An Effective Integrated Approach to the Operational Efficiency, Structural Preservation and Security of Transportation and Other Infrastructure Systems

چکیده
The importance of our infrastructure systems as the foundations for our civilization, maintaining the health of our society and serving as the engines for our economy has been articulated by the NSF and other government agencies since the 1970’s. The National Earthquake Hazards Reduction Program (NEHRP), created by the US Congress by the Earthquake Hazards Reduction Act of 1977 was based on recognizing the impacts of earthquakes on infrastructures, and was instrumental for significant advances in earthquake engineering. Problem-focused research by engineers and scientists on earthquake disaster mitigation brought to us considerable advances in the understanding of how geotechnical and constructed systems are affected by and respond to earthquakes. New design and retrofit methods were found, various mitigation strategies were developed, and these were codified and implemented.

Land use planning is the main core of urban planning and one of the main components of an urban system. This element has close relation with transportation system of the city, so if their interaction becomes insufficient, deterioration and chaos would have an adverse impact on the urban system and would cause serious environmental issues. The integrated land use-transportation models seem to b...
