Effectiveness of Implemented HOV Lane System
Individual carpool lanes have proven their worth on a case by case basis. Now, in California and across the country, systems of HOV lanes are being planned for urban areas dealing with...

Travel Markets: An Approach to TCM Effectiveness Evaluation
This discussion paper describes a new approach to TCM evaluation using a travel market concept to classify trip types based on expected elasticities to various TCMs. Conventional trip...

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...

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...

The General Theory of Quantitative Risk Assessment
From the many individual applications of quantitative risk assessment (QRA) that have been made in various fields, this paper abstracts and lifts out the concise, simple, and elegant cluster...

Risk Assessment or Engineering Standards: Toward a Decision Framework
The Army Corps of Engineers (ACE) publishes manuals, some of which include rules to be followed in the planning of a water resources project. Some of their other manuals simply suggest...

Climatic Change and Ensuing Risks Facing Water Resources Managers
Global climatic changes will have a significant effect on the utilization of regional water resources and will influence markedly the operation and management of water storage and delivery...

Responding to Public Opinion About Cumulative Long-Term Risks: Analysis and Communication of Risks from Climate Change and Hazardous Waste Sites
Public reactions to cumulative, uncertain, and long-term (CULT) risks pose particular problems to risk communicators. Low-magnitude and low-probability risks (e.g., living next to a hazardous...

Integrated Assessment of Environmental Risk and Human Response
Meaningful risk assessment for environmental problems requires an integrated consideration of physical science and human behavioral issues. This is particularly true when dissaggregate...

Quantitative Risk Assessment and Technology Transfer: Software Developments
A risk-based adaptation of the hydroeconomic model for estimating the expected annual damages of floods is presented in a spreadsheet environment. The model demonstrates how commercially...

The Monitoring of Water Conservation Behavior and Attitudes in Southern California
Seldom are the effects of public information programs monitored and analyzed in a sound, systematic manner. Information on the impact of investments in public information programs is essential:...

Conflicts in Health and Safety Matters: Between a Rock and a Hard Place
Constraints on time and resources influence the public sector as strongly as they influence our personal lives. Experience teaches us that our desires must be tempered by hard realities....

Moving Toward a Probability-Based Risk Analysis of the Benefits and Costs of Major Rehabilitation Projects
By the year 2010, 77% of the U.S. Army Corps of Engineer's projects will be over 40 years old. The Corps wants to allocate its scarce rehabilitation funds in a cost-effective manner. To...

An Innovative Institutional Arrangement Which Incorporates the Risk Preferences of Water Users
An innovative institutional arrangement that incorporates the risk preferences of water users is being refined in Australia. It is especially relevant for river and reservoir management...

Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...

On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....

Methodology for Evaluating Dredged Material Alternatives Using Risk-Cost Analysis Under Uncertainty
A methodology and a case example was presented at the 1989 Conference on Risk-Based Decision Making in Water Resources, Santa Barbara, to perform risk-cost analysis for dredged material...

Maximum and Minimum Storage Trajectories That Meet Specific Risk Levels
One of Hydro-Quebec concerns is to operate its installations so as to satisfy the operating constraints. This paper describes a mathematical tool that enables the utility company to state...

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...
