County and City 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 Vehicle Location Tracking
On-board systems to track vehicle location and reports the position and timestamp information to the dispatch center.
| ID | Requirement | Status |
|---|---|---|
| 1 | The maintenance and construction vehicle shall track its current location. | Existing |
| 2 | The maintenance and construction vehicle shall send the time stamped vehicle location to the controlling center. | Existing |
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 |
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 |
|---|---|---|
| 1 | The maintenance and construction vehicle shall track the location and status of safety systems on-board the vehicle. | Existing |
| 3 | The maintenance and construction vehicle shall monitor materials information including remaining quantity and current application rate of materials on the vehicle. | Existing |
| 4 | The maintenance and construction vehicle shall respond to dispatch information from the center, presented to the vehicle operator for acknowledgement and returning status. | Existing |
