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.

The autonomous vehicle is provided with an autonomous travel control unit (steering control unit) configured to, when the passenger vehicle is stopped, cause the autonomous vehicle to pull up alongside the passenger vehicle such that an entrance (second entrance) of the autonomous vehicle is placed next to an entrance (first entrance) of the passenger vehicle.

Abstract: A solid-state imaging device is provided with a substrate in which a plurality of photoelectric conversion parts is formed, and with a light incident surface layer formed on the light incident surface of the substrate. The substrate and the light incident surface layer include a compound semiconductor containing germanium. A concentration of the germanium in the light incident surface layer increases toward a surface side remote from the substrate. At the time of production, isotropic etching is performed after a lattice-shaped groove is formed in the light incident surface layer, so that a groove width of the lattice-shaped groove increases toward a light incident surface side of the light incident surface layer due to a difference in etching rate attributed to the concentration of the germanium, and an uneven structure having a tapered bump can thus be formed relatively easily.
