Architecture Scope
The scope of the Regional ITS Architecture can be described in terms of: 1) the size of the region and jurisdictions covered (geographic scope), 2) the planning or time horizon, and 3) the variety of transportation services that are covered. This scope is defined in the context of adjacent and overlapping Regional ITS Architectures.
Description
This is the regional ITS architecture for the North Carolina Triangle Region. The architecture is sponsored by the Triangle ITS Communications Partners, representing the Durham–Chapel Hill–Carrboro Metropolitan Planning Organization (DCHC MPO), the Capital Area Metropolitan Planning Organization (CAMPO), the North Carolina Department of Transportation (NCDOT), the Federal Highways Administration (FHWA) and local governments within the region. Because no North Carolina Statewide ITS Architecture existed at the time when this version was developed, this architecture also includes some services and elements that would normally belong in a statewide ITS architecture, including Electronic Toll Collection and the NCDOT State Traffic Operations Center (STOC).
Note on the Timeframe: The timeframe for the main focus of the architecture is on items to be implemented in the next 10 years. DCHC and CAMPO update the Metropolitan Transportation Plan every 4 years with a 25–year horizon. Looking at the 10–year to 25–year range there are some longer–term initiatives like Automated Vehicle and Integrated Corridor Management that will be included in the architecture to support longer range planning.
Time Frame
10 years (see note in the Description above)
Geographic Scope
The Triangle Regional ITS Architecture includes Orange, Durham, and Wake Counties and portions of Chatham, Franklin, Granville, Harnett, Johnston, Vance, and Warren Counties. This area includes all of the geographic area covered by the DCHC MPO and CAMPO. From NCDOT's perspective this region covers mostly Division 5 with portions of Division 7 to the west, Division 8 to the southwest, Division 6 to the south, and Division 4 to the southeast.
Service Scope
The Triangle Regional ITS Architecture includes the following functional areas: Traffic, Transit, Data Management, Traveler Information, Commercial Vehicle (HAZMAT response only), Emergency Management / Public Safety, as well as Weather Data and Maintenance & Construction Management. NCDOT Highway Divisions 4, 5, and 6 also manage additional local signal systems beyond the regional boundaries and may be involved in integrating those systems into a larger statewide communications network. There are also some commute sheds outside the regional boundaries where drivers/travelers may be coming into the Triangle region and participating in some of the services shown in this architecture.
