Probabilistic Design of Flexible Pavements
Numerous random phenomena enter into the process of deterioration of pavements under the effect of traffic. It is felt that improvement in current design methods could be obtained by adopting...
Analysis of Bridge Truck Loads
The development of the reliability-based load and resistance factor design (LRFD) methodology requires uncertainties in loads and resistance be quantified. In the load capacity evaluation...
Damage Accumulation Models for Bridges
In the study summarized in this paper the serviceability and ultimate limit states were reviewed for concrete and steel girder bridges. A model is proposed to evaluate strength and remaining...
Rehabilitation of Highway Bridges: Design and Operational Considerations
The design of a rehabilitation of a bridge which must maintain some lanes of traffic requires special consideration of construction procedures and traffic control, which are discussed...
Fatigue Reliability of Ship Hull Girder
Based on estimates on uncertainties in wave loading and fatigue capacity the fatigue reliability of ship hull girder is calculated with respect to global vertical wave bending moment....
Time Variant Reliability Analysis Using Bivariate Diffusive Crack Growth Models
This paper is concerned with the development of a time-dependent reliability concept. The time variant load carrying capacity, i.e., resistance, of a structure caused by fatigue is expressed...
An Investigation into Causes of Bank Caving
A series of investigations into bank caving along the Ohio River are described. These investigations include a study of the distribution of precipitation in the study region, derivation...
Traffic Jams on Main Street
Traffic congestion in suburban areas has become a leading public concern prompting a renewed search for transportation and land use strategies to help relieve congestion. Causes of traffic...
Accommodation of Trucks on the Highway
Safety in Design
This book contains the papers presented at the symposium on accommodation of trucks on highways held in Nashville, Tenn., May 11, 1988. The papers address highway factors that contribute...
Measurement and Analysis of Tracfcfifc-Induced Transient Motion in Navigation Channels
Two-induced physical effects related to navigation changes on the Kanawha River, West Virginia were measured at three environmentally sensitive representative locations. The purpose of...
Highway Safety - Is the Job Finished?
A review of past measures undertaken to improve highway safety is given. The Highway Safety Acts have helped reduce the number of injuries and fatalities in spite of the increased number...
Historical Changes in Highway Safety: 1966 - 1987
During the past several decades, substantial changes have occurred in the national economy and culture. Corresponding changes have taken place in the highway transportation system. While...
Current Status of Research and Implementation
A review of the effectiveness of roadway safety measures to reduce traffic accidents is given. This paper attempts to discuss in detail the current status of safety-related knowledge and...
Changing Requirements
There are three sections to the presentation. First, a discussion of the changing environment of highway transportation - what are the factors and variables that are changing in the world...
Highway Injuries: Our Major Health Problem
Injuries are the leading cause of death in the United States from early childhood until about age 45. Motor vehicles kill more Americans age 1 to 34 than any other source of injury or...
Environmental Health Programs of the USEPA
The major programs of the U.S. Environmental Protection Agency (EPA) designed to reduce risk to public health are summarized with emphasis on their content, funding and effectiveness in...
Air Safety?Programs and their Effectiveness
Airplane accidents have always had considerable media attention, particularly, when they involve large numbers of fatalities. Ever since the Airline Deregulation Act of 1978 and the air...
Railroad Safety Programs and Effectiveness
Safety in the railroad industry has been a matter of concern to employees, officers, federal agencies and the general public since railroads came into being. This paper summarizes the...
Conflicts: The Common Denominator of Health/Safety Programs
Constraints on time and resources influences the public sector as strongly as our personal lives. Experience teaches us that our desires must be tempered with hard realities. Finite resources...
Allocating Public Funds: Morality and Constraints
The highway safety engineer is continually faced with the trade-off between expenditures for highway safety improvements and reductions in highway fatalities, injuries, and property damage...
