The accuracy and cost-effectiveness of short-period manual traffic counts are analyzed. Alberta's primary highway system is investigated in this study. The roads in the system under investigation are classified into four types: (a) commuter sites, (b) nonrecreational low-volume sites, (c) rural long-distance sites, and (d) recreational sites. The accuracy of short-period counts is expressed in terms of a deviation either side of the estimated volume, which defines limits of the interval in which the actual volume is most likely to be. In the tests of this study, a relative measure of deviation, namely, the coefficient of variation, is used in order to compare the variation in several sets of data for the counts of different durations and schedules. The analysis carried out in this paper illustrates clearly that the most important considerations for rationalization of short-period manual counts are (a) the type of road site being surveyed and (b) the hour-to-hour traffic variations within the same day. The month of the year, the day of the week, and the duration of counts are other significant factors that must be considered in order to devise the most efficient short-period counts. (Author)
