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
