Software Utilities for Traffic Simulation Models
Simulation models of traffic flow on highways are increasingly becoming the choice of many analysts and traffic engineers as analytical tools to test, evaluate and implement traffic control/management...
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,...
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...
Factors Controlling Strong Ground Motion and Their Associated Uncertainties
Of special interest in strong ground motion modeling is a quantification of the degree of influence specific physical parameters have on the computed motions. Associated with the model...
ASTM C666 (A) Freeze-Thaw Durability of Air-Entrained Wet- and Dry-Mix Shotcrete
In order to assess the freeze-thaw durability of shotcrete, six samples of dry-mix shotcrete and one sample of wet-mix shotcrete were mixed outdoors at Hydro-Quebec's research institute...
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....
Earthquake Resistant Design and Construction of Reinforced Concrete Buildings. The Practice in Mexico After 1985
The evolution of the design and construction practice of reinforced concrete buildings in Mexico is presented in terms of materials, structural systems, member design and reinforcement...
CenterCore Strengthening System for Seismic Hazard Reduction of Unreinforced Masonry Bearing Wall Buildings
The CenterCore technique of reinforcing unreinforced masonry walls was developed with the help of a National Science Foundation grant in 1984. The CenterCore strengthening system consists...
Seismic Analysis of Meloland Road Overcrossing Using Calibrated Structural and Foundation Models
A detailed seismic analysis of the Meloland Road Overcrossing is being implemented to study the response of this bridge during the 1979 Imperial Valley Earthquake. This analysis is based...
Fire Retardant Treated Wood
The paper explains how FRTW chemicals react with combustible gases. It describes the two types into which FRTW is divided. Misconceptions about FRTW are also addressed....
Wind Design and Analysis for the Normandy Bridge
The Normandy Bridge will represent an important progress in the field of cable-stayed bridges, with a main span 856-metre long. This paper explains how the design has been oriented to...
Wind Tunnel Testing for the Great Belt East Suspension Bridge
This paper provides an overview of model tests conducted to study and predict the aerodynamic behavior of the proposed streamlined box-girder suspension bridge for the Great Belt Link....
