Local Jurisdiction Maintenance 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.

IDRequirementStatus
1The vehicle shall remotely control barrier systems. Barrier systems include automated or remotely controlled gates, barriers and other systems that manage entry to roadways.Existing
2The vehicle shall collect barrier system operational status.Existing
3The vehicle shall collect barrier system fault data.Existing

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.Existing
2The 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.Existing
3The maintenance and construction vehicle shall monitor materials information including remaining quantity and current application rate of materials on the vehicle.Existing
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.Existing

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.Existing
2The maintenance and construction vehicle shall send the time stamped vehicle location to the controlling center.Existing

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.Existing
3The maintenance and construction vehicle shall the vehicle diagnostic and safety information to an equipment repair facility.Existing
4The maintenance and construction vehicle shall send the vehicle diagnostic and safety information to the controlling maintenance center.Existing

Functional Area: MCV Work Zone Support

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

IDRequirementStatus
1The 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.Existing
2The maintenance and construction vehicle shall provide an interface for field personnel to input status of their work zone activities.Existing
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.Existing
