Information system and terminal device

Abstract

To perform rough road determination of a guided route by utilizing the fact that a route different from the guided route is selected by a driver.SOLUTION: An information system A includes a terminal device 2 and a server 1. The terminal device 2 includes: a terminal storge unit 211 which stores set route information; a position acquisition unit 212 which acquires position information; an imaging unit 222 which accumulates images acquired while traveling, in association with the position information; a determination unit 215 which determines route deviation by using the route information and the position information; and an image transmission unit 224 which transmits, to the server 1, the images acquired by the imaging unit 222 while traveling on the route when route deviation occurs. The server 1 includes a rough road determination unit 131 which inputs the received images to a learning model acquired by a learning function of machine learning by using two or more pieces of training data, and outputs a score indicating a degree of rough road.SELECTED DRAWING: Figure 2
