CARTESIUS, a multi-agent, real-time expert system for congestion management, is linked with CTNet, software for monitoring and controling traffic signals [ Project Summary (pdf) ].

Funded by California PATH.


Overview of CARTESIUS and CTNet Integration

Non-recurrent congestion presents a difficult problem for existing localized automated traffic control systems such as the Caltrans Traffic Signal Management and Surveillance System (CTNET). These systems operate with control parameters that are fine-tuned to meet the normal demands of recurrent congestion in the system. Incidents in the system can create disturbances that are beyond the control of such localized systems, rendering them incapable of mitigating the resultant delays. This creates a compelling justificaion for interfacing the CTNET signal control subsystem with a global traffic management subsystem to develop a general corridor traffic management architecture that can dynamically respond to inidents in the system. CARTESIUS is such a tool.

The proposed research is a two year project to first integrate these CARTESIUS and CTNET projects to produce a functioning traffic management system and then evaluate the integrated system under controlled conditions in a field operational test. The research in the first year will involve extensive study of both CARTESIUS and CTNET to develop a software integration plan which will be carried out to produce a working laboratory prototype. The second year of research will involve a field operational test of CARTESIUS that uses a freeway management agent, the integrated CARTESIUS/CTNET agent, and possibly an additional municipal CARTESIUS agent.

Key Words: ATMS, CTNet, CARTESIUS, corridor traffic control, congestion management, realtime data.
