1. A link travel time calculation device comprising:

  • a collection element for collecting a travel position and a transit time at the travel position in each vehicle, which are measured individually among a plurality of vehicles; and

    a link travel time calculation element,wherein the link travel time calculation element calculates a total travel time interval of all sections based on the travel position and the transit time, which are collected by the collection element in a predetermined time period,wherein the all sections includes an object link, an upstream section disposed on an upstream side of the object link, and a downstream section disposed on a downstream side of the object link,wherein the link travel time calculation element calculates a first travel time interval of the upstream section based on the travel position and the transit time,wherein the link travel time calculation element calculates a second travel time interval of the downstream section based on the travel position and the transit time, andwherein the link travel time calculation element calculates a travel time interval of the object link with respect to the predetermined time period by subtracting a sum of the first travel time interval and the second travel time interval from the total travel time interval.
