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...
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...
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...
Developing Protocols for Motor Vehicle Air Quality Modeling
This paper is directed to air quality analysts. It examines the issues surrounding a modeling protocol and how to work effectively with a traffic engineer on a project to model carbon...
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...
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...
A Multiple Presence Load Model for Bridges
This paper utilises weigh-in-motion data to simulate multi-lane traffic crossing short span multiple-lane bridges. In this manner the reduction factors for a multiple lane bridge are derived....
