Architecture Flow Definitions
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
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.
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.
traffic images (Planned)
High fidelity, real-time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications.
