An information processing system includes a center server, a first moving object that performs communication with the center server, and a second moving object that performs communication with the center server. The first moving object includes a submission information acquisition unit that acquires submission information related to a travel guiding, and a submission information transmission unit that transmits the submission information to the center server. The center server includes a guiding information accumulation unit that accumulates guiding information which is based on the submission information. The second moving object includes a travel guiding execution unit that executes the travel guiding for the second moving object with respect to the traveling route to the preset destination. The travel guiding execution unit executes the travel guiding using the guiding information of the guiding information accumulation unit.

A section setting method calculates information relating to an attainable actual fuel efficiency under a vehicle operation performed in consideration of fuel efficiency. To that end, the section setting method collects fuel-efficiency information that is information relating to the fuel efficiency required for a movement from a start point to a destination point of the vehicle, which is obtained under a plurality of kinds of vehicle operations, along with positional information of the vehicle at each time. The section setting method compares change pattern parts of the collected fuel-efficiency information with each other, thereby sequentially connecting the change pattern parts of the fuel-efficiency information from the start point to the destination point. The section setting method sets, as a section used to calculate the actual fuel efficiency, a section obtained by sectioning at points corresponding to the connection points of the change pattern parts connected.

A section defining method separates a road between a departure point and a destination point into a plurality of links under a predetermined condition and defines a section based on a link cost, which is an index indicating ease of travel and set for each link. The section is used to generate guide information provided to a driver of a vehicle. The section is defined by combining, among the plurality of links between the departure point and the destination point, at least two continuous links that yield a decrease in standard deviation, which is based on sums of the link costs.
