This report presents finding from the National Survey of Bicyclist and Pedestrian Attitudes and Behavior, jointly sponsored by the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) and the Bureau of Transportation Statistics (BTS) and administered by The Gallup Organization. The goals of the survey were to ascertain the scope and magnitude of bicycle and pedestrian activity and the public’s behavior and attitudes regarding bicycling and walking. This report, Volume I: Summary Report, provides a top line summary of key data results regarding the behaviors and attitudes on various topics related to walking and bicycling including reported frequency of walking and bicycling during the summer months, trip purpose and characteristics, perceptions of safety, safety practices, facilities available and community design.

Volume II: Findings Report presents a detailed analysis on these topics. This report, Volume III: Methods Report describes the methods used to conduct the interviews and analyze the data.  It also contains a copy of the questionnaire.  The data come from a survey conducted among a representative sample of 9,616 U.S. residents age 16 and older during the Summer of 2002.

This report presents the methodology and results of the independent evaluation of a prototype integrated crash warning system for light vehicles as part of the Integrated Vehicle-Based Safety Systems initiative of the United States Department of Transportation’s Intelligent Transportation System program. The system integrates rear-end crash, curve-speed warning, lane change crash, and lane departure warning functions. The goals of the independent evaluation are to assess the safety impact, gauge driver acceptance, and characterize the capability of the integrated safety system. The evaluation is based on naturalistic driving data collected from a field operational test using 108 subjects who drove 16 passenger vehicles equipped with a prototype integrated safety system and a data acquisition system. The test subjects accumulated over 213,000 miles during a 12-month period throughout parts of southeast Michigan. For each driver, the test period was divided into a 12 day baseline condition with the system disabled and a 28 day treatment condition with the system enabled to compare the effect of the system on driving performance. The results of the analysis suggest that driving with the integrated safety system improves driver behavior and increases driver safety, that drivers feel that the system provides a safety benefit, and that the system alerts had a high degree of accuracy. This report delineates the methodology of the different analyses and discusses their results.

This report presents results from the independent evaluation of a field operational test using a fleet of heavy trucks outfitted with a prototype integrated crash warning system. This effort was conducted as part of the U.S. DOT’s Integrated Vehicle-Based Safety Systems (IVBSS) program. The system tested included rear-end, lane-change/merge, and lane departure crash warning functions. The goals of the evaluation were to assess safety impact and driver acceptance, and to characterize the prototype system’s warning capabilities. Eighteen volunteer drivers from a commercial fleet operated the 10 equipped heavy trucks, accumulating 600,000 miles over a 10-month period. The test period consisted of 2 months of baseline driving, when the system was disabled, and an 8-month treatment period, when the system was enabled and warnings were presented to the drivers. Comparisons were made between baseline driving and the treatment period to determine the effect of system use on driver behavior and performance.
