VDOT Statewide and District ITS Architectures
ITS User Services describe what functions ITS perform from the user's perspective. The National ITS Architecture defines Service Packages that "bundle" multiple ITS Elements to address specific transportation management services, such as surface street control or traveler information.
An ITS Service Package is not in and of itself, an ITS project. Instead, Service Packages are the "building blocks" of ITS, and a specific ITS project may include multiple Service Packages that provide multiple interrelated functions. For example, a transit ITS project designed to improve service efficiency may include Service Packages for vehicle tracking, fixed-route schedule management, and automated passenger counting.
Stakeholders can use services to better understand the integration necessary to address transportation needs. Selecting a service from the list on the Services tab provides a description of the service and a list of the elements involved in the service for its delivery in the context of the SITSA. A service diagram provides a complete view of the service. Stakeholders exploring the services can find the services meeting their needs for future project definition. Additional services can be defined using the Regional Architecture Development for Intelligent Transportation (RAD-IT) and those services can be integrated into the SITSA during a future maintenance update. When defining a project, a stakeholder should use the services in the SITSA or a new service defined with the RAD-IT software to define the services a project will deliver to meet specific needs.
Service Packages specific to each VDOT ITS project are listed on the ITS Project pages.
The following is a list of the Service Packages defined in the Statewide Architecture Regional ITS Architecture (SITSA), including Service Package "instances" that are versions of Service Packages specific to an ITS project or stakeholder.
