies should develop effective deployment guidelines to account for behavioral discrepancies among driving populations and locality-specific constraints.
  • Agencies should perform observations of vehicle approaching speeds at candidate-RLC intersections, in particular noting the percentage of aggressive drivers.
  • Agencies should implement safety strategies at intersections with high percentages of aggressive drivers in order to increase the probability of a successful RLC deployment.
  • Agencies should perform extensive field observations at both RLC and non-RLC intersections to develop guidelines and design control strategies.
