The research was conducted by the Office of System and Economic and Assessment at the Volpe National Transportation Systems Center, Research and Special Programs Administration, U.S. Department of Transportation under the sponsorship of the Office of Mobility Innovation, Federal Transit Administration, U.S. Department of Transportation and funded by the Intelligent Transportation Systems Joint Program Office, Federal Highway Administration, U.S. Department of Transportation.

The National Highway Traffic Safety Administration (NHTSA) Office of Vehicle Safety Research, in conjunction with the Research and Special Programs Administration Volpe National Transportation Systems Center (Volpe Center), is conducting separate analyses of major vehicular crashes in support of the Intelligent Vehicle Initiative (IVI). The IVI is focused on solving traffic safety problems through development and deployment of vehicle-based and vehicle-infrastructure cooperative countermeasure systems that address rear-end, roadway departure, lane change, crossing paths, driver impairment,...

The Houston Smart Commuter Intelligent Transportation Systems operational test spanned almost ten years from the original feasibility study beginning in 1990 to the conclusion of the test period in 1999.

The National Highway Traffic Safety Administration (NHTSA), in conjunction with the Research and Special Programs Administration Volpe National Transportation Systems Center (Volpe Center), is conducting an analysis of off-roadway crashes in support of the Intelligent Vehicle Initiative (IVI). The IVI accelerates the development and deployment of vehicle-based and vehicle-infrastructure cooperative crash countermeasures using intelligent technologies over seven problem areas: rear-end, off-roadway, lane change, crossing paths, driver impairment, reduced visibility, and vehicle instability...

The Northeast Florida Rural Transit Intelligent Transportation System project is a demonstration of ITS deployment in four rural Community Transportation Coordinator agencies.

This report presents the results of a qualitative study of driver perception of quality of service (QOS) on urban arterial streets. The purpose of the study was to identify the factors that are important to drivers of personal automobiles (non-commercial) regarding the quality of their driving experience. The study used an in-vehicle, on-the-road methodology in which drivers drove their own vehicles and talked out loud about the driving experience. This method provided the opportunity for drivers to respond to events as they occurred during the drive and to express their reactions to actual...

This report documents a modeling study performed as a follow-up to a qualitative online evaluation of the Traveler Advisory News Network (TANN) and SmarTraveler traffic information web sites (7,8) by researchers at the Volpe National Transportation Systems Center (9). The Volpe study found that users of these web sites perceived that they saved time and arrived on time more reliably as a result of accessing these web sites for real-time traffic information. As a follow-up to this qualitative study, the study presented in this paper uses an analytic approach using field data to empirically...

In the early days of automobiles when, for the first time in history, large numbers of people had opportunities to travel well beyond their local areas, finding directions was a problem. Prior to that, the range of most peoples' travels was limited to a relatively short distance from their home, and people quickly became familiar with the small network that they regularly used. Signage was not needed. However, as new drivers roamed into unfamiliar areas, the lack of signage made getting lost a common occurrence.
