The purpose of this research is to examine the accuracy of predicted ETMS airport and sector counts, and to attempt to develop better prediction algorithms. The remainder of this report is in six sections. Section 1 Quality of Current Predictions Discussion of the accuracy of current flight predictions for a given location and 15-minute time interval. Section 2 New Models for Predicting the Number of Flights The development and calibration of new models for predicting the number of flights in a 15-minute time interval. Section 3 Testing Model 2 Discussion of the testing of one promising new...

This report presents three case studies that illustrate how geographic information systems (GIS) have been used to implement the Federal Highway Administration's (FHWA) Planning and Environment Linkages (PEL) approach. The PEL approach provides information and tools to help agencies integrate consideration of environmental factors into transportation planning. PEL represents an approach to transportation decision-making that considers environmental, community, and economic goals early in the planning stage and carries them through project development, design, and construction. This can lead...

In this annual report, Traffic Safety Facts 1996: A Compilation of Motor Vehicle Crash Data from the Fatality Analysis Reporting System and the General Estimates Systems, the National Highway Traffic Safety administration (NHTSA) presents information from two data systems Fatality Analysis Reporting System (FARS) and National Automotive Sampling System/General Estimates System (GES)} to create a single source of motor vehicle crash statistics about traffic crashes of all severities, from those that result in property damage to those that result in the loss of human life.

This report provides the results of a survey of State highway agencies in the United States on partnering agreements with utility companies and whether any have agreements similar to the Australian MOUs. It also provides a step-by-step approach for developing an Australian-type MOU in the United States, a sample MOU template, and a sample conflict resolution matrix for handling differences that may arise.

In this annual report, Traffic Safety Facts 2008: A Compilation of Motor Vehicle Crash Data from the Fatality Analysis Reporting System and the General Estimates System, the National Highway Traffic Safety Administration (NHTSA) presents descriptive statistics about traffic crashes of all severities, from those that result in property damage to those that result in the loss of human life.

The United States possesses an effective and efficient surface transportation infrastructure that promotes both the well-being of its citizens as well as important economic and national security goals. The level of security afforded this infrastructure is relatively low compared to the security enhancements recently implemented in the commercial aviation sector. However, there is sufficient reason to believe that the security levels of the surface transportation modes need to be raised as the threat level increases and the vulnerabilities of the current infrastructure become apparent. There...

This report hypothesizes that the United States has reached a critical juncture in terms of national mobility trends and underlying socio-demographic conditions and travel behavior that will result in more moderate rates of annual vehicle miles of travel (VMT) growth in the future. However, slower VMT growth may not portend lower rates of congestion growth.

This document catalogs the symbols presented with the various interfaces used by Federal Aviation Administration Airway Facilities specialists. It includes a high-level overview of each system and the symbols and coding conventions used. These data were collected through analysis of software specifications, computer-based instruction manuals, and field site visits. The visits to field sites allowed verification of information from other sources and provided information about the environments that can affect the discrimination of visual symbols. Researchers used the information from the Human...

Electric Research & Management, Inc. (ERM) performed a survey to quantify the levels of extremely low frequency (ELF, 3-3000 Hz) electric and magnetic fields (EMF) and radio-frequency (RF, 300 kHz to 50 GHz) electric fields near electric facilities along Amtrak's Northeast Corridor (NEC) between New Haven, Connecticut, and Boston, Massachusetts. This work was sponsored by the Federal Railroad Administration (FRA) and contracted to ERM with oversight by the Volpe National Transportation Systems Center.

The Bureau of Transportation Statistics (BTS), a statistical agency within the Research and Innovative Technology Administration (RITA), U.S. Department of Transportation (DOT), compiles, analyzes, and publishes data and information needed for transportation decisionmaking, and generally coordinates DOT statistical programs. BTS also manages the National Transportation Library and the Office of Airline Information, and leads the federal effort in developing transportation geo-data to fulfill the vision of the National Spatial Data Infrastructure (NSDI).
