Interface: Commercial Vehicles - County and City Connected Vehicle Roadside Equipment
Architecture Flow Definitions
automated vehicle control parameters (Planned) Applicable ITS Standards
Information, instructions, and control parameters for automated vehicle operations including current system conditions and advisories, control parameters (e.g., speed, required vehicle performance profiles, gaps or headways) and check in/checkout instructions.
automated vehicle control status (Planned) Applicable ITS Standards
Data provided by a connected vehicle identifying it's current mode and operational status and information provided to support check–in/checkout of the lane and coordinated maneuvers while on the automated facility.
intersection geometry (Planned) Applicable ITS Standards
The physical geometry of an intersection covering the location and width of each approaching lane, egress lane, and valid paths between approaches and egresses. This flow also defines the location of stop lines, cross walks, specific traffic law restrictions for the intersection (e.g., turning movement restrictions), and other elements that support calculation of a safe and legal vehicle path through the intersection.
intersection status (Planned) Applicable ITS Standards
Current signal phase and timing information for all lanes at a signalized intersection. This flow identifies active lanes and lanes that are being stopped and specifies the length of time that the current state will persist for each lane. It also identifies signal priority and preemption status and pedestrian crossing status information where applicable.
ITS information (Planned)
Information exchanged by ITS systems or devices. This flow is a super–flow; it does not define specific content since it represents any information flow exchange between physical objects defined in ARC–IT. This information flow represents any of those information flows and inherits the data content and attributes defined in the more detailed information flows.
loading zone parking information (Planned) Applicable ITS Standards
Information provided for a loading zone and associated holding areas. It includes parking reservation(s), confirmation (or non–confirmation) information, alternative options, and detailed information on the holding parking areas, and the loading zone, including guidance within and between the holding and loading zone areas.
loading zone use request (Planned) Applicable ITS Standards
Request, booking, and confirmation that supports reservation for use of a loading or unloading area.
local signal priority request (Planned) Applicable ITS Standards
Request from a vehicle to a signalized intersection for priority at that intersection. This flow also allows the vehicle to cancel a priority request (for example, when the vehicle clears the intersection).
local traveler information (Planned) Applicable ITS Standards
Traveler information including traffic, road, and weather conditions for a particular locality. This flow includes the location–specific traveler information and time effectivity of the information.
location correction (Planned) Applicable ITS Standards
Information provided to improve positional accuracy. These corrections allow a mobile GPS receiver, such as a GPS system in a connected vehicle, to achieve a
greater absolute positional accuracy, compensating for errors that exist in satellite positioning.
map updates (Planned) Applicable ITS Standards
Map update which could include a new underlying static or real–time map or map layer(s) update.
parking availability (Planned) Applicable ITS Standards
Information on available parking. This flow identifies available spaces with associated information about parking restrictions and location for each available space.
parking facility geometry (Planned) Applicable ITS Standards
Precise spatial description of a parking facility that locates each parking space and the ingress and egress routes that are used to travel to and from the spaces.
roadway geometry (Planned) Applicable ITS Standards
The physical geometry of a road segment that specifies the location and width of each lane, including normal lanes as well as special lanes for pedestrians and bicycles, transit vehicles, and trains. This flow also may include the curvature, grade, and superelevation or banking of the road segment.
service advertisement (Planned) Applicable ITS Standards
An advertisement of available services and identification of how those services may be accessed (e.g., RF parameters, identifiers, etc.). Services include network services such as IPv6 routing, public roadside services such as intersection safety, back office services including situation data services and security credentials, or private services.
signal priority status (Planned) Applicable ITS Standards
In response to a request for signal priority, this flow indicates the status of the priority or preemption request.
vehicle environmental data (Planned) Applicable ITS Standards
Data from vehicle safety and convenience systems that can be used to estimate environmental and infrastructure conditions, including measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti–lock brake status, vertical acceleration and other collected vehicle system status and sensor information. The collected data is reported along with the location, heading, and time that the data was collected. Both current data and snapshots of recent events (e.g., traction control or anti–lock brake system activations) may be reported.
vehicle location and motion (Planned) Applicable ITS Standards
Data describing the vehicle's position, heading, speed, acceleration, transmission, steering wheel angle, braking status, size information, and trajectory.
vehicle location and motion for surveillance (Planned) Applicable ITS Standards
Data describing the vehicle's position, heading, speed, acceleration, transmission, steering wheel angle, braking status, size information, and trajectory. This flow represents monitoring of basic safety data ('vehicle location and motion') broadcast by passing connected vehicles for use in vehicle detection and traffic monitoring applications.
vehicle payment information (Planned) Applicable ITS Standards
Information provided for payment of tolls, parking, and other transportation fees including identification that can be used to identify the payment account or source and related vehicle and service information that are used to determine the type and price of service requested. The information exchange normally supports an account debit to pay fees, but an account credit may be initiated where pricing strategies include incentives.
vehicle payment request (Planned) Applicable ITS Standards
Request for information supporting payments. For fee structures that include incentives, the request may support either an account debit or an account credit or reimbursement.
vehicle payment update (Planned) Applicable ITS Standards
Data written to vehicle equipment to support electronic toll collection or parking payment.
vehicle platoon coordination (Planned) Applicable ITS Standards
Coordination of control commands between leader and follower vehicles allowing vehicles to join, coordinate with, and separate from platoons of cooperative vehicles. This flow shares platoon size, location, and performance parameters (e.g., platoon speed and spacing) between platooned vehicles. It also coordinates maneuvers between platooned vehicles, including maneuvers as vehicles join and leave the platoon.
vehicle profile (Planned) Applicable ITS Standards
Information about a vehicle such as vehicle make and model, fuel type, engine type, size and weight, vehicle performance and level of control automation, average emissions, average fuel consumption, passenger occupancy, or other data that can be used to classify vehicle eligibility for access to specific lanes, road segments, or regions or participation in cooperative vehicle control applications.
vehicle signage data (Planned) Applicable ITS Standards
In–vehicle signing data that augments regulatory, warning, and informational road signs and signals. The information provided would include static sign information (e.g., stop, curve warning, guide signs, service signs, and directional signs) and dynamic information (e.g., current signal states, grade crossing information, local traffic and road conditions, detours, advisories, and warnings).
