Municipal PWD Vehicles - Maintenance and Construction Vehicle Functionality
Subsystem Description
This subsystem 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 |
|---|---|---|
| 1 | The maintenance and construction vehicle shall track the location and status of safety systems on-board the vehicle. | Planned |
| 2 | The maintenance and construction vehicle shall respond to control information from the center to allow remote operation of the on-board vehicle systems. These systems include routine maintenance equipment for cutting, repairs, hazard removal, etc. | Planned |
| 3 | The maintenance and construction vehicle shall monitor materials information including remaining quantity and current application rate of materials on the vehicle. | Planned |
| 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 |
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 |
| 2 | The 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 |
| 3 | The maintenance and construction vehicle shall send 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 |
Functional Area: MCV Work Zone Support
On-board systems that provide communications and support for local management of a work zone.
| ID | Requirement | Status |
|---|---|---|
| 1 | The maintenance and construction vehicle shall monitor, operate, and control work zone devices located at or alongside the roadway. The devices operated on board the vehicle include driver information devices (e.g. dynamic message signs) and work zone intrusion detection and alert devices. | Planned |
| 2 | The maintenance and construction vehicle shall provide an interface for field personnel to input status of their work zone activities. | Planned |
| 3 | The 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 |
