Approximately 80% of general aviation accidents in the past decade have been tributed to errors made by pilots. For this reason, the most promising approach to making substantial improvements in general aviation safety is through the systematic study of factors affecting the performance of general aviation pilots (i.e., human factors) and use of th

Air Carrier Financial Statistics (Yellow Book)
|
PDF
Air Carrier Financial Statistics (also known as the Yellow Book) was a quarterly report of airline statistics compiled by the Civil Aeronautics Board. The data presented was of two kinds: (a) basic figures taken directly from air carrier reports on CAB Form 41 and (b) derived figures calculated from the basic figures (totals, averages, percentages,

Some Indiana road sections designed and built in the past do not meet the current design standards. INDOT makes a continuous effort to modernize these sections. Due to prohibitive costs, reduced design speeds and design exceptions are considered. Guidance is needed to help reduce the discrepancy between the economically justifiable design solutions

The mission objective of the Automatic Traffic Advisory and Resolution Service (ATARS) is to increase civil aviation safety by reducing the potential for mid-air collisions and near-miss encounters that can result from:a. Aircraft deviations from assigned altitudes and/or routes due to pilot error or equipment malfunction.b. Air traffic control (AT

In recent years, context-sensitive highway design has been promoted to ensure that designers consider the environmental, scenic, aesthetic, historic, community, and preservation aspects of the road. Context-sensitive design may lead to situations where the current design standards cannot be met because of restricting local conditions. Indiana has r

Waste plastic (WP) is a growing environmental concern due to its non-biodegradable nature, large-scale production, and harmful impact on natural resources. With nearly 75% of WP in the U.S. ending up in landfills, effective recycling strategies are urgently needed. In parallel, the limited availability of natural aggregates highlights the need for

The Microwave Landing System (MLS) Basic-Wide System at Wallops Island, Virginia, will be evaluated to determine the operational subsystem and system mean times between failures (MTBF) and mean times to repair (MTTR). Failure rates will be calculated. The calculated values will be compared with the contractor's predicted values. Reliability and mai

The Nebraska Department of Transportation (NDOT) must manage sediment, and pollutant loads from roadway runoff to meet stormwater regulations. The SAFL Baffle, a hydrodynamic separator used by NDOT, depends on reliable estimates of total suspended solids (TSS) and particle size distribution (PSD). However, limited data exists for Nebraska roadways.

The primary objectives of testing the Moving Target Detector (MTD) and the Radar Data Acquisition Subsystem (RDAS) as an integral part of the Discrete Address Beacon System (DABS) are to characterize their combined performance in:a. Providing radar/beacon correlation of DABS and Air Traffic Control Radar Beacon System (ATCRJSS) targets with radar t

The primary purpose of these tests is to determine the performance of the aircraft control state (ACS) function in an en route environment. This function has been incorporated in the en route Discrete Address Beacon System/Air Traffic Control (DABS/ATC) Build II software system. It allows the en route DABS/ATC Build II system to perform primary/sec

Results of a math model study for the runway 16R instrument landing system, (ILS) localizer at the Seattle-Tacoma Airport, Washington, are presented. This study was performed at the request of the Northwest Region of the Federal Aviation Administration (FAA) to determine the effects to the course structure of a proposed building and the replacement

An evaluation of the Active Beacon Collision Avoidance System (BCAS), Automated Traffic Advisory and Resolution Service (ATARS), and the Conflict Indicator Register (CIR) interface logic was conducted at the Federal Aviation Administration Technical Center. The evaluation was performed using dynamic simulation. The test bed for the evaluation was t

The integration of truck platooning and electrification presents a promising avenue for improving operational efficiency and environmental sustainability in freight transportation. Realizing the energy and cost saving as well as emission reduction benefits requires a holistic design of truck routing, scheduling, and platooning strategies that accou

Traditionally, crash data, crash risk models, video recordings and user surveys have been utilized by agencies to measure the safety benefits of ramp metering technology. Connected vehicle data can now provide an agile evaluation alternative for quantifying impact of ramp meter deployments. Furthermore, in contrast to crash data, connected vehicle

Hard-braking and hard-acceleration data have been demonstrated as an important emerging data source that provides quicker feedback than crash data. In fact, a strong correlation between hard braking on the interstate and crash rates has been reported in previous studies. A previous study has shown that there are approximately 147 hard braking event

Throughout the state of Indiana, there a number of older, historical bridges which have been in service since the late 19th century. Many, although not all, of these bridges are truss structures comprised either partially or completely of wrought iron members. Moreover, most of them need some degree pf maintenance or rehabilitation. However, engine

Trucks represent the predominant form of domestic freight movement. Due to the substantial increase in freight truck traffic on the nation’s highways, its influence on traffic flow performance, safety, and quality of travel experience, is garnering increased attention. Several existing studies have addressed the impacts of trucks on highway traffic
...
The INDOT Long-Range Planning Section has developed a set of planning tools that will support the system-level analysis of the state transportation system. These tools are employed to monitor transportation system performance, identify highway needs, and provide a quantitative analysis of the impacts of transportation improvement projects. The tool

In this study, a fuzzy logic-based modeling framework is proposed to capture car-truck interactions from a non-truck driver perspective using measurable variables. This is done by introducing the notion of “discomfort” in the vicinity of trucks and using it to extend existing microscopic traffic flow modeling logic. A new parameter called driver di
