ATIS10-Short Range Communications Traveler Information (Service Package*)

Description

This service package provides location-specific or situation-relevant information to travelers in vehicles using Dedicated Short Range Communications (DSRC) infrastructure supporting mobility applications for connected vehicles. DSRC is used to deliver real-time traveler information including travel times, incident information, road conditions, and emergency traveler information to vehicles as they pass DSRC roadside equipment along their route. This service package provides public information that is available to all equipped vehicles in the vicinity of the roadside equipment.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

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 TSD.
ATIS10 transaction set diagrams: Part 1, Part 2,



The source graphic, a Windows Metafile (WMF), for the TSDs can be downloaded here: TSD Part 1, TSD Part 2,

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.

  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, traffic images and incident information)

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

    • Emergency Management Subsystem (incident information, alert notification, evacuation information, transportation system status), 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)

    • Payment 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 (incident information, multimodal information, parking information, road network conditions, traffic images, transit service information), 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. The ISP sends traveler information (broadcast traveler information and emergency traveler information) to short range communications equipment in the Roadway Subsystem.

  4. The Roadway Subsystem uses short range communications to send the traveler information (broadcast traveler information and emergency traveler information) to passing vehicles.

  5. Vehicle equipment presents the traveler information to the driver (driver updates). The driver controls the information that is presented (driver inputs).

  6. Short range communications status is sent to the ISP, allowing remote monitoring of short range communications equipment.

  7. The ISP notifies the Maintenance and Construction Management Subsystem (MCMS) of the current operation and fault status of the short range communications equipment (field equipment status).

  8. In case of maintenance actions, equipment maintenance status is sent from the MCMS to the ISP, notifying the ISP when the operational status of short range communications equipment changes.
