Object Oriented Spacecraft Architecture
This paper describes an architecture for simplifying the spacecraft design and maintenance process: Object Oriented Spacecraft Architecture. Like object oriented programming, the strategy...

Using Simulation to Evaluate On-Orbit Construction Operations
As the NASA Space Exploration Initiative (SEI) program contemplates a permanent presence on both the Lunar and Martian soil, the necessity for On-Orbit Construction of the Earth-to-Lunar/Martian...

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...

Soft Touch People Mover Central Control
The people mover central control systems perform many automatic functions, are built with off-the-shelf redundant hardware, include advanced color graphics and touch screen operator interfaces,...

Impact of the New Denver Airport on the Air Traffic Control System
Building the new Denver Airport has two major impacts on air traffic control: first, it requires redesigning the airspace surrounding the Denver area; and second, it requires moving to...

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...

Comparison of Delay and ICU Analyses?Case Study
Traffic Management Initiative was a petition-based referendum that sought to limit traffic impacts of proposed or planned development through the use of more stringent transportation planning...

ICU?A Method of Analyzing Signalized Intersections
There is a need for decision makers, developers and the public to understand the potential traffic impacts of site development. Signalized intersection operations are a primary indicator...

Since 1976...

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,...

Estimation of Pass-By Trips Using a License Plate Survey
The objective of the study was to determine whether it is possible to estimate the percentage of pass-by trips using a license plate survey instead of the traditional interview survey....

Improvements on Quantifying Pass-By Trips for Shopping Centers
Improvements to the procedures for quantifying pass-by trips (T), handling imbalanced traffic volume conditions, and collecting field pass-by trip data are suggested. A simpler model which...
