An information processing apparatus acquires a route score including a travel cost and a coefficient for each of a plurality of driving route candidates. The information processing apparatus acquires a user score including an individual rate that is a time-cost conversion rate particular to a mobile user and a weight application rate particular to the mobile user. Based on the respective route scores of the plurality of driving route candidates and the user score of the mobile user, the information processing apparatus converts the travel cost of each of the plurality of driving route candidates into a corresponding cost that is a cost obtained by reflection of the time-cost conversion rate and the weight application rate of the mobile user in the travel cost. The information processing apparatus determines a recommendation order of the plurality of driving route candidates based on the corresponding costs of the plurality of driving route candidates.

Information processing apparatus, information processing method and non-transitory memory medium

A traffic volume determination system includes: a storage device configured to store a first table configured to store information identifying a first link and a second link having a correlation degree, which exceeds a threshold, of a traffic volume, and a second table configured to store information indicating a first reference traffic volume and information indicating a second reference traffic volume; and a computer configured to determine that the first link is closed when a probability that an first event and a second event occur at a same time is statistically significantly small, the first event being an event in which an actual traffic volume of the first link is significantly lower than the first reference traffic volume, the second event being an event in which an actual traffic volume of the second link is significantly higher than the second reference traffic volume.

Traffic volume determination system utilizing road-to-vehicle communication

A traffic volume determination system includes a table configured to store information indicating a statistical proportion of vehicles flowing into an exit link exiting from a node, among vehicles traveling on an entry link entering the node; an estimation unit configured to calculate an estimated value of a traffic volume of vehicles traveling on the exit link from an actual traffic volume of the vehicles traveling on the entry link, with reference to the table; and a determination unit configured to determine that the exit link is closed when the actual traffic volume of the vehicles traveling on the exit link is smaller than the estimated value.

Traffic volume determination system, traffic volume determination method, and non-transitory computer-readable storage medium storing traffic volume determination program

A traffic volume determination system includes a processor configured to: calculate, while taking account of a change between a past traffic volume and a current traffic volume of vehicles passing through an area around a link, an estimated value of the current traffic volume of the vehicles passing through the link from the past traffic volume of the vehicles passing through the link; and determine that the link is closed when a current actual traffic volume of the vehicles passing through the link is smaller than the estimated value of the current traffic volume of the vehicles passing through the link by more than a statistical error.
