Landfills: Anatomy of Automated Design
California's 360 acre Bee Canyon landfill (completed last year) sits amid a complicated network of narrow canyons with side slopes 300 ft high. As with most landfill projects,...
The Roads Ahead
In 1990, 37 states spent almost $50 million on highway pavement crack sealing, according to researchers at the Strategic Highway Research Program (SHRP). In the near future, a robotic...
Life in the Fast Track
Through innovative financing and skillful construction management, Oklahoma is proving that transportation megaprojects are still possible, even during an economic downturn. The result...
A New Era In Transportation
Its passage into law was about as smooth as a rush-hour traffic jam, but the surprising thing about the new Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) is that it...
Mechanical Properties of High Performance Concretes
This paper presents some of the initial results of a 4-year research project on mechanical properties of high performance concretes with particular reference to highway applications. High...
Evaluating Damage Detection in Bridges
Several researchers have recently considered using vibration monitoring of highway bridges as a means for detecting structural deterioration. Results to date have demonstrated that the...
Building Lunar Roads?An Overview
Outposts and permanent installations on the moon will need a network of surface roads connecting them. The problem of creating such roads is more challenging than on Earth in most ways,...
Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...
Management of Design
Denver's new airport uses the services of over 80 separate design firms. The existing airport, Stapleton, could not be expanded to meet the forecasted demand of 1,200,000 operations with...
The Design of the Airside Concourses
The growth of commercial air traffic in the United States has resulted in the development of the 'New Denver International Airport.' the airside concourses were designed by joint venture...
Airport Landside Management: An Unique Airport Specialty
Air transportation has become a common and preferred method of travel, resulting in an ever increasing number of air passengers. The significant growth has resulted in unique and never...
The Airport Traffic Control Tower for the New Denver International Airport
Developing a new airport traffic control tower involves many complexities of planning, engineering, and coordination. For the ATCT at the New Denver International Airport, these complexities...
A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...
Analyzing Fast-Food Drive-Up Window Site Impacts
Peak-period queueing at a fast-food restaurant drive-up window was observed. The study found that queueing behavior equations based on random arrivals and service times overestimated the...
Trip Generation Rates, a Historical Look
This paper compares the 1990 weighted average trip generation rates of military bases, shopping malls, universities, airports, and hospitals for San Antonio-Bexar County and Amarillo,...
The Isolated Signalized Intersection as a Mitigation on a High-Speed Highway
A concentrated 'leap-frog' type development is commonly proposed as it offers the opportunity to organize an extensive living-recreation orientated site with low to modest land costs....
Access Management ? Myth or Reality
