PROBLEM TO BE SOLVED: To allow a link travel time to be calculated accurately by reflecting the traffic condition to real-time. SOLUTION: In a first calculation method, the link travel time of an object link is calculated by subtracting the sum of a section 1 travel time of an upstream section and a section 2 travel time of a downstream section from the total travel time of all sections consisting of the object link, the upstream section, and the downstream section. In a second calculating method, the link travel time of the object link is calculated, by subtracting the total travel time of all sections from the sum of the section 1 travel time, consisting of the object link and an upstream link and the section 2 travel time consisting of the object link and a downstream link. In a third calculation method, the link travel time of the object link is calculated by subtracting the section 1 travel time of the upstream section from the total travel time of all sections consisting of the object link and the upstream section.
