Abstract

An evaluation information posting device determines a rest state of a vehicle on the basis of rest information, determines a facility at which the vehicle has stopped off by using position information showing a rest position of the vehicle, map information including facility information about facilities located in an area surrounding the position shown by this position information, and a keyword about a facility at the rest position of the vehicle, and, by using both stop-off facility information about the facility which is a result of the determination, and a keyword about an evaluation which is provided for this facility, generates evaluation information about the stop-off facility and posts this evaluation information to an evaluation information managing server.
