The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

Note that this transaction set diagram (TSD) is only 1 of the 2 TSDs and so only a portion of the numbered items below refer to the above TSD.

  1. The entire process is under the asynchronous monitoring (ISP operations information presentation) and control (ISP operator inputs) by the ISP Operator.

  2. Concurrently and asynchronously, information is collected by the ISP from a variety of sources:

    • Traffic Management Subsystem (road network conditions and incident information)

    • Transit Management Subsystem (transit and fare schedules), which includes static fare and schedule information, transit schedule adherence information, which includes real-time schedule performance information, and transit incident information, which includes real time incident information

    • Emergency Management Subsystem (incident information), including incidents arising from large-scale natural or human-caused disasters

    • Emissions Management Subsystem (air quality information)

    • Maintenance and Construction Management Subsystem (current asset restrictions), (maint and constr work plans), (roadway maintenance status), and (work zone information)

    • Parking Management Subsystem (parking information)

    • Toll Administration (toll data)

    • Border Inspection Systems (border crossing status information)

    • Event Promoters (event information)

    • Media (external reports), which include traffic or incident information collected by the media

    • Surface Transportation Weather Service (transportation weather information)

    • Weather Service (qualified environmental conditions data and weather information)

    • Other (ISP coordination), which provides for multiple ISPs exchanging information from separate sources for purposes of augmenting the broadcast information or corroborating specific information items

    This information is often based upon exceptional conditions, such as an incident in traffic, a storm, or other special events.

    Information collected by the ISP from some sources may come as the result of a specific request or be obtained through subscriptions. Specific requests include (parking lot data request), (toll data request), (event information request), and (transportation weather information request). With subscriptions, providers usually send periodic updates on a scheduled basis.

  3. ISPs broadcast information that contains link travel times, incidents, advisories, transit services and a myriad of other traveler information. The (broadcast traveler information) is provided via the Personal Information Access Subsystem (e.g. a personal computing device) and the Remote Traveler Support Subsystem (e.g. a kiosk) for Travelers and via the Vehicle Subsystem for Drivers. Travelers may make some selections (traveler inputs) about which part of the broadcast information they view. Similarly, Drivers can select which radio channels or telematics data channels they want via (driver inputs). Drivers are then provided (driver updates) and Travelers are provided (traveler interface updates). Similar information is sent to the Media (traveler information for media). Either raw data, processed data, or some combination of both may be provided by this architecture flow.
