Volume Studies

Engineers often use counts of the number of vehicles or pedestrians passing a point, entering an intersection, or using a particular facility such as a travel lane, crosswalk, or sidewalk. Counts are usually samples of actual volumes, although continuous counting is sometimes performed for certain situations or circumstances. Sampling periods may range from a few minutes to a month or more. The length of the sampling period is a function of the type of count being taken and the use to which the volume data will be put. This chapter will focus on the common methods for counting traffic in the field; how volume data are sampled, expanded, and analyzed; and how count programs are established. Brief descriptions of specific studies are presented along with references containing more detail. Examples throughout the chapter show field data collection and summary forms. Various methods used to perform traffic volume counts are described.
