Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...
Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...
OSHA and the Design Professional
Since the creation of the Occupational Safety and Health Administration, the question of how the role of design professionals - engineers and architects - relate to the safety of a construction...
Road to Recovery
The effect of the Loma Prieta earthquake on San Francisco's elevated viaduct system is still being felt more than four years later. Immediately after the quake, the entire...
A New Angle on Ground-Water Remediation
When engineers from Black & Veatch Waste Science (BVWS) went to Tinker Air Force Base to examine the site of a hazardous waste cleanup job the service had hired them for, they...
A League of Their Own
New baseball stadiums in Cleveland and Arlington, Tex., opening in April 1994, combine the nostalgia of traditional ballparks with state-of-the-art site planning and structural engineering....
Microsurfacing Urban Pavements
A European maintenance technique called microsurfacing can add years to the service life of cracked, ravelled pavements--with minimal interruption to traffic and for less than half the...
SCHEREC: SCHedule RECovery System
Creating a revised plan requires experience and significant time. To lessen the effort involved, a knowledge-based system named SCHEREC (SCHedule RECovery) was developed which suggests...
Interpretive and Modelling Problems of Risk and Uncertainty in Bidding Techniques
This paper considers the implementation of policy, strategic and tactical bidding and the processes of devolution of the risk and uncertainty in a corporate management context....
Decision-Making Paradigm for Risk Assessment of Hazardous Wastes Using Fuzzy Sets
This paper summarizes the development of a risk assessment framework to provide risk-cost policy alternatives to prioritize remediation actions for hazardous wastes. The framework is a...
Development of an Expert System to Identify Hazardous Highway Spots
The paper describes the development of an expert system within a geographic information system to identify high-hazard spots in a highway network. The philosophy guiding expert system...
The Safety Advisor: An Interactive Object-Oriented Program for Assessing the Safeness of Roadway and Roadside Designs
This paper describes an object-oriented software tool for performing safety assessments of roadway designs. Safety assessments are used to estimate the effect of changes in roadway characteristics...
Calibration of a Highway Traffic Assignment Model for the Manhattan Central Business District
This paper describes the application of a traffic assignment model, specifically the TRANPLAN model, in New York City together with the methodologies and the satellite programs that were...
A Speed Prediction Model for New Zealand Highways
This paper outlines a limiting speed model using probabilistic techniques to simulate the different types of vehicles and their performance along a two-lane rural highway. The road to...
Automated Design of 3-D Highway Sign Bridge Structures
A PC-based computer analysis/design program for 3-D Sign Bridge Structures including Pre- and Post-processor has been developed. The analysis of thirty different types of sign support...
GIS Modeling of Neo-Traditional Neighborhood Development
Emerging strategies for land use development suggest that neo-traditional neighborhoods promote increased accessibility with reduced traffic congestion compared to current suburban developments....
Implementation of Knowledge-Based GIS: A Case Study
This paper describes work almost complete at North Carolina A&T State University, whose primary purpose was to use the increased capabilities offered by geographic information...
Integrating Computer Applications for Traffic Data Analysis
Transportation and traffic engineers have traditionally used a variety of software packages and data sources to comprehensively evaluate traffic operations and establish project priorities....
Studying Route Choice Behavior Using Computer-Aided Telephone Interviews and GIS
In this paper two innovative techniques in developing route choice surveys are introduced. The first is using computer-aided telephone interviews (CATI), and the second utilizes geographic...
