Information Flow Definitions

alternate mode information (Existing)

Schedule information for alternate mode transportation providers such as air, ferry, and passenger-carrying heavy rail. This also includes details of incidents and other service disruptions that have occurred in the alternative mode. This also includes measures of service demand that supports assessment of their impact on the road network.

data provision (Existing)

Data provision provides the source material for a publish-subscribe or query-retrieval data distribution scheme. This is the 1 of the 1:N data distribution architecture. This flow is a super-flow; it does not define data elements but is inclusive of any flow implemented using publish-subscribe or query-retrieval methods.

emergency traveler information request (Existing)

Request for alerts, evacuation information, and other emergency information provided to the traveling public.

incident information (Existing)

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.

parking information (Existing)

General parking information and status, including current parking availability, parking pricing, and parking space availability information.

road network conditions (Existing)

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 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.

transit and fare schedules (Planned)

Transit service information including routes, schedules, and fare information. This also includes on-demand service information.

transit incident information (Planned)

Information on transit incidents that impact transit services for public dissemination.

transit schedule adherence information (Planned)

Dynamic transit schedule adherence and transit vehicle location information.
