Interface: Private Road Weather Information and Maintenance Systems - MTO Maintenance Vehicles
Architecture Flow Definitions
environmental sensor data (Existing (Partial))
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 en
infrastructure conditions data (Proposed)
Current condition of pavement, bridges, culverts, signs, and other roadway infrastructure as measured by on-board sensors or read from infrastructure-based sensors. The data may include raw data or images (e.g., photo logs) that indicate the current stat
maint and constr dispatch information (Existing (Partial))
Information used to dispatch maintenance and construction vehicles, equipment, and crews and information used to keep work zone crews informed. This information includes routing information, traffic information, road restrictions, incident information, e
maint and constr dispatch status (Existing (Partial))
Current maintenance and construction status including work data, operator status, crew status, and equipment status.
maint and constr vehicle conditions (Proposed)
Vehicle diagnostics information that is collected, filtered, and selectively reported by a maintenance and construction vehicle. The information includes engine temperature, mileage, tire wear, brake wear, belt wear, and any warnings or alarms concerning
maint and constr vehicle location data (Proposed)
The current location and related status (e.g., direction and speed) of the maintenance/construction vehicle.
maint and constr vehicle operational data (Existing (Partial))
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
maint and constr vehicle system control (Existing (Partial))
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 sp
work zone status (Proposed)
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.
work zone warning status (Proposed)
Status of a work zone safety monitoring and warning devices. This flow documents system activations and includes additional supporting information (e.g., an image) that allows verification of the alarm.
