Risk Management for the Earthquake and Tsunami of the Hanshin Expressway

The 2011 Great East Japan Earthquake and followed tsunami devastated the coastal region of East Japan. Based on the experience of the large scale tsunami damage, road administrators in Japan are urgently preparing against another tsunami impact. Hanshin Expressway operates urban expressway network. Major part of the network runs through the Osaka bay area. Therefore the preparedness against tsunami inundation is one of the urgent challenges for Hanshin Expressway for quick recovery, even in the flooded condition. Currently, Hanshin Expressway finished the study on the countermeasures for tsunami inundation. The countermeasures consist of: 1) Development of a disaster countermeasure office that is safe from impact of the tsunami inundation, 2) Upgrade of maintenance and patrol base station that ensures functionality in case of a tsunami inundation, 3) Development of a self-powered supply system and redundant communication line, 4) Development of traffic control procedures for preventing casualties caused by the tsunami inundation, and 5) Development of the procedures for evacuation of the drivers on the expressway viaducts. This paper summarizes the key points of those countermeasures.
