The Fairfax Alcohol Safety Action Project (ASAP) was begun in January 1972 as one of thirty-five federally funded demonstration projects designed to implement and evaluate a comprehensive community alcohol countermeasures program. The Fairfax ASAP was approved for three years and funded with $2.1 million in an attempt to confront and ameliorate the

The objectives of this study were to verify the computer program used by the Virginia Department of Highways to predict highway sound pressure levels, to determine whether the accuracy and usefulness of the program could be improved, and to make recommendations for future research. In the report, the recommendations of NCHRP Report 117 are describe

The need for rural public transportation is coming into focus, although-Its magnitude is unknown because of limited data. This study was initiated to develop an efficient and economical methodology for determining the transportation needs of the rural population. A case study was conducted in one rural county so that any potential problems could be

The purpose of the research was two-fold: (1) to provide persons in the Department who prepared impact statements a guide to the effects that highway improvements had on the economic activity of an area, and (2) to place in proper perspective the use of user and nonuser impacts as measures of the costs and benefits of highways.
The Virginia skid vehicle has been equipped with a digital data recording system to provide rapid reduction of skid measurement data. It was found that five to ten minutes are required to evaluate a single measurement using the original analog strip chart system, whereas the digital results for a full day of testing can be evaluated within a matter
...
A manual was prepared for use in estimating soil losses and designing adequate abatement structures along the ditch lines of roadways. These tasks were to be accomplished by a computer program intended to be used on the IBM Model 370 computer. The manual was intended for use by personnel of the Location and Design Division and Environmental Quality

The Commonwealth of Virginia randomly distributed 100,000 sets of experimental reflectorized and 100,000 sets of control nonreflective 1971 license plates, Each Division of Motor Vehicles distribution point in the state received and sold a pro rata number of each type. Plates were distributed evenly throughout each day of the distribution period. A

The 10-year study of asphalt pavement behavior described herein was initiated to follow the changes that occur with time and traffic and to supplement existing information on material properties that contribute to more durable pavements. Measurement of surface characteristics and sampling of asphalt concrete and stone base were conducted twice year

Of the twenty-four Action Plans perused, several were very general in their approach to citizen participation while others were very specific. The twelve chosen for presentation here were the ones taking the most specific approaches. Although these twelve vary greatly with respect to their specificity, the states generally take two approaches to th

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
...
The main objective of this study was to establish the factors that influence the durability of the surface configurations that are used or can be used to provide high and long lasting skid resistance for portland cement concrete pavements. In the development of such durable surface texture an insight into the pavement wear mechanism in the presence
...
The current practice in Virginia is to reflectorize and illuminate all overhead highway signs because of their important role in the safe and orderly flow of traffic. Reflectorization is obtained by using reflective sheeting as background and legend materials, and diffuse illumination is provided on the sign surface by lighting fixtures. The perfor

This report marks the conclusion of the third phase of the Metropolitan Plan Evaluation Project. Findings of both phases two and three are summarized here. More detailed and technical results have been reported previously. The continuing metropolitan planning process consists of a complex of activities involving elected and appointed decision maker

In response to an urgent request from the Materials Division, a literature search was conducted to find a suitable analytical method for the determination of chloride in hardened concrete. It was found that an ion-specific potentiometric method employing a chloride-extraction procedure improved by H. A. Berman of the Federal Highway Administration
...
In response to its own research and observations in the early 1960's the Virginia Department of Highways mounted an intensive and extensive effort to improve the performance of concrete in bridge decks. Major elements of this effort included (1) a training and certification program for Department and industry personnel and (2) improved and upgraded
