In recent years, the number of automobiles registered in Japan is still increasing and thereby typical phenomena of a traffic jam of automobiles are now seen everywhere in city streets. In order to suppress a traffic jam, various schemes of traffic control are put in force: This paper proposes a technique of computation for the estimation of a spot traffic volume which may play an essential role in traffic control. At first a relation between the sample size and the distributions of sample mean and sample variance for the statistics of a spot traffic volume is discussed. In the second, a yearly statistical characteristics of the spot traffic volume is analyzed and, subsequently, monthly, weekly, and daily characteristics are investigated. Based on this analysis, a computation technique for the estimation of a spot traffic volume is proposed. Finally, by the use of hourly traffic volume data which were recorded at an observatory beside the Route 2 national main road in Fukuyama city, the computed estimation error for the proposed technique is examined.
