Abstract: An apparatus includes an acquisition unit configured to acquire probe information of a probe vehicle traveling on inflow road to intersection and information processing unit configured to execute calculation process for calculating delay time per vehicle due to waiting at traffic signal on inflow road, by using probe information as source data. First calculation process includes calculating, based on probe information, plurality of section speeds, each an average speed of a vehicle over corresponding one of plurality of sections, obtained by dividing inflow road, second process for calculating, based on plurality of section speeds, total number of sections that is the total number included in traffic-signal waiting section of inflow road, third process for calculating, based on total sections, average travel time over traffic-signal waiting section, and fourth process for calculating delay time, based on total sections and average travel time over traffic-signal waiting section.

Abstract: Provided is an information processing apparatus including: an operation unit configured to receive an operation input regarding a first extraction condition; and a control unit configured to perform predetermined information processing, based on the first extraction condition. The information processing includes: a process of extracting one or a plurality of intersection nodes corresponding to intersections that conform to the first extraction condition, from among nodes included in map data; a process of acquiring time-series data of traffic information from a database in which the time-series data of the traffic information is accumulated; and a process of selecting, from among the one or the plurality of intersection nodes having been extracted, a target intersection that requires adjustment of a constant of a traffic signal controller, based on the acquired time-series data of the traffic information, and outputting the selected target intersection to a display unit.
