Since the city of Charlottesville began operating its bus service in September 1976, there has been a 20% increase in patronage. City officials were interested in determining the reasons for the increase and any changes in the characteristics of the riders. Data from an on-board survey pointed to an increase from new riders rather than an increase

The study investigated the feasibility of using a coarse aggregate in the S-5 asphalt mixes. Virginia Department of Highways and Transportation specifications were adhered to with the exception of incorporating into the mix a small percentage of +1/2" material. A #78 aggregate was selected from three quarries in Virginia and substituted for the #8

Certain highway locations need exceptionally high skid resistance because of the alignment, geometry, and drainage of the roadway and the complex turning maneuvers required. Several beam specimens made of bituminous mixes incorporating unconventional aggregates with physical characteristics likely to produce high skid resistance were installed in a

The magnitude of potential highway user benefits and costs resulting from proposed highway improvements must be estimated with a reasonable degree of accuracy for highway agencies to make rational decisions in the public interest. There are procedures, some of which are computerized, in use or available for use to estimate user benefits and costs.
