  • Publication number: 20240054889
    Abstract: A traffic data acquisition unit acquires traffic volume data. A required time acquisition unit acquires an actual value of a required time. A traffic volume calculation unit calculates an inflow traffic volume of vehicles flowing into each using the traffic volume data and the actual value of the required time. A traffic state prediction unit calculates, for each route, a predicted value of the required time in view of the calculated inflow traffic volume and a predicted value of the required time when the inflow traffic volume is changed using a traffic model generated in advance. An amount of change calculation unit calculates, for each route, an amount of change in the predicted value of the required time when the inflow traffic volume is changed.
