Abstract: This report describes the results of PATH Task Order 5324—the first year of a multi-year project to integrate the Cartesius incident management system with Cal-trans CTNET traffic signal management system. The results of this research are a set of software requirements for reimplementing the Cartesius to interoperate with CTNET. An analysis of the existing Cartesius prototype explains how the need to focus the system on deployment and technical shortcomings of the existing system justifies a reimplementation of the software. From here, we describe the problem to be solved by the new software implementation, including general use cases, the expected users, the systems that Cartesius will interoperate with, and the constraints that will be placed on the system. The problem statement is followed by a detailed discussion of the functional requirements, database requirements, the user interface requirements, and other external interface requirements. The report concludes with a discussion the reimplementation work to be completed under PATHTask Order 6324. This reimplementation will serve the more general purpose of making Cartesius capable of working with existing traffic management subsystems to provide multi-jurisdictional incident mitigation, thus improving its deployability and subsequent value for Caltrans.
