The Isolated Signalized Intersection as a Mitigation on a High-Speed Highway
A concentrated 'leap-frog' type development is commonly proposed as it offers the opportunity to organize an extensive living-recreation orientated site with low to modest land costs....
Housing Chernobyl Relocatees
The April 1986 explosion of the Chernobyl Nuclear Power Plant Reactor 4 in northern Ukraine Commonwealth spread nuclear contamination assisted by southerly winds across hundreds of miles...
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...
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....
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...
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...
Probabilistic Evaluation of Redundancy of Bridge Structures
Redundancy of bridge structures and methods to evaluate redundancy are reviewed in this paper. A method to measure redundancy based on the existing theories of probability as related to...
Pre-Envelope Covariance Differential Equations
The problem of predicting the safety of structural systems subjected to random loading arises in may engineering applications. In this framework the envelope process plays an important...
Structural Reliability and Proof Testing for Highway Bridges
This paper proposes a set of reliability-based proof load factors for highway bridge evaluation, to determine target proof load and load rating. The target safety index used is consistent...
Soil/Structure Seismic Investigation of Safety-Related Structures
This paper promotes an improved understanding of the type of earthquake motions felt at V.C. Summery, Perry and Krsko nuclear power plants. An analytical investigation is performed to...
A Systems Reliability Approach to the Safety of Steel Connections
A methodology is presented to determine the probability of failure of steel connections using a systems approach. Results indicate that connection safety evaluations which do not use this...
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...
Structural System Design under Uncertainty Via Pareto Optimization
Structural systems are generally designed under safety, serviceability and economy requirements. The single objective optimal design problem of both deterministic and nondeterministic...

Technology?Key to Environmental Success
A three million ton per year coal unloading terminal with 5 km overland conveyor at Jacksonville, Florida, incorporates numerous technical advances to achieve environmentally safe construction...
Application of Traffic Engineering Concepts to Pleasure Boat Traffic
The Los Angeles County Department of Beaches and Harbors initiated a study to investigate the feasibility of adding slips along the main channel in Marina del Rey in response to the surplus...
Design Criteria for Ferry Landings
This paper describes an ongoing research project conducted by the University of Washington Department of Civil Engineering to develop design criteria for the Washington State Ferry System....
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...
Replacement of a Deteriorated Steel Sheet Pile Bulkhead
This paper presents a life history of a marine steel sheet pile bulkhead, over 35 years old, that has been exposed to a salt water environment with minimal maintenance or repair in the...
Ship Simulation of the Houston Ship Channel, Houston, Texas
The Houston Ship Channel (HSC) consists of approximately 65 miles of improved deep-draft channels. The present channel is 400 ft wide and 40 ft deep at mean low tide for most of the channel...
