Effect of Earthquakes on Urban Highway Infrastructure Productivity

*** 9633386 Shinosuka最近的地震表明，一般来说，城市基础设施的故障，特别是公路系统的故障，会造成重大的经济损失。本项目采用多学科综合方法，结合土木工程、城市规划、经济学和公共政策方面的专业知识，考察地震对城市公路基础设施生产力的影响。重点将放在填补传统工程与社会经济和政策问题研究之间目前存在的差距。该项目的目标是开发一个综合框架和创新方法，从基础设施系统性能和生产力的角度评估城市地震风险和降低风险的经济后果。研究结果有助于优化提高城市公路交通基础设施在重大地震灾害下的生产力。虽然所开发的方法一般适用于城市地区，但在洛杉矶公路运输系统的情况下，原型设计工作将改进总体框架。原型将为评估将被嵌入其中的一般框架提供基础。此外，原型练习的框架和结果将指导南加州大学实验性民用基础设施课程的发展，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.***
