Local 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.

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

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. Existing

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. Medium-term
2 The maintenance and construction vehicle shall provide an interface for field personnel to input status of their work zone activities. Medium-term
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. Medium-term
