The provision of adequate facilities for traffic has always been a problem but the development of the motor vehicle has demanded a new approach to the problem. From traffic volume data collected in the past analyses have been made to arrive at a reliable method of estimating present day and future traffic volumes. To study traffic volumes on each road in detail would be impossible and a traffic counting system has had to be developed in which typical samples of traffic volumes, control counts, are taken and estimates made from infrequent short term traffic counts, coverage counts, in the road system. The theory of probability of error in a normal distribution is used to determine the probable error in the control and coverage counts.
