    As part of the Fairfax Alcohol Safety Action Project (ASAP), staff members of the Virginia Highway Research Council, acting in their role as evaluators of the project, conducted a baseline survey of the nighttime drinking-driving patterns in Fairfax, Virginia. The ASAP concept recognizes the major role alcohol plays in fatal and serious highway cra ...
  • Design concepts concerning the multiple use of transportation rightsofway
    Design concepts concerning the multiple use of transportation rights-of-way.
    Zuk, William
    1974-01-01 | PDF
    The growing shortage of available land is generating a great deal of interest in the utilization of transportation rights-of-way for uses other than for vehicles. Such structures as air-rights buildings and enclosed pedestrian bridges between buildings are examples of some of the ways rights-of-way are currently being used for purposes other than v ...
  • An evaluation of the systems approach to bridge design
    An evaluation of the systems approach to bridge design.
    McKeel, Wallace T ;
    Korf, Jerry L
    1974-01-01 | PDF
    This study contains the findings from a survey of available integrated computer systems for bridge analysis and design, along with a sample design of a grade separation structure using the two leading design systems, BEST and STRC. It appears that integrated design systems could be applicable to the design of common highway bridges in Virginia, and ...
  • Investigation of asphalt content design for opengraded bituminous mixes
    Investigation of asphalt content design for open-graded bituminous mixes.
    Maupin, G. W
    1974-01-01 | PDF
    Several design procedures associated with determining the proper asphalt content for open-graded bituminous mixes were investigated. Also considered was the proper amount of tack coat that should be placed on the old surface prior to paving operations. The design procedures obtained from other highway agencies were evaluated in the laboratory for t ...
  • A study of the review and comment phase of the draft environmental impact statement

  • Evaluation of rumble strips
    Evaluation of rumble strips.
    Franke, Kurt A
    1974 | PDF
    Rumble strips have been used for a number of years at locations where a physical stimulus was needed to alert a motorist to some hazard. However, little study has been done to determine the optimum spacings for the strips. Through testing existing Virginia rumble strip installations and various spacings at a test location, a basis was established f ...
