Earthquake Disaster Mitigation for Urban Transportation Systems: An Integrated Methodology that Builds on the Kobe and Northridge Experiences

9816193 Chang该项目是作为美国/日本城市地震减灾合作研究，美国/日本共同议程倡议。 该项目旨在通过美国/加拿大地震局的地震风险评估和城市交通基础设施系统的管理，日本研究合作。 该方法集成了工程，系统分析和经济学。 将开展三项相关任务：（1）制定性能标准和设计减灾战略，（2）模拟地震灾害中的交通和经济系统响应，以及（3）减灾战略的经济评估。 在任务1中，美国的作用将包括制定基于交通可达性措施的性能标准，与日本同行合作制定基于可靠性工程等替代标准，并设计相关的改造和维修策略，以用于运输经济模型的评估。 任务2的研究将集中在改进和扩大洛杉矶。高速公路模型 这项工作的重点是利用科比的经验数据对地震破坏修复和相关瓶颈进行建模，以评估更快的网络恢复的好处。 建模专业知识将与日本团队分享，因为他们为日本建立了类似的模型。 在任务3中，美国和日本的研究人员将合作评估改造和维修策略的效益和成本，并评估任务1中确定的性能标准的经济影响。 这是一个由华盛顿大学和南加州大学的研究人员联合开展的项目。 ***

9816193 Chang This project is funded as part of the U.S./Japan Cooperative Research in urban Earthquake Disaster Mitigation activity, a U.S./Japan Common Agenda initiative. The project aims to develop a cross-cutting methodology for seismic risk assessment and management of urban transportation infrastructure systems through U.S./Japan research collaboration. The approach integrates engineering, systems analysis and economics. Three related tasks will be carried out: (1) Development of performance criteria and design of mitigation strategies, (2) modeling transportation and economic system response in earthquake disasters, and (3) economic evaluation of mitigation strategies. In Task 1, the U.S. role will consist of developing performance criteria based on transportation accessibility measures, working with Japanese counterparts on alternative criteria based, for example, on reliability engineering, and designing associated retrofit and repair strategies for evaluation in the transportation-economic model. Research in Task 2 will focus on improving and expanding upon the L.A. Highways model. This effort will emphasize modeling of earthquake damage repair and associated bottlenecks using experience data from Kobe in order to evaluate the benefits of faster network recovery. Modeling expertise will be shared with the Japanese team as they build similar models for Japan. In Task 3, U.S. and Japanese researchers will collaborate on evaluating the benefits and costs of retrofit and repair strategies, and assessing the economic implications of the performance criteria identified in Task 1. This is a joint project carried out by investigators at the University of Washington and the University of Southern California. ***
