Architecture Flow Definitions
environmental sensor data (Existing) Applicable ITS Standards
Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.
environmental sensors control (Existing) Applicable ITS Standards
Data used to configure and control environmental sensors.
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.
road weather advisories (Planned) Applicable ITS Standards
Segment–specific weather and road conditions including real–time advisories of deteriorating road and weather conditions, medium–term advisories for the next 2–12 hours, and long–term advisories more than 12 hours into the future. The advisories may include advisories that are issued by the RSE based on locally collected environmental data (e.g., an ice on bridge advisory).
traffic gap information (Planned) Applicable ITS Standards
Measured gap to the next approaching vehicle per lane and direction of travel
vehicle environmental data (Existing) 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 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).
vehicle situation data parameters (Existing) 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.
wrong way vehicle detected (Planned) Applicable ITS Standards
Notification that a vehicle has been detected traveling in the wrong direction. This can be a direct report by an equipped vehicle that is being driven in the wrong direction or a report of a non–equipped vehicle that has been detected traveling in the wrong direction. It includes the current location, speed, acceleration, and heading of the wrong way vehicle.
