Abstract
A traffic data prediction device includes an original link traffic data storage unit (103) for storing traffic data per original link as a predetermined road link, an extended link generation unit (104) for generating an extended link from the original links, and an extended link traffic data prediction unit (108) for predicting traffic data per extended link generated in the extended link generation unit (104) by use of traffic data per original link. The extended link generation unit (104) decides the original links for generating the extended link based on data indicating a predictive accuracy of traffic data in a combined link combining the selected original links, and generates the extended link made of the decided original links as elements.
