CARTESIUS Distributed Congestion Manager

• A knowledge-based real-time, distributed operator
  decision support system for congested
  environments
  
• One agent (Caltrans D12) is responsible for the
  freeway network, and a second agent (Irvine
  ITRAC) is responsible for the arterial network
  (additional agents may represent public transit
  agencies, law enforcement, etc.)
• Incorporates and/or coordinates with (a) incident
  detection algorithms, (b) traffic signal and ramp
  control algorithms, and (c) CMS and other ATIS
  operations
