Antarctic aviation has been evolving for the best part of a century, with regular air operations developing over the past three or four decades. Antarctica is the last continent where aviation still depends almost entirely on expeditionary airfields and ?bush flying,? but change seems imminent. This report describes the history of aviation in Antar

Previous research has shown that the presence of head-up display (HUD) symbologycontaining altitude information improves altitude performance at the cost ofterrain path performance, implying that these information sources may not beavailable for concurrent cognitive processing. In two flight simulationexperiments, the influence of attentive field s

Various types of paint schemes on aircraft propeller and rotor blades are used to improve the visual conspicuity and attention-getting value of those blades when they are rotating. The improved conspicuity resulting from the paint schemes has the purpose of reducing the number of injuries and fatalities that might occur due to accidental contact wi

The research report is the fifth year continuation of a six year research effort focused on quantifying urban mobility. The study contains the facility information for 50 urban areas throughout the country. The database used for this research contains vehicle-miles of travel, urban area information, and facility mileage data from 1982 to 1990. Vari

The main objective of the present study is to analyze roadside inspection data and its relationship to safety/compliance review and accident data. Data used for this analysis is provided by the Office of Motor Carriers and includes a sample of larger carriers with the most recent inspection information and safety ratings. As part of this paper, sum

The various sources and consequences of damage to epoxy-coated reinforcement were studied. For inspection of damage before placement, holiday detectors were evaluated. Potential damage, resulting from concreting operations such as placement and consolidation, was investigated. To examine the quality of the coating following application, a hot water

The Automated Road Inventory (ARI) is a software application used to automate the generation of Roadway Inventory (RI-1) diagrams. The RI-1 diagrams, which are hand drawn visual roadway records created by the Division of Transportation Planning of the Texas Department of Transportation (TxDOT), depict all highways maintained by the Department. ARI

This report outlines the research and recommendations concerning the rehabilitation of IH-10 through the downtown area of El Paso. The project of isolating an appropriate rehabilitation method was broken into three tasks. Task 1 included collecting background information such as traffic data and environmental information, documenting current paveme

QUEWZ-92 is a microcomputer analysis tool for planning and scheduling use in freeway work zone lane closures. It analyzes traffic conditions on a freeway segment with and without a lane closure in place and provides estimates of the additional road user costs and of the queuing resulting from a work zone lane closure. The road user costs calculated

The main objective of this study is to investigate the importance of depth to bedrock in surface loading tests. Two surface loading tests, the Dynaflect and Falling Weight Deflectometer (FWD), were investigated analytically using four typical in-service Texas highway pavement profiles. The dynamic effect of these surface loading tests was in terms

Recently, a new and larger seven-wire strand was offered by industry for use in pretensioned concrete. The new strand size, 0.6 inches in diameter, has 40 percent greater area and 40 percent greater capacity than the current industry standard, 0.5-inch-diameter strand. Larger strand sizes can lead to improved efficiency of pretensioned structures;

Over the past 40 years, the application of automation to the U.S. air traffic control (ATC) system has grown enormously to meet significant increases in air traffic volume. The next ten years will witness a dramatic overhaul of computer hardware and software in enroute and terminal facilities to accommodate future growth in air traffic activities.
