Efforts for Efficient Maintenance at Metropolitan Expressway

Abstract

 Metropolitan Expressway has a high proportion of structures such as bridges and tunnels. Therefore, meticulous maintenance is required. Furthremore, it is expected that the number of engineers involved in maintenance and operation will decrease as the working-age population declines, in addition to the increase in damage due to the aging structures. Thus, it is necessary to consider and implement more efficient maintenance methods for ensuring the safety and security of structures. Moreover, in order to quickly grasp the damage status of structures, it is essential to invesitgate and introduce methods of collecting information more quickly in terms of dizaster response. This paper reports overview and effects of introduced new technology including ICT and various new maintenance technology which realize efficient maintenance.
