  • Management device of autonomous driving vehicle
    Patent number: 11941549
    Abstract: The management device of an autonomous driving vehicle includes a congestion rate calculation unit and a waiting place setting unit. The congestion rate calculation unit is able to calculate the congestion rate of a parking lot adjoining each of a plurality of commercial facilities. In a case where the congestion rate of a neighbor parking lot, or a parking lot in the neighborhood of a boarding place contained in reservation information for an autonomous driving vehicle reserved for dispatch, during a waiting time period before the scheduled boarding time, is less than a congestion threshold, the waiting place setting unit sets the neighbor parking lot as a waiting place for the autonomous driving vehicle to wait during the waiting time period.
