BRINGING ACS-LITE TOYOUR AGENCY

John Thai, P.E.

City of Anaheim

September 8, 2011

acs lite project area
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
what adaptive i sn t
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
why adaptive traffic control
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
why acs lite1
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

designing for acs lite
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

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
