Disaster Risk Management Engineering (West Japan Railway Company)

Public transportation agencies such as railways possess and maintain infrastructures over a wide range of the country, and also provide highly public services to the people. Thus in our laboratory, in order to improve and enhance the safety of these infrastructures, we evaluate the current state of them and then propose the effective counteractions on the basis of the evaluation.

Research Topics

Research on improvement of disaster resistance of transportation infrastructure

With earthquakes and heavy rainfall becoming more intense lately, railway and road infrastructures require improved strength and durability to cope with disaster risks. However, an excessive increase in structural strength is not realistic. This research aims to develop an improved disaster-resistant infrastructure based on the probability of extreme rainfall and earthquakes.

Research on reasonable traffic regulation methods during extreme weather conditions

Society relies on railway systems for safe and trusted transportation. An ideal public transportation system is one that can quickly stop or resume operations in response to sudden events such as earthquakes and heavy rainfall or snowfall. This research aims to establish suitable operating control techniques for extreme weather conditions, such as local heavy rainfall.

Development of recovery supporting methods linked to widespread hazards

When large-scale disasters occur, a decision must be made on which region should receive assistance in order to contribute to the recovery of society when road and railway infrastructures are damaged. This research studies 1) risk assessment methods following a disaster, and 2) recovery techniques during the early stages for optimum recovery.
