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 checkin/checkout of the lane and coordinated maneuvers while on the automated facility.

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 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 situation data  (Planned)  Applicable ITS Standards

This flow represents vehicle snapshots that may be provided by the vehicle to support traffic and environmental conditions monitoring. Snapshots are collected by the vehicle for specific events (e.g., when a sensor exceeds a threshold) or periodically and reported based on control parameters when communications is available. Traffic–related data includes snapshots of measured speed and heading and events including starts and stops, speed changes, and other vehicle control events. Environmental data may include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti–lock brake status, 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.

vehicle situation data parameters  (Planned)  Applicable ITS Standards

A request for vehicle situation data that includes parameters used to control the data that is reported and the flow of data reported by the vehicle. This flow identifies the type of data/snapshots that are requested and reporting parameters such as snapshot frequency, filtering criteria (data thresholds for reporting), and reporting interval.
