Opportunities for Improved Transportation Planning
The approaches, technical procedures, and analytical methodologies utilized for urban transportation planning need to be improved if the intent of the 1990 amendments to the Clean Air...
Delaware Valley Regional Planning Commission's Anticipated Response to the Clean Air Act Amendments of 1990
By virtue of its charter to provide continuing, cooperative and comprehensive planning, the Delaware Valley Regional Planning Commission (DVRPC) has a commitment to adopt and maintain...
San Francisco Bay Area's Experience Developing Transportation Control Measures for Air Quality Plans
The San Francisco Bay Area has included Transportation Control Measures (TCMs) in air quality planning efforts since the early 1970s. Growing concern for traffic congestion has enhanced...
The Clean Air Act: Opportunities for the Transit Industry
The 1990 Federal Clean Air Act Amendments (CAAA) have opened up new opportunities for transit agencies, especially those in large urban areas with the worst air pollution problems. The...
GIS for Transportation and Air Quality Analysis
Geographic Information Systems (GIS) promise significant potential to manage complex spatial data often required to address transportation and air quality analysis problems. However, this...
Evaluating the Effectiveness of Transportation Control Measures for San Luis Obispo County, California
The San Luis Obispo Air Pollution Control District has developed simple techniques to estimate emission reductions from various Transportation Control Measures. Accurate emission estimates...
In-Use Emissions with Today's Closed-Loop Systems
Closed-loop emission control systems were adopted by most motor vehicle manufacturers on a wide-spread basis in model year 1981, in order to meet the 1981 and later Federal exhaust emission...
Integrating Traffic and Air Quality Modeling Techniques to Predict Pollutant Concentrations Near Intersections
Many cities are considering transportation management measures and/or tailpipe emission controls to reduce the pollution associated with traffic congestion. A major difficulty is the expensive...
Risk Analysis in Water Resources Engineering: Development and Application
Traditional engineering approaches for evaluating safety and performance in technical projects are usually based on conceptual modeling and the application of engineering standards. Risk...
System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...
Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...
Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....
Reliability Analysis of Lunar Structures Under Meteoroid Impact
The United States is slowly moving towards lunar base, and possibly Mars base, activities. Design of structures for these bases requires knowledge about loadings and conditions which in...
Probabilistic Analysis of Post-Tensioned Steel Girder Bridges
External post-tensioning is used as a means of strengthening existing steel girder bridges. Since absolute safety of structures is impossible to attain due to uncertainty in load and resistance,...
Fuzzy Measures in the Knowledge Based Diagnosis of Seismic Vulnerability of Masonry Buildings
Rules based expert systems and fuzzy logic have been employed to increase the speed and the reliability of the survey of masonry buildings, to forecast their seismic vulnerability....
Application of the Sampling Theorem to the Representation of Random Fields
A new parametric model is developed for homogeneous Gaussian random fields based on a generalization of the sampling theorem. The model depends linearly on a finite set of discrete values...
Response Variability and Reliability of Plates Using the Weighted Integral Method
A methodology is introduced to perform both the response variability and reliability analysis of two-dimensional stochastic systems (specifically plates subjected to plane stress or plane...
Stochastic Finite Elements and Reliability Analysis
A general - purpose approach for assessing the reliability of a nonlinear mechanical system under stochastic conditions was presented in (Faravelli, 1991). It combines the skeleton of...
Stochastic Dynamics of Hysteretic Systems
A frequency domain method is discussed in order to evaluate the second order statistical response of nonlinear hysteretic structures. Both shear type systems and lumped mass frames involving...
Structural Reliability of Seismic Isolation System
