Regional Maintenance and Construction Vehicles - Maintenance and Construction Vehicle Functionality

Subsystem Description

The Maintenance and Construction Vehicle Subsystem (MCVS) resides in a maintenance, construction, or other specialized service vehicle or equipment and provides the sensory, processing, storage, and communications functions necessary to support highway maintenance and construction. All types of maintenance and construction vehicles are covered, including heavy equipment and supervisory vehicles. The subsystem provides two-way communications between drivers/operators and dispatchers and maintains and communicates current location and status information. A wide range of operational status is monitored, measured, and made available, depending on the specific type of vehicle or equipment. For example, for a snow plow, the information would include whether the plow is up or down and material usage information. The subsystem may also contain capabilities to monitor vehicle systems to support maintenance of the vehicle itself and other sensors that monitor environmental conditions including the road condition and surface weather information. This subsystem can represent a diverse set of mobile environmental sensing platforms, including wheeled vehicles and any other vehicle that collects and reports environmental information.

Functional Area: MCV Barrier System Control

Control automatic or remotely controlled gates and other barrier systems from a maintenance and construction vehicle.

Functional Area: MCV Environmental Monitoring

On-board systems that collect environmental and road condition data (including road surface or air temperature, wind speed, and road traction information - spatially located and time stamped) from sensors on-board the maintenance vehicle or located at the roadway.

6The maintenance and construction vehicle shall be capable of accepting sensor control data from the center.Planned
7The maintenance and construction vehicle shall provide control signals to environmental sensors located at the roadway.Planned
8The maintenance and construction vehicle shall transmit environmental sensor data to roadside equipment. The sensor data includes location and timestamp information.Planned

Functional Area: MCV Roadway Maintenance and Construction

On-board systems that support routine non-winter maintenance on the roadway or right-of-way. Includes landscape maintenance, hazard removal (roadway debris, dead animals), routine maintenance activities (roadway cleaning, grass cutting), and repair and maintenance of equipment on the roadway.

IDRequirementStatus
1The maintenance and construction vehicle shall track the location and status of safety systems on-board the vehicle.Planned
4The maintenance and construction vehicle shall respond to dispatch information from the center, presented to the vehicle operator for acknowledgement and returning status.Planned
5The maintenance and construction vehicle shall send operational data to the center including the operational state of the maintenance equipment (e.g., blade up/down, spreader pattern), types and quantities of materials used for construction and maintenance activities, and a record of the actual work performed.Planned

Functional Area: MCV Vehicle Location Tracking

On-board systems to track vehicle location and reports the position and timestamp information to the dispatch center.

IDRequirementStatus
1The maintenance and construction vehicle shall track its current location.Planned
2The maintenance and construction vehicle shall send the time stamped vehicle location to the controlling center.Planned

Functional Area: MCV Vehicle Safety Monitoring

On-board systems to detect vehicle intrusions and warn crew workers and drivers of imminent encroachment. Crew movements are monitored so that the crew can be warned of movement beyond the designated safe zone. Used for stationary work zones or in mobile applications where a safe zone is maintained around the moving vehicle.

Functional Area: MCV Vehicle System Monitoring and Diagnostics

On-board sensors capable of monitoring the condition of each of the vehicle systems and diagnostics that can be used to support vehicle maintenance.

IDRequirementStatus
1The maintenance and construction vehicle shall collect vehicle diagnostics and operating status data from the maintenance vehicle platform including engine temperature, mileage, tire wear, brake wear, belt wear, and other operational status measures as well as the status of maintenance and construction-specific systems on the vehicle.Existing
2The maintenance and construction vehicle shall use the diagnostic and status information to support scheduling vehicle maintenance, monitoring safety status, and informing the vehicle operator of the conditions.Planned
3The maintenance and construction vehicle shall the vehicle diagnostic and safety information to an equipment repair facility.Planned
4The maintenance and construction vehicle shall send the vehicle diagnostic and safety information to the controlling maintenance center.Planned

Functional Area: MCV Winter Maintenance

On-board systems that support snow plow operations and other roadway treatments (e.g., salt spraying and other material applications). Supports information sharing between snow plows.

IDRequirementStatus
1The maintenance and construction vehicle shall track the location and status of safety systems on-board the vehicle.Existing
3The maintenance and construction vehicle shall monitor materials information including remaining quantity and current application rate of materials on the vehicle.Planned
4The maintenance and construction vehicle shall respond to dispatch information from the center, presented to the vehicle operator for acknowledgement and returning status.Existing
5The maintenance and construction vehicle shall send operational data to the center including the operational state of the maintenance equipment (e.g., blade up/down, spreader pattern), types and quantities of materials used for construction and maintenance activities, and a record of the actual work performed.Planned
6The maintenance and construction vehicle shall exchange operational and environmental data with other maintenance and construction vehicles. Operational data includes operational state of the maintenance equipment (e.g., blade up/down, spreader pattern, equipment configuration) and a record of the actual work performed while the environmental data includes environmental sensor data collected on-board a maintenance and construction vehicle, either raw or processed data.Planned

Functional Area: MCV Work Zone Support

On-board systems that provide communications and support for local management of a work zone.

IDRequirementStatus
2The maintenance and construction vehicle shall provide an interface for field personnel to input status of their work zone activities.Planned
3The maintenance and construction vehicle shall collect inputs from field personnel and from work zone devices on-board the maintenance and construction vehicle and send them to the controlling center.Planned
