    • Reduced number of stops by 8.3%
    • Reduced stopped time delay by 12%
    • Traffic Volume increased by 9%
slide24

Project Benefit

  • Over the last year during AM/PM peaks:
    • Eliminated 1.2 million hours of delay
    • Saved 700,000 gallons of fuel
rtop funding
RTOP Funding
  • Late start the first year – funding cut
  • Success in 2011 and 2012 lead to increased funding
  • Program now in expansion phase
