A method and apparatus for duplex copying providing enhanced time to first copy is disclosed. The information included in the provision request from a route search terminal is acquired, calculation processing of the environmental load value of the relevant vehicle and the environmental load value of other vehicle by which it is generated with movement of a relevant vehicle from the acquired information is carried out using an environmental load calculation unit. Therefore, a profile intermediate the arsenic only and the phosphorus only can be achieved. In one embodiment, the internal solution ground can be electrically isolated through a capacitor or, alternately, a capacitor and resistor in parallel. These analytical capabilities allow the fleet management system to assist fleet managing entities, or other entities, in analyzing driver performance, reducing fuel and maintenance costs, and improving route planning.
