Architecture Flow Definitions
emergency transit schedule information (Planned)
Information on transit schedule and service changes that adapt the service to better meet needs of responders and the general public in an emergency situation, including special service schedules supporting evacuation.
incident information (Planned)
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.
request transit information (Planned)
Request for transit service information and current transit status.
road network conditions (Planned)
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.
traffic control priority request (Planned)
Request for signal priority at one or more intersections along a particular route.
traffic control priority status (Planned)
Status of signal priority request functions at the roadside (e.g. enabled or disabled).
traffic images (Planned)
High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.
transit demand management request (Planned)
Request to change the demand for transit facility use through pricing or other mechanisms.
transit demand management response (Planned)
Response to transit demand management change requests indicating level of compliance with request.
transit probe data (Planned)
Aggregate probe data derived from tracking transit vehicles. Data collected could include transit vehicle speeds and travel times for a given link or collection of links.
transit system data (Planned)
Current transit system operations information indicating current transit routes, the level of service on each route, and the progress of individual vehicles along their routes for use in forecasting demand and estimating current transportation network performance.
