Abstract:
This document describes the Concept of Operations and Generic System Requirements for

the next generation of Traffic Management Centers (TMC). Four major steps comprise the

development of this Concept of Operations. The first step was to survey the state-of-the practice to develop a thorough understanding of how traffic networks are currently

managed. This review was conducted through interviews with TMC managers, TMC

inspection visits, and a literature search and review. The results of this review are

documented in a previous report entitled, “Traffic Management Centers - The State-of-the-

Practice”. Using the review’s results as a foundation, the second step was to develop a

comprehensive list of ATMS functions that would meet the objectives of the Intelligent

Vehicle Highway System (IVHS). This list was then used to derive ATMS functional

requirements. The functional requirements encompass the generic system requirements,

which are higher level requirements identifying critical areas where support systems are

essential for effective management and operation of ATMS. The functional requirements

served as the baseline for a top-down analysis, the third step, in which each function was

analyzed to determine requirements for the information to be input, the necessary

processing, and the output information to be produced. Using this list, more detailed

analyses were performed to identify ATMS boundaries, the role and assets of ATMS itself,

identification of external entities, data and information exchange between ATMS and

external entities, and the decomposition of functions within ATMS. A by-product of these

analyses, was the identification of ATMS subsystems and support systems and their

interrelationships. Finally, the last step was to develop a set of operational scenarios to

exercise each of the identified functions in the subsystems. The result of these analyses

provides a framework for the design of ATMS support systems.
