Statistical processing server, probe information statistical method and probe information statistical program

摘要

A statistical server obtains probe data from a navigation device in a vehicle and performs statistical processing on the probe data. The statistical server stores vehicle attribute data from the navigation device and probe data, which measured vehicle behavior that varies depending on the vehicle attribute. An accumulated quantity of probe data is obtained for each vehicle attribute category, and the size of a category whose probe data is targeted for statistical processing is determined depending on the accumulated quantity. The statistics of the probe data belonging to the category targeted for statistical processing are subsequently calculated, and distribution data corresponding to the vehicle attribute generated. The distribution data is then sent to the navigation device belonging to the applicable category.
