Traffic volume data, especially Average Annual Daily Traffic (AADT) volumes, are very important in transportation engineering for managing and maintaining existing facilities, and for planning and designing new facilities. This paper addresses the traffic count analysis system developed to produce AADTs for freeway links based on traffic count data. For freeways, traffic counts are usually taken at certain links, and then they are processed to obtain AADTs. This processing is very time-consuming and labor-intensive when performed manually. The objective of developing the TCAS is to reduce the time and labor required in the processing of traffic counts to obtain AADTs. The TCAS was developed based on data coaptation and data reconciliation techniques which are frequently used in the processing of network flow rate data. The TCAS can be used to calculate AADTs for counted links, to generate AADTs for uncounted links, and to adjust these AADTs to satisfy material balance. It is expected to significantly reduce the time and labor required for processing traffic volume data for freeways.
