Driver drowsiness is a major, though elusive, cause of traffic crashes. As part of itsIVHS/human factors program, NHTSA is supporting research to develop in-vehicle systems .to continuously monitor driver alertness and performance. Scientific support for thefeasibility of this countermeasure concept is provided by research showing that: Drowsy driv

A travel survey conducted in Spring 1994 in Vermont is included in this report. The actual survey and accompanying cover letter sent to random households is the focus of this report. General information, such as why households were selected, the importance of their participation, and their privacy, for example, are addressed. The sample travel diar

This report documents the results of field testing of seventeen types of retroreflective raised pavement markers (RRPMs) installed in August 1992 at four interstate locations around San Antonio, Texas. Reflectivity measurements were taken periodically at each site using a portable reflectometer. These data were supplemented with laboratory reflecti

Economic growth along the Texas-Mexico border has prompted new concerns regarding the adequacy of that area's transportation infrastructure. In response, both the Texas Department of Transportation (TxDOT) and the Texas Turnpike Authority (TTA) are investigating ways in which the border infrastructure might be upgraded, either through new bridges a

The Georgia Department of Transportation (GDOT) has been constructing recycled asphalt pavements routinely for about four years. This research project was undertaken to evaluate the performance of recycled pavements in comparison to virgin (control) asphalt pavements.
The objective of this investigation was to evaluate the feasibility of using high-strength concrete in the design and construction of highway bridge structures. A literature search was conducted; a survey of five regional fabrication plants was performed; concrete mix designs were studied in the laboratory and in the field; tests of nine full-scale

Porous pavements or open graded asphalt mixtures have been in use in Oregon since the late 1960s. The use of this pavement type has increased over the years because the pores in the mat provide a better way for water to drain from the surface. This greatly increases the safety in the areas of skid resistance and splash and spray. Added benefits to
