Information Flow Definitions

device control request  (Existing)  Selected Comm Solution

Request for device control action

device data  (Existing)  Selected Comm Solution

Data from detectors, environmental sensor stations, roadside equipment, and traffic control devices, including device inventory information.

device identification  (Planned)  

An identifier and device type designation that is used to uniquely identify a device in the Connected Vehicle Environment.

device status  (Existing)  Selected Comm Solution

Status information from devices

emergency traffic coordination  (Existing)  Selected Comm Solution

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.

incident information  (Existing)  Selected Comm Solution

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.

permission application  (Planned)  

A request for permission to access a Connected Vehicle service by an end–user that requires enrollment. This may include services granted to drivers of low emissions vehicles or pedestrians with special needs that require extended crossing times for example.

permission application receipt  (Planned)  

An acknowledgment that an end–user application for a Connected Vehicle service was received and processed.

road network conditions  (Existing)  Selected Comm Solution

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.

traffic image meta data  (Existing)  

Meta data that describes traffic images. Traffic images (video) are in another flow.

traffic images  (Existing)  

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. Meta data that describes the images is contained in another flow.

transportation operational strategies  (Existing)  

Operational strategies for each operating agency in a transportation corridor, downtown area, or other travel–impacted area, providing an integrated operations strategy for the freeways, tollways, arterials, transit services, parking facilities, and other transportation–related facilities in the area. These strategies can include dynamic adjustments to transit fares and tolls, parking fees and restrictions, dynamic lane restriction changes, and other active demand management strategies.
