City of Dallas Maintenance and Construction Vehicles - Maint and Constr Vehicle OBE Functionality
Subsystem Description
The 'Maint and Constr Vehicle OBE' resides in a maintenance, construction, or other specialized service vehicle or equipment and provides the processing, storage, and communications functions necessary to support highway maintenance and construction. All types of maintenance and construction vehicles are covered, including heavy equipment, supervisory vehicles, unmanned remote controlled field maintenance robots, and sensory platforms that may be wheeled or low altitude aerial vehicles (e.g. drones, balloons). The MCV OBE 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. A snow plow for example, would monitor whether the plow is up or down and material usage information. The Maint and Constr Vehicle OBE may also contain capabilities to monitor vehicle systems to support maintenance of the vehicle itself. A separate 'Vehicle OBE' physical object supports the general vehicle safety and driver information capabilities that apply to all vehicles, including maintenance and construction vehicles. The Maint and Constr Vehicle OBE supplements these general capabilities with capabilities that are specific to maintenance and construction vehicles.
Functional Object: MCV Barrier System Control
'MCV Barrier System Control' provides local control of automatic or remotely controlled gates and other barrier systems from a maintenance and construction vehicle. This allows maintenance and construction field personnel (e.g., snow plow operators) to open and close gates and other barrier systems without leaving the vehicle, using V2I Communications to control the barriers.
Functional Object: MCV Roadway Maintenance and Construction
'MCV Roadway Maintenance and Construction' includes the on–board systems that support routine non–winter maintenance on a roadway system or right–of–way. Routine maintenance includes landscape maintenance, hazard removal (roadway debris, dead animals), routine maintenance activities (roadway cleaning, grass cutting), and repair and maintenance of both ITS and non–ITS equipment on the roadway (e.g., signs, traffic controllers, traffic detectors, dynamic message signs, traffic signals, etc.).
Functional Object: MCV Work Zone Support
'MCV Work Zone Support' provides communications and support for local management of a work zone. It supports communications between field personnel and the managing center to keep the center appraised of current work zone status. It controls vehicle–mounted driver information systems (e.g., dynamic message signs) and uses short range communications to monitor and control other fixed or portable driver information systems in the work zone.
