  1. BRINGING ACS-LITE TOYOUR AGENCY John Thai, P.E. City of Anaheim September 8, 2011

  2. ACS-Lite Project Area • TOY STORY LOT • Additional 2678 new spaces to • existing 1000 spaces • Shuttle buses to Disneyland • Accommodate varying tourist conditions • Accommodate varying park hours • Total parking to be 29,000 spaces • WWJD • Install adaptive traffic control solution • Upgrade infrastructure to fiber • Upgrade controllers • Add CCTV surveillance

  3. What Adaptive Isn’t… • Panacea to traffic congestion • Turn it on and forget about it • Maintenance-free type of operation • Means to reduce head count

  4. Why Adaptive Traffic Control? • Optimization of signal timing • Retiming • Optimize phase splits • Provide progression • Time based coordination • Interconnect traffic signals • Central traffic management • Optimize offsets • Dynamically fine-tune optimized signal timing plans

  5. Adaptive Control in Action

  6. Adaptive Control in Action

  7. Adaptive Control in Action

  8. Why ACS-Lite?

  9. Why ACS-Lite? • Leverage existing infrastructure • Retrofit with existing controllers • Utilize existing fully actuated detector layout • Utilize existing communication infrastructure • Provide improvements over typical TOD timing • Dynamically compensate for variations in traffic • Operate with existing traffic controllers • Use NTCIP protocol • Lower deployment costs than other Adaptive Systems

  10. Why ACS-Lite? Day-by-Day Cycle-by-Cycle Second-by-Second

  11. Available ACS-Lite Configurations ACS-Lite to controllers via NTCIP ACS-Lite to controllers via NTCIP + Econolite protocol ACS-Lite to FM via NTCIP, then Bi Tran protocol to controllers ACS-Lite to Translators via NTCIP, then Peek protocol to controllers

  12. Anaheim’s ACS-Lite Vision CENTRAL SYSTEM + ACS-LITE MODULE

  13. Designing for ACS-Lite • Systems Engineering “Lite” • Communications infrastructure review • Upgraded to Ethernet over fiber in mid-2011 • Stopbar and advanced detection review • What is the optimal detector configuration? • Can we use what we already have? • Infrastructure review • Conduit fill • Pullboxes • Comm. vault • Comm. hub

  14. Design Example Phase Utilization Flow Profile

  15. Configuring ACS-Lite

  16. Configuring ACS-Lite

  17. ACS-Lite Real-Time Data

  18. ACS-Lite Real-Time DataPhase Timing

  19. ACS-Lite Real-Time DataPhase Utilization

  20. ACS-Lite Real-Time DataFlow Profile

  21. ACS-Lite Real-Time DataDetectors

  22. ACS-Lite Evaluation Needed!!! 6 2 5 4 3 1

  23. Now bring ACS-Lite to your agency… • Systems Engineering “Lite” is necessary • A series of simple steps to review deployment strategy • One-time vs. incremental system-wide deployment? • What is required of deployment? • How ready is your infrastructure? • How will you pay for on-going operations and maintenance? • It’s best to find out now • Agency commitment to on-going operations and maintenance is vital • Are decision makers fully on-board? • Is maintenance staff fully on-board? • Performance measures automation • Establish clear and tangible measures • Find out what works and what doesn’t • Improve on what we do well • Share lessons learned • Marketing will foster public understanding and support
