Inputs/Outputs: Architecture Flows* and Data Flows*

Emergency Management Media

• incident information for media (Architecture Flow*) - Report of current desensitized incident information prepared for public dissemination through the media.
  Data Flows*:
  • tm-emergency_information

Emissions Management Media

• air quality information (Architecture Flow*) - Aggregated region-wide measured air quality data and possible pollution incident information.
  Data Flows*:
  • tm-pollution_data

Information Service Provider Media

• traveler information for media (Architecture Flow*) - General traveler information regarding incidents, unusual traffic conditions, transit issues, or other advisory information that has been desensitized and provided to the media.
  Data Flows*:
  • tm-incident_information
  • tm-traffic_information
  • tm-transit_vehicle_deviations
  • tm-traveler_information_request

Maintenance and Construction Management Media

• maint and constr work plans (Architecture Flow*) - Future construction and maintenance work schedules and activities including anticipated closures with anticipated impact to the roadway, alternate routes, anticipated delays, closure times, and durations.
  Data Flows*:
  • tm-m_and_c_work_plans_for_media

• road weather information (Architecture Flow*) - Road conditions and weather information that are made available by road maintenance operations to other transportation system operators.
  Data Flows*:
  • tm-road_weather_info

• roadway maintenance status (Architecture Flow*) - Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).
  Data Flows*:
  • tm-roadway_maint_status_for_media

• work zone information (Architecture Flow*) - Summary of maintenance and construction work zone activities affecting the road network including the nature of the maintenance or construction activity, location, impact to the roadway, expected time(s) and duration of impact, anticipated delays, alternate routes, and suggested speed limits. This information may be augmented with images that provide a visual indication of current work zone status and traffic impacts.
  Data Flows*:
  • tm-work_zone_images
  • tm-work_zone_info

Media Information Service Provider

• external reports (Architecture Flow*) - Traffic and incident information that is collected by the media through a variety of mechanisms (e.g., radio station call-in programs, air surveillance).
  Data Flows*:
  • fm-incident_details
  • fm-traveler_information

Media Traffic Management

• external reports (Architecture Flow*) - Traffic and incident information that is collected by the media through a variety of mechanisms (e.g., radio station call-in programs, air surveillance).
  Data Flows*:
  • fm-incident_information

Traffic Management Media

• incident information for media (Architecture Flow*) - Report of current desensitized incident information prepared for public dissemination through the media.
  Data Flows*:
  • tm-incident_data

• road network conditions (Architecture Flow*) - Current and forecasted traffic information, road and weather conditions, and other road network status. Either raw data, processed data, or some combination of both may be provided by this architecture flow. Information on diversions and alternate routes, closures, and special traffic restrictions (lane/shoulder use, weight restrictions, width restrictions, HOV requirements) in effect is included along with a definition of the links, nodes, and routes that make up the road network.
  Data Flows*:
  • tm-traffic_data

Transit Management Media

• transit incidents for media (Architecture Flow*) - Report of an incident impacting transit operations for public dissemination through the media.
  Data Flows*:
  • tm-transit_emergency_information
  • tm-transit_incident_information

• transit information for media (Architecture Flow*) - Report of transit schedule deviations for public dissemination through the media.
  Data Flows*:
  • tm-transit_schedule_deviations_to_media
