Abstract: An information processing device (2000) includes an acquisition unit (2020) and a learning unit (2040). The acquisition unit (2020) acquires one or more pieces of action data. The action data are data each piece of which associates a state vector representing a state of an environment with an action that is performed in a state represented by the state vector. The learning unit (2040) generates a policy function P and a reward function r through imitation learning using the acquired action data. The reward function r outputs, when given a state vector S as input, a reward r(S) that is acquired in a state represented by the state vector S. The policy function accepts, as input, an output r(S) of the reward function upon input of a state vector S and outputs an action a=P(r(S)) to be performed in a state represented by the state vector S.

Abstract: A route analysis device of the present invention is for analyzing a route from a departure location to a destination. This device includes: a traffic condition prediction unit (11) that, for each of multiple future times, predicts a traffic condition in each of multiple zones that exist from the departure location to the destination; an estimation unit (12) that selects one of the traffic conditions predicted for each of the future times in accordance with the elapsed time from when prediction was performed by the traffic condition prediction unit (11), and, using the selected traffic condition, estimates a travel time that corresponds to the elapsed time in each of the zones; and a route analysis unit (13) that, using the travel times estimated for the zones, calculates the smallest value of the travel time from the departure location to the destination.

Abstract: The purpose of the present invention is to preserve quality of service which a toll road provides. Provided is a traffic control system 1, comprising a prediction unit 210 and a control unit 230. The prediction unit 210 predicts a traffic state on one path among a plurality of paths from a first point to a second point. If the predicted traffic state on the one path does not satisfy a prescribed service level, the control unit 230 controls quantities of apportionment of vehicles among the plurality of paths on the first point such that the traffic state on the one path satisfies the prescribed service level.

Abstract: A toll control apparatus 100 includes a traffic volume prediction unit 10 that predicts a future overall traffic volume on a first road 401 and a second road 402, a toll control unit 20 that outputs, with the predicted overall traffic volume and a predetermined road toll as inputs, a future traffic volume and a predicted traveling speed on the second road for a case where a toll on the second road is set to the predetermined road toll, and a toll optimization unit 30. The toll optimization unit 30 sets one or more road toll candidates, selects a road toll candidate for which the predicted traveling speed obtained by inputting the road toll candidate to the toll control unit 20 is greater than or equal to a threshold value, and sets the road toll candidate that maximizes the toll revenue for the second road among the selected road toll candidates.

Abstract: A traffic control support system for accurately predicting, when an irregular event occurs, a traffic state and an influence of the event on the traffic state, is provided. The traffic control support system includes calculation means for calculating, based on a relation between a flow rate and a density of traffic and a predicted value of the density in a regular state in each of a plurality of locations, an estimated value of the density in each of one or more locations at a specific time after an event starting time representing a time at which an irregular event occurs in at least one of the plurality of locations, and display control means for displaying an influence of the irregular event on traffic in each of one or more locations, based on an estimated value of the density.
