Road management system, road management method, and road management program

摘要

PROBLEM TO BE SOLVED: To provide a road management system capable of extracting a road section whose need for repair exceeds a threshold value in consideration of priority of road management at the time of occurrence of disaster or vulnerability of each region to disaster. A road management system 10 stores measurement information 30 of road surface properties, and a plurality of information 40 indicating either priority of road management at the time of disaster occurrence or degree of vulnerability to each area for disaster. Based on the storage device 12, one or more pieces of information 40 selected from the plurality of pieces of information 40, and the measurement information 30, repairs are performed from roads whose priority is equal to or higher than a threshold value or whose degree of vulnerability is equal to or higher than a threshold value. The arithmetic unit 11 is provided for extracting a road section whose necessity level exceeds a threshold value. [Selection diagram]
