Title:
PATH-SPECIFIC TRAFFIC VOLUME ESTIMATING DEVICE, PATH-SPECIFIC TRAFFIC VOLUME ESTIMATING METHOD, AND PATH-SPECIFIC TRAFFIC VOLUME ESTIMATING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/235105
Kind Code:
A1
Abstract:
According to the present invention, a path-specific traffic volume estimating unit (130) estimates a path-specific traffic volume, which is the traffic volume of observation objects at each time point for each path candidate, on the basis of observation value data which represents the number of the observation objects at each time point for each of a plurality of observation points, observation point-specific reliability data which represents the reliability of the observation value data at each time point for each of the plurality of observation points, and a path candidate list which indicates a set of path candidates along which the observation objects move.
