The Testbed Real-time Integrated Control and Evaluation Prototype System (TRICEPS) was developed in prior Partners for Advanced Transit and Highways (PATH) research as an implementation platform to provide “plug and play” capabilities for the testing and evaluation of a range ATMIS modules (McNally et al., 2002). TRICEPS permits modules to be configured for various Advanced Transportation Management and Information System (ATMIS) applications and run in simulated, real-time, and integrated modes. One of the key modules implemented for use with Testbed Real-time Integrated Control and Evaluation Prototype System (TRICEPS) is the real-time multi-agent incident management system Coordinated Adaptive Real-Time Expert System for Incident management in Urban Systems (CARTESIUS). Traffic management in urban corridors is complicated by jurisdictional as well as operational problems. Corridor traffic demand increasingly require coordinated management that optimizes corridor traffic while preserving the various levels of authority, data control, and decision-making power. CARTESIUS approaches this problem by employing advanced cooperation and conflict resolution methodologies for coordinated traffic management operations among multiple agents. In this Testbed project, TRICEPS/CARTESIUS will be field tested in two evaluation modes. In the first mode, the system will process real-time data coming from sensors in the field and will provide advisory management strategies and control actions for the consideration of California Department of Transportation (Caltrans), District 12–Orange County (Caltrans–D12) and City of Irvine Traffic Management Center (ITRAC) personnel. The second evaluation mode will involve usability and stress testing of the TRICEPS/CARTESIUS system with the CARTESIUS agents remotely connected to the Paradyn traffic simulator at the UCI laboratories, where Transportation Management Center (TMC) operators/personnel will be asked to respond to the scenarios using CARTESIUS to implement control strategies in Paradyn.
