In areas without an existing Intelligent Transportation System (ITS) infrastructure, ITS measures are still among the most effective in reducing delays and excess emissions associated with construction projects. The Architecture Subsystem Interconnect Diagram in the United States National Architecture Standards is an effective tool to quickly determine the packages that can be implemented prior to construction start-up and that would be cost-effective in addressing delays and the effects of construction-related incidents. This paper presents three case studies of implementation using the National ITS Architecture for construction projects that vary in size, complexity, and actual ITS elements implemented. The success and cost-effectiveness of each element is discussed. Also discussed are non-technical issues that affected the success of the implementation. Use of the Architecture Subsystem Interconnect Diagram did indeed greatly reduce planning hours and costs by enabling rapid determination of feasible elements for work zone incident management.
