This multi-year project focuses on integrating Caltrans primary signal management system, CTNET, with a major product from the Caltrans ATMS Testbed: the Coordinated Adaptive Real-Time Expert System for Incident management in Urban Systems, or more simply, CARTESIUS . The research will focus on delivering numerous software products for integrating CTNET with field devices, simulation software, with other traffic management systems in general, and with a streamlined re-implementation of the CARTESIUS incident management system. The system will require various software components necessary for external systems with CTNET using both the AB3418e protocol and CTNET’s own custom socket-based communications protocol for communications between CTNET clients and the CTNET CommServer. The use of these software components will link CTNET to various systems including a non-standard field infrastructure, the Paramics microsimulation, and the CARTESIUS incident management system. The resulting system will be used to evaluate a more deployable re-implementation of CARTESIUS connected to the simulation via CTNET.
