Abstract: A management assistance system according to an aspect of the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: detect a road surface mark and a degree of abrasion of the road surface mark from a road surface image taken of a road surface; determine, based on the degree of abrasion of the road surface mark, whether the road surface mark is to be repainted; and calculate, based on the road surface mark determined to be repainted, an amount of paint to be used for repainting the road surface mark.

Abstract: An effect determination system according to the present invention includes: a memory configured to store instructions; and one or more processors configured to execute the instructions to: acquire a predicted displacement of a structure after an event, the predicted displacement being a displacement of the structure on a ground surface and having been predicted based on a pre-event displacement acquired before the event related to a ground of the structure; acquire a post-event displacement of the structure based on an observation result of the ground surface observed after the event; and determine an effect of the event on the structure based on the predicted displacement and the post-event displacement.

Abstract: A repair assistance system according to an aspect of the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: detect unrepaired road surface deterioration from a road surface image obtained by imaging a road surface; determine an area of road surface deterioration to be subjected to temporary repair based on the detected unrepaired road surface deterioration; and calculate an amount of a material to be used for the temporary repair of the road surface based on the determined area.

Abstract: A route generation system includes a diagnosis unit, a generation unit, and an output unit. The diagnosis unit performs a diagnosis to estimate a deterioration degree of a road surface from an image to be monitored. The generation unit generates a travel route based on the deterioration degree of the road surface for each point diagnosed by the diagnosis unit and information regarding a road environment affecting the diagnosis for each point, the travel route being generated for capturing another image used for another diagnosis. The output unit outputs the generated travel route.
