Architecture Flow Definitions

device data  (Planned)  Applicable ITS Standards

Data from detectors, environmental sensor stations, roadside equipment, 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.

maint and constr resource request  (Planned)  Applicable ITS Standards

Request for road maintenance and construction resources that can be used in the diversion of traffic (cones, portable signs), clearance of a road hazard, repair of ancillary damage, or any other incident response. The request may poll for resource availability or request pre–staging, staging, or immediate dispatch of resources.

maint and constr resource response  (Planned)  Applicable ITS Standards

Current status of maintenance and construction resources including availability and deployment status. General resource inventory information covering vehicles, equipment, materials, and people and specific resource deployment status may be included.

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 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.

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.

traffic images  (Planned)  Applicable ITS Standards

High fidelity, real–time traffic images suitable for surveillance monitoring by the operator or for use in machine vision applications. This flow includes the images and meta data that describes the images.
