Program and information processing method for determining a travel route of a ride-sharing vehicle

A non-transitory computer readable storage medium storing a computer-executable program that, when executed, causes an information processing device communicable with a server configured to manage a travel plan of a specific vehicle, to execute:

• a step of receiving information about the travel plan from the server;
• a first display step of displaying, on a display screen, a plurality of stoppage points of the specific vehicle on an area map, which are geographic locations, and at least part of a travel route passing through a subset of the plurality of stoppage points, based on the information about the travel plan after a wide area map which is wider than the area map is displayed on the display screen;
• an operation step of receiving an input to the information processing device to designate one of the plurality of stoppage points on the display screen or a point other than the plurality of stoppage points;
• a step of transmitting a first request to the server when the one of the plurality of stoppage points is designated, the first request being a request to modify the travel plan so that a passenger of the specific vehicle gets on the specific vehicle or gets off the specific vehicle at the one of the plurality of stoppage points;
• a step of transmitting a second request to the server when the point other than the plurality of stoppage points is designated, the second request being a request to modify the travel plan so that the specific vehicle travels through the point other than the plurality of stoppage points as an additional stoppage point and the passenger gets on the specific vehicle or gets off the specific vehicle at the additional stoppage point;
• and
• a second display step of displaying, on the display screen, the modified travel plan guiding the specific vehicle through the one of the plurality of stoppage points or the additional stoppage point, wherein:
• the subset of the plurality of stoppage points has fewer stoppage points than the plurality of stoppage points, and
• in the operation step, the point other than the plurality of stoppage points is selectable from an area other than a particular area on a map;
• and the particular area is an area within a predetermined distance from a respective stoppage point of the plurality of stoppage points.
