Information Flow Definitions
asset location safety warning (Planned)
Notification that asset locations have been identified that are either in or too close to designated travel lanes. This flow identifies the assets and their locations to work crews that can address the detected asset location issues.
asset locations (Planned)
Aggregate collected data including identified assets and their locations.
environmental sensor data (Existing)
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 (Future)
Data used to configure and control environmental sensors.
infrastructure conditions data (Future)
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 status of the infrastructure.
maint and constr dispatch information (Existing)
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, environmental information, decision support information, maintenance schedule data, dispatch instructions, personnel assignments, alert notifications, and corrective actions.
maint and constr dispatch status (Existing)
Current maintenance and construction status including work data, operator status, crew status, and equipment status.
maint and constr vehicle conditions (Existing)
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 the operational condition of the vehicle and ancillary equipment.
maint and constr vehicle location data (Existing)
The current location and related status (e.g., direction and speed) of the maintenance/construction vehicle.
maint and constr vehicle operational data (Existing)
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 (Future)
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)
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 device control (Future)
Data used to configure and control work zone safety monitoring and warning devices.
work zone warning status (Future)
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.
