1. A driving range calculation apparatus for calculating a range reachable by a vehicle that travels by using stored energy, comprising:

  • a storage part for storing beforehand, as an energy consumption graph, amounts of energy consumed by a vehicle traveling in both directions along road links on a map rendered in a manner that road links couple road nodes; and

    a processing part, which traces a road link from a specified start point location peripherally, calculates, for each road node, a first integration value obtained by integrating amounts of energy in a direction moving away from the start point location on the energy consumption graph and a second integration value obtained by integrating amounts of energy in a direction moving toward the start point location on the energy consumption graph, and based on a relationship between the sum of the first integration value and the second integration value and a given specified amount of energy for each road node, decides a round-trip driving range which is a range within which the vehicle is able to return to the start point location by using the specified amount of energy.
