The 'Basic Maint and Constr Vehicle' represents the maintenance, construction, or other specialized vehicle or equipment that hosts the on-board equipment that provides ITS functionality. It includes the databus, actuators, and other access points that are used by the on-board equipment to monitor and control the host vehicle systems. For example, the interface to this physical object is used to control the operation of the snow plow and monitor the amount of materials (e.g., sand or salt) on-board.
