Architecture Flow Definitions
current asset restrictions (Planned) Applicable ITS Standards
Restrictions levied on transportation asset usage based on infrastructure design, surveys, tests, or analyses. This includes standard facility design height, width, and weight restrictions, special restrictions such as spring weight restrictions, and temporary facility restrictions that are imposed during maintenance and construction.
device control request (Planned) Applicable ITS Standards
Request for device control action
device data (Planned) Applicable ITS Standards
Data from detectors, environmental sensor stations, and traffic control devices including device inventory information.
device status (Planned) Applicable ITS Standards
Status information from devices
emergency traffic coordination (Planned) Applicable ITS Standards
Coordination supporting disaster response including evacuation and reentry. Includes coordination of special traffic control strategies that support efficient evacuation and reentry while protecting and optimizing movement of response vehicles and other resources responding to the emergency.
equipment maintenance status (Planned) Applicable ITS Standards
Current status of field equipment maintenance actions.
event confirmation (Planned) Applicable ITS Standards
Confirmation that special event details have been received and processed.
event plans (Planned) Applicable ITS Standards
Plans for major events possibly impacting traffic.
external reports (Planned) Applicable ITS Standards
Traffic and incident information that is collected by the media through a variety of mechanisms (e.g., radio station call-in programs, air surveillance).
fare and price information (Planned) Applicable ITS Standards
Current transit, parking, and toll fee schedule information.
field equipment status (Planned) Applicable ITS Standards
Identification of field equipment requiring repair and known information about the associated faults.
incident information (Planned) Applicable ITS Standards
Notification of existence of incident and expected severity, location, time and nature of incident. As additional information is gathered and the incident evolves, updated incident information is provided. Incidents include any event that impacts transportation system operation ranging from routine incidents (e.g., disabled vehicle at the side of the road) through large-scale natural or human-caused disasters that involve loss of life, injuries, extensive property damage, and multi-jurisdictional response. This also includes special events, closures, and other planned events that may impact the transportation system.
logged vehicle routes (Planned) Applicable ITS Standards
Anticipated route information for guided vehicles, special vehicles (e.g., oversize vehicles) or groups of vehicles (e.g., governor's motorcade) that may require changes in traffic control strategy.
maint and constr work plans (Planned) Applicable ITS Standards
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.
map update request (Planned) Applicable ITS Standards
Request for a map update which could include a new underlying map or map layer updates.
map updates (Planned) Applicable ITS Standards
Map update which could include a new underlying static or real-time map or map layer(s) update.
railroad advisories (Planned) Applicable ITS Standards
Real-time notification of railway-related incident or advisory.
railroad schedules (Planned) Applicable ITS Standards
Train schedules, maintenance schedules, and other information from the railroad that supports forecast of HRI closures.
road network conditions (Planned) Applicable ITS Standards
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.
road network environmental probe data (Planned) Applicable ITS Standards
Aggregated vehicle probe information that can be used to estimate current environmental conditions. Collected information would include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, ALB status, and other collected vehicle system status and sensor information.
road weather information (Planned) Applicable ITS Standards
Road conditions and weather information that are made available by road maintenance operations to other transportation system operators.
roadway maintenance status (Planned) Applicable ITS Standards
Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).
route restrictions (Planned)
Information about routes, road segments, and areas that do not allow the transport of security sensitive hazmat cargoes or include other restrictions (such as height or weight limits).
traffic images (Planned)
High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.
traffic information for media (Planned) Applicable ITS Standards
Report of traffic conditions including traffic incident reports and traffic images for public dissemination through the media. The reports may also include information on diversions and alternate routes, closures, and special traffic restrictions in effect.
transportation information for operations (Planned) Applicable ITS Standards
Information on the state of transportation system operations including traffic and road conditions, advisories, incidents, transit service information, weather information, parking information, and other related data.
work plan feedback (Planned) Applicable ITS Standards
Comments and suggested changes to proposed construction and maintenance work schedules and activities. This information influences work plan schedules so that they minimize impact to other system operations and the overall transportation system.
work zone information (Planned) Applicable ITS Standards
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.
