Architecture Flow Definitions
alternate mode information (Existing)
Schedule information for alternate mode transportation providers such as air, ferry, and passenger–carrying heavy rail.
commercial vehicle permit information (Planned) Applicable ITS Standards
Information about commercial vehicle permits for oversize, overweight, or for dangerous goods.
current infrastructure restrictions (Existing) Applicable ITS Standards
Restrictions levied on transportation asset usage based on infrastructure design, surveys, tests, or analyses. This includes standard facility design height, width, and weight restrictions, special restrictions such as spring weight restrictions, and temporary facility restrictions that are imposed during maintenance and construction.
emergency traveler information (Existing)
Public notification of an emergency such as a natural or man–made disaster, civil emergency, or child abduction. This flow also includes evacuation information including evacuation instructions, evacuation zones, recommended evacuation times, tailored evacuation routes and destinations, traffic and road conditions along the evacuation routes, traveler services and shelter information, and reentry times and instructions.
equipment maintenance request (Planned) Applicable ITS Standards
Identification of field equipment requiring repair and known information about the associated faults.
equipment maintenance status (Planned) Applicable ITS Standards
Current status of field equipment maintenance actions.
incident information for public (Existing) Applicable ITS Standards
Report of current desensitized incident information prepared for public dissemination.
maint and constr work plans (Existing) Applicable ITS Standards
Future construction and maintenance work schedules and activities including anticipated closures with anticipated impact to the roadway, alternate routes, anticipated delays, closure times, and durations.
parking information (Existing)
General parking information and status, including current parking availability.
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.
road network environmental situation data (Existing) Applicable ITS Standards
Aggregated environmental situation data collected from vehicles and other sources for the road network. Aggregated information would include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, ALB status, and other collected vehicle system status and sensor information for the region.
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.
roadway maintenance status (Planned) Applicable ITS Standards
Summary of maintenance fleet operations affecting the road network. This includes the status of winter maintenance (snow plow schedule and current status).
route restrictions (Planned) Applicable ITS Standards
Information about routes, road segments, and areas that do not allow the transport of security sensitive hazmat cargoes or include other restrictions (such as height or weight limits).
traffic control information (Existing) Applicable ITS Standards
Represents the flow of traffic control and status information from a TMC to a third party TIC. This is reporting only, not actual control.
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 and meta data that describes the images.
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.
work zone information (Existing) Applicable ITS Standards
Summary of maintenance and construction work zone activities affecting the road network including the nature of the maintenance or construction activity, location, impact to the roadway, expected time(s) and duration of impact, anticipated delays, alternate routes, and suggested speed limits. This information may be augmented with images that provide a visual indication of current work zone status and traffic impacts.
