34CARTESIUS 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
