Architecture Flow Definitions
environmental sensor data (Planned) 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 (Planned) Applicable ITS Standards
Data used to configure and control environmental sensors.
maint and constr vehicle location data (Planned) Applicable ITS Standards
The current location and related status (e.g., direction and speed) of the maintenance/construction vehicle.
maint and constr vehicle operational data (Planned) Applicable ITS Standards
Data that describes the maintenance and construction activity performed by the vehicle. Operational data includes materials usage (amount stored and current application rate), operational state of the maintenance equipment (e.g., blade up/down, spreader pattern), vehicle safety status, and other measures associated with the operation of a maintenance, construction, or other special purpose vehicle. Operational data may include basic operational status of the vehicle equipment or a more precise record of the work performed (e.g., application of crack sealant with precise locations and application characteristics).
maint and constr vehicle system control (Planned) Applicable ITS Standards
Configure and control data that supports remote control of on-board maintenance and construction vehicle systems and field equipment that is remotely controlled by the vehicle. For example, the data can be used to adjust material application rates and spread patterns.
work zone status (Planned) Applicable ITS Standards
Current work zone status including current location (and future locations for moving work zones), impact to the roadway, required lane shifts, expected time(s) and duration of impact, anticipated delays, alternate routes, and suggested speed limits.
