At that time, maintenance was not considered enough. After many bridges in the United States without maintenance were rapidly deteriorated and caused tragic accidents, Japan started to establish a countermeasure to prevent to be "Japan in ruins." Because most municipalities had not even inspected bridges although they are in charge of more than half of bridges in Japan, central government decided to subsidize local governments who inspect bridges and make plans for maintaining them for long term by “preventive maintenance”. After this policy, most managers have inspected and made their own manuals. The plans should fit to each government’s capacity to manage sustainably. However, some plans are made without considering its own circumstances. This research assess the plans from the perspective of physical conditions, potential of managers, and social conditions using indexes to propose the proper way to manage bridges in municipalities.}, publisher = {Society for Social Management Systems}, title = {AN INVESTIGATION OF ROAD BRIDGE MAINTENANCE SYSTEM IN JAPAN IN DEVELOPED SOCIETY}, volume = {9}, year = {2014} }
