NMDOT District 1 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 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.
| ID | Requirement | Status |
|---|---|---|
| 4 | The maintenance and construction vehicle shall respond to dispatch information from the center, presented to the vehicle operator for acknowledgement and returning status. | Planned |
| 5 | The 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 |
| 6 | The maintenance and construction vehicle shall track the location and status of systems on-board the vehicle. | 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.
| ID | Requirement | Status |
|---|---|---|
| 2 | The 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.
| ID | Requirement | Status |
|---|---|---|
| 1 | The maintenance and construction vehicle shall detect that a vehicle has intruded upon the boundary of a work zone. The boundary of the work zone represents an area around the maintenance and construction vehicle, which may be stationary or moving. | Planned |
| 2 | The maintenance and construction vehicle shall receive work zone warnings from the field equipment at the roadside, other maintenance and construction vehicles. | Planned |
| 5 | The maintenance and construction vehicle shall provide status of the work zone warning systems to the center. | Planned |
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.
| ID | Requirement | Status |
|---|---|---|
| 1 | The 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. | Planned |
| 3 | The maintenance and construction vehicle shall the vehicle diagnostic and safety information to an equipment repair facility. | Planned |
| 4 | The maintenance and construction vehicle shall send the vehicle diagnostic and safety information to the controlling maintenance center. | Planned |
| 5 | The maintenance and construction vehicle shall send the vehicle diagnostic and safety information to an equipment repair facility. | 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.
| ID | Requirement | Status |
|---|---|---|
| 5 | The 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 |
| 6 | The 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 |
| 7 | The maintenance and construction vehicle shall track the location and status of systems on-board the vehicle. | Planned |
Functional Area: MCV Work Zone Support
On-board systems that provide communications and support for local management of a work zone.
| ID | Requirement | Status |
|---|---|---|
| 2 | The maintenance and construction vehicle shall provide an interface for field personnel to input status of their work zone activities. | Planned |
