Abstract: A vehicle operation management device (3) manages operation of a vehicle (2). The vehicle operation management device (3) includes an operation plan creation unit (31) that creates an operation plan of the vehicle (2) on the basis of a schedule for getting in and out of the vehicle (2) of a user who wants to ride the vehicle (2), and a travel instruction unit (34) that instructs the vehicle (2) to travel according to the operation plan. When the user of the vehicle (2) is scheduled to get in the same vehicle (2) again after getting out of the vehicle (2), the operation plan creation unit (31) proposes, to the user, operation details of the vehicle (2) during a period of time from when the user gets out of the vehicle (2) to when the user gets in the vehicle (2) next, and creates the operation plan including the operation details proposed.

Abstract: A detection device includes processing circuitry configured to acquire sensor information from at least one sensor; the at least one sensor configured to be disposed on at least one of balustrades erected on both right and left sides with respect to a moving direction of steps of at least one passenger conveyor, each of the balustrades including a plurality of side plates; determine whether or not the detection target is a designated target to be warned on a basis of the acquired sensor information; and display a warning image indicating the designated target on a display device in a case where the processing circuitry determines that the detection target is the designated target.

Abstract: An on-demand vehicle management device includes a communication unit that receives detection data output by at least one of a sensor provided in or on an on-demand vehicle or a sensor installed along a travel route, a categorization information generation unit that recognizes a user, based on the detection data, and generates categorization information that associates an object represented by information included in the detection data with the user, as a possession of the user, a categorization information comparison unit that determines whether a change has occurred in a situation of the possession by making a comparison, on a per user basis, between the categorization information as of before the user gets on the on-demand vehicle and the categorization information as of when the user gets off the on-demand vehicle, and a warning notification unit that outputs warning information when it is determined that the change has occurred.
