NCHRP 03-152 examines how state and regional transportation agencies manage the software used in their Traffic Management Systems (TMS) over its full life cycle. Modern TMS software supports core functions such as collecting and processing field data, running control algorithms, and providing decision-support and traveler-information services, and it must be planned, integrated, and maintained systematically as agencies adopt new technologies and data sources. The University of Arizona, together with Iteris, Inc. and OZ Engineering, will document current practice through a state-of-the-practice review, agency surveys, and interviews covering planning, procurement, configuration management, testing, maintenance, and upgrades. The project's main product is a guide, supported by checklists and templates, that transportation agencies can use to make consistent and well-informed decisions in managing TMS software across its life cycle.
