This ITS Architecture is a roadmap for transportation systems integration in a defined region. The architecture was developed through a cooperative effort by the region's transportation agencies and represents a shared vision of how each agency's systems will work together in the future, sharing information and resources to provide a safer, more efficient, and more effective transportation system for travelers in the region. This 2019 Update was completed with input from stakeholders throughout the state and uses the latest versions of ARC–IT Version 8.2.75. The architecture provides an overarching framework that spans all of the region's transportation organizations and individual transportation projects.
The Nevada Department of Transportation originally developed a Northern Regional Intelligent Transportation Systems (ITS) Architecture in 2004 and Southern Regional ITS Architecture in 2005. The original ITS Architectures were updated in 2007, 2013, and 2015 to reflect the changes in the National ITS Architecture (NIA) at the time and the updated ITS infrastructure, systems, and functions in the state that warranted an updated Architecture. Since 2015, the ITS infrastructure and communication has changed between agencies, travelers, and statewide functions. This 2019 Update to the ITS Architectures provides a comprehensive documentation of the existing and future plans for the ITS infrastructure, systems and agency responsibilities for ITS functionality within the state. The Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) Final Rule 23 CFR 940 (Rule 940) requires that ITS projects, for highways/streets as well as transit, conform to the Rule 940 to be able to receive federal funding.
The Southern Nevada ITS Architecture (SNVArch) region is represented in population and transportation–related activity by the Las Vegas Metropolitan area. The southern region includes the local cities which own ITS infrastructure on arterial roadways and the RTC Freeway Arterial System of Transportation (FAST) system which owns and operates ITS infrastructure on highways and freeways and also operates the arterial network infrastructure within the region from the FAST Traffic Management Center (TMC). FAST is designed to monitor and control traffic. The traffic control component of the system consists of freeway and arterial management. Traffic control requires detection of traffic conditions through the use of video image detection and inductive loop detection. Visual verification of conditions is possible through closed–circuit television cameras. Traffic control is achieved through the use of traffic signals, ramp meters, dynamic message signs, and lane use control signals. FAST is a partnership of 5 major local stakeholders in addition to NDOT. RTC and NDOT pay for the primary costs of operation of FAST. The RTC of Southern Nevada and its RTC FAST TMC, the City of Henderson, the City of North Las Vegas, the City of Las Vegas, the City of Mesquite, Boulder City and Clark County are the primary jurisdictions reflected in the 2019 Southern Nevada Regional ITS Architecture.
