RRR Design Standards: Cost-Effectiveness Issues
The Transportation Research Board study of geometric design standards for RRR projects is currently trying to match the logic of cost-effectiveness to the mostly judgmental process of...
Delineation Effectiveness for Alcohol Involved Accidents
The approach to the problem of the alcohol impaired drivers to date has been directed at driver education and increased police enforcement. A complementary and parallel approach is presented...
Sighting Safety
This paper examines the interrelation between drivers' visual needs and the road environment. Specific elements of visual limitation and drivers at greatest risk are identified....
An Analysis of Traffic Signal Safety Improvements
Identifying high accident rate locations and determining that they have an overrepresented type or pattern of accidents is an important first step in the safety improvement process. However,...
Location and Development of Safety Projects
Projects to be considered for inclusion in the Highway Safety Improvement Program (HSIP) must be part of a prioritized listing in which each project is based on accident experience or...
Evaluation?A Key to Safer Design Standards
Public highways are designed and constructed in accordance with established standards which have been developed over the years as a result of research studies or developed by committees...
Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...
New Techniques in Forced Vibration Testing
Forced vibration testing is a well established technique as indicated by references 1 to 8. This paper describes a system for forced vibration testing developed over two years during work...
Design and Planned Use of a 2-Kiloton Eccentric Mass Vibrator
High-level testing of large civil structures is usually not practical, due to structural damage considerations and available testing equipment. However, in the case of a joint American/German...
Frequency Domain Analysis of a Tank-Soil System
The dynamic response of an elastic cylindrical tank supported on a rigid base under a harmonic vertical excitation is analyzed taking into consideration its interaction with the foundation...
A Salt Solution for Nuclear Wastes
The Department of Energy's Waste Isolation Pilot Plant in Southeastern New Mexico is the nation's first full-scale facility for disposing of radioactive waste...
Overcoming Opposition
During a zone change hearing in connection with site selection for a new landfill near Coeur d'Alene, Idaho, some honest communication overcame opposition by the residents....
Back on a Full Speed Track
A $30 million rehabilitation project is transforming a Massachusetts rail line that shows its age and poor maintenance history. Rehabilitating the line from Bristol County, Mass. to Hyannis...
Clean-up in the Rockies
The shallow aquifer flowing beneath the Rocky Mountain Arsenal, just outside of Denver, has become contaminated with a number of toxic substances. Until the arsenal can be cleaned-up,...
The Asbestos Impasse
Removing asbestos from the nation's buildings is a major task . Consulting engineers can play an important part in the process, locating and quantifying the carcinogenic material,...
Cleaning Up Toxics
Case histories show how several different types of contamination cleanup were handled. In Attleboro, Mass., washwater, used to decontaminate equipment and tools after cyanide was removed...
Fire on the Water
Incineration is a promising hazardous waste disposal technique. However, nobody wants an incinerator constructed near him, so waste handlers are considering burning hazardous wastes at...
Treatment in Your Own Backyard
Everyone wants the nation's hazardous waste sites cleaned up, but nobody wants the wastes disposed of near them. Therefore, cleaning up these problems at the site may be the...
Attapulgite: A Clay Liner Solution?
Poor performance of clay liners at waste management facilities has resulted in the EPA mandate of synthetic polymeric liner materials to comply with zero penetration requirements. Laboratory...
Risk Assessment: Engineering Tool
In factoring in human-health impacts when tackling an environmental problem, risk assessment is often the best approach. Its use is growing fast. The technique increasingly is being used...
