Validating Expert System Prototypes Using the Turing Test
This paper describes the Turing Test technique to formalize the expert system validation process using a mature microcomputer based prototype expert system that has been developed to perform...
Improving the Graphical Interface in Transportation Planning Software
This paper examines the general issues that drive the development of graphics as a medium for transportation planners. Transportation planning has changed over time, and so has the nature,...
Methodology for Determining Vehicle Usage and Speeds for Mobile Source Emissions Inventories
This paper was published by the Baltimore Regional Council of Governments to document its work in preparing data from its regional road model for input into a computer emissions inventory...
An Expert System for Stop-Controlled Intersection Design
In 1915, the first stop sign was installed in Detroit, Michigan, but until now, there was still no one coordinated body of knowledge which would dictate design and analysis requirements....
Tutorial on Computer-Aided Design
These tutorial sessions are designed to provide a basic introduction to the use of Computer-Aided Design/Drafting (CAD) in transportation engineering, with particular regard to Civil Engineering...
The Use of Linked Spreadsheets as a Transportation Problem Solving Tool
Spreadsheet modeling is a useful tool for business as well as engineering applications. Until the advent of linked spreadsheets this type of modeling was based on the concept of preparing...
A Peak Hour High Capacity Reservation and Person-Based Functional Classification Concept for Urban Mobility Plans and Corridor Growth Management
The management of future growth and mobility in urban corridors and areas has been based in part upon use of the Levels of Service and procedures of the Highway Capacity Manual. Capacity...
Technical Evaluations Necessary for Determining Site Suitability for a High-Level Waste Repository
Congress, under the Nuclear Waste Policy Act of 1982, as amended, has charged the Department of Energy with the responsibility for safely and permanently disposing of high-level radioactive...
Tectonic Characterization of a Potential High-Level Nuclear Waste Repository at Yucca Mountain, Nevada
Tectonic characterization of a potential high-level nuclear waste repository at Yucca Mountain, Nevada, is needed to assess seismic and possible volcanic hazards that could affect the...
Geometric Models of Faulting at Yucca Mountain
Yucca Mountain, Nevada, is currently being studied as a potential site for a geologic repository of high-level radioactive waste. Alternative conceptual tectonic models are expected to...
Preliminary Report: The Little Skull Mountain Earthquake, June 29, 1992
The Little Skull Mountain earthquake occurred about 20 km from the potential high level nuclear repository at Yucca Mountain. The magnitude was 5.6, and the focal mechanism indicates normal...
Current Plans to Characterize the Design Basis Ground Motion at the Yucca Mountain, Nevada Site
A site at Yucca Mountain Nevada is currently being studied to assess its suitability as a potential host site for the nation's first commercial high level waste repository. The DOE has...
Estimation of Near-Regional Seismic Ground Motion from Underground Nuclear Explosion Tests
A problem unique to the location of a nuclear waste repository adjacent to the Nevada Test Site is the assessment of seismic ground motion from potential underground nuclear explosion...
Optimal Cost Basis for Seismic Design
The paper summarizes a methodology for establishing seismic design levels based on a cost-benefit assessment. The methodology requires the development of costs and benefits for varying...
Geotechnical Instrumentation for Repository Shafts
The United States Congress passed the Nuclear Waste Policy Act in 1980, which required that three distinctly different geologic media be investigated as potential candidate sites for the...
Environmental Consulting Grows Up
The environmental engineering industry got its first taste of maturity in 1992, courtesy of the weak U.S. economy. Revenue growth, which had raced along at a 25%-30% clip for years, abruptly...
Engineering: Environmental vs. Developmental Goals
The 1992 winner of the Daniel W. Mead Student Paper competition explores the potential conflict for engineers, between environmental and developmental goals. Noting a dictionary definition...
Scoping Out Scour
Bridge scour�soil erosion around piers and pilings�threatens tens of thousands of bridges across the U.S. Traditionally, engineers have mapped bridge scour by driving probes into the subbottom...
Wind Engineering?Engineering for Wind Damage Mitigation
The establishment in 1970 of a new engineering discipline, wind engineering, was motivated by property damage caused by windstorms of 1970 known as the Lubbock Tornado and Hurricane Celia....
Seismic Performance and Retrofit of the Golden Gate Bridge
The Golden Gate Bridge has served for over fifty years as a vital transportation link connecting San Francisco with the area to the north. The Bridge is owned, operated, and maintained...
