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.

current lane restrictions  (Planned)  

Information provided to an enforcement agency that defines the current enforceable lane restrictions. It defines the location, duration, and restrictions for lanes that are reserved for the exclusive use of certain types of vehicles (e.g., transit vehicles) or vehicles that meet other qualifications (e.g., number of occupants, low emissions criteria). It identifies the lane(s), the start and stop locations, start and end times, vehicle restrictions, and speed limits.

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.

incident information for public  (Existing)  

Report of current desensitized incident information prepared for public dissemination.

incident response status  (Existing)  Selected Comm Solution

Status of the current incident response including a summary of incident status and its impact on the transportation system, traffic management strategies implemented at the site (e.g., closures, diversions, traffic signal control overrides), and current and planned response activities.

lane violation notification  (Existing)  

Notification to enforcement agency of detected lane entry violations, lane speed violations, or other dynamic lane violations. Lane entry violations may be issued for restricted vehicle types or vehicles that do not meet required emissions or passenger occupancy standards that enter a managed lane. This notification identifies the vehicle and documents the lane parameter that was violated.

parking information  (Existing)  

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

request for enforcement  (Planned)  Selected Comm Solution

Request for traffic enforcement of speed limits, lane controls, etc. on a roadway including in a work zone or other special situations.

resource deployment status  (Existing)  Selected Comm Solution

Status of resource deployment identifying the resources (vehicles, equipment, materials, and personnel) available and their current status. General resource inventory information and specific status of deployed resources may be included.

resource request  (Existing)  Selected Comm Solution

A request for resources to implement special traffic control measures, assist in clean up, verify an incident, etc. The request may poll for resource availability or request pre–staging, staging, or immediate deployment of resources. Resources may be explicitly requested or a service may be requested and the specific resource deployment may be determined by the responding agency.

road closure notification  (Future)  

Notification that agency personnel have closed a road due to adverse weather, major incident, or other reason.

road network status assessment  (Planned)  Selected Comm Solution

Assessment of damage sustained by the road network including location and extent of the damage, estimate of remaining capacity, required closures, alternate routes, necessary restrictions, and time frame for repair and recovery.

threat information  (Planned)  Selected Comm Solution

Threats regarding transportation infrastructure, facilities, or systems detected by a variety of methods (sensors, surveillance, threat analysis of advisories from outside agencies, etc.

transit service information  (Existing)  

Transit service information including routes, schedules, and fare information as well as dynamic transit schedule adherence and transit vehicle location information.

transportation system status  (Planned)  Selected Comm Solution

Current status and condition of transportation infrastructure (e.g., tunnels, bridges, interchanges, TMC offices, maintenance facilities). In case of disaster or major incident, this flow provides an assessment of damage sustained by the surface transportation system including location and extent of the damage, estimate of remaining capacity and necessary restrictions, and time frame for repair and recovery.

wrong way vehicle notification  (Future)  

Notification to public safety that a vehicle has been detected traveling in the wrong direction. It includes information about the vehicle (make, model, color, other identification data) and the current location, speed, acceleration, and heading of the wrong way vehicle.
