Effect of Earthquakes on Urban Highway Infrastructure Productivity

*9633386新宿最近的地震表明，城市基础设施的总体故障，特别是高速公路系统的故障，可能会造成重大的经济损失。该项目利用多学科综合方法，结合土木工程、城市规划、经济和公共政策方面的专业知识，研究地震对城市公路基础设施生产率的影响。重点将放在填补传统工程学与社会经济和政策问题研究之间目前存在的差距上。该项目的目标是从基础设施系统性能和生产力的角度，制定一个综合框架和创新方法，以评估城市地震风险和减少风险的经济后果。研究结果有助于以最佳方式提高面临重大地震灾害的城市公路交通基础设施的生产率这一长期目标。虽然所制定的方法将普遍适用于城市地区，但原型工作将完善洛杉矶公路运输系统的总体框架。原型将为评估它将嵌入其中的一般框架提供基础。此外，原型工作的框架和结果将指导南加州大学开发实验性的民用基础设施课程，旨在作为多学科教育和学生培训的典范。

*** 9633386 Shinosuka Recent earthquakes have demonstrated that urban infrastructure failures in general and highway systems failures in particular can cause significant economic loss. This project examines the effect of earthquakes on urban highway infrastructure productivity by making use of a multidisciplinary and integrative approach, combining expertise in civil engineering, urban planning, economics, and public policy. Emphasis will be placed on filling the gap that currently exists between traditional engineering and socio-economic and policy issues studies. The objective of this project is to develop an integrated framework and innovative methodologies for evaluating the economic consequences of urban seismic risk and risk reduction from the perspective of infrastructure systems performance and productivity. The results can contribute to the long-term goal of optimally enhancing the productivity of urban highway transportation infrastructure exposed to significant seismic hazard. While the methodologies developed will be applicable to urban areas in general, a prototyping exercise will refine the general framework in the case of highway transportation systems in Los Angeles. The prototype will provide a foundation for evaluating the general framework in which it will be embedded. In addition, the framework and results from the prototyping exercise will guide the development of experimental civil infrastructure curricula at the University of Southern California intended to serve as a model for multidisciplinary education and training of students.***
