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...
Controlled Braking on Uneven Roads
The braking process of a passenger car may be influenced by a large number of variables relating to driver, vehicle, brake system, tire-road interaction and ambient conditions. Because...
A Knowledge Based System with Uncertainty for the Soil
In this paper, we present the methodology that we used to develop the KBSOL Knowledge Based System for the soil. We describe the structure that contains the objects of the domain (layer,...
Reliability of Controlled Structures Subject to Real Parameter Uncertainties
This paper presents a systematic and probabilistically consistent approach for determining the likelihood that instability will result from the uncertainty inherently present in a controlled...
Effect of Active Control to Structural Reliability
Most available results in the study of structural reliability deal with idealized mathematical representation of structures. With model supported diagnosis of the structural condition...
A Two-Stage Safety Assessment Methodology for Construction Activities
The control of construction activities requires the evaluation of the condition of the control attributes of interest. In order to develop the required methodology, a model of the construction...
What Makes a Quality Paper?
A good paper is one that is easy for members of the intended audience to read and understand. It must contain an informative abstract. The introduction should include information on why...
Case Study: Design of Groundwater Quality Monitoring Systems
This paper demonstrates the fundamental aspects of the design an implementation of state-of-the-art groundwater monitoring system, using conventional design principles. Based on experiences...
Ecuador?The Lower Guayas Flood Control and Drainage Project?A Case Study
The Government of Ecuador (GOE) invited the World Bank in 1975 for a general review of the rural development in the country. One of the main findings of a Bank mission was the importance...
Operation of the Tennessee Valley Authority Water Control System Under Extreme Drought Conditions
The Tennessee Valley region recently suffered through the most severe drought of record. As increasing demands were placed on the reservoir system, operating priorities were modified to...
Expert System for Agricultural and Water Quality Management
Agricultural activities occur in an open environment where uncontrollable climatic events influence both agricultural productivity and water quality. A decision support system is described...
ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...
Modern Crane Control Enhancements
Terminal operators are continually looking for innovative ways to enhance the productivity and safety of their container cranes. This paper discusses examples of control enhancements that...
Perceptions, Sensitivity, and Solutions; Water Quality 2000
Commencing early in 1971, the Water Pollution Control Federation (WPCF) (now Water Environment Federation) established a series of challenge groups which would develop information essential...
Use of Interactive Simulation Environments for Evaluation of Water Supply Reliability
