Link travel time calculation device and method for calculating link travel time interval

摘要

A link travel time calculation device includes: a collection element for collecting a travel position and a transit time in each vehicle; and a link travel time calculation element. The calculation element calculates a total travel time interval of all sections based on the travel position and the transit time in a predetermined time period. The calculation element calculates a first travel time interval of an upstream section and a second travel time interval of a downstream section based on the travel position and the transit time. The 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.
