We have developed a model that enables us to estimate the traffic volume at non-observed road sections. This model needs the observed traffic volumes at other sections and the constitutional ratio of OD volume on each section in the road network. In this paper, the approximate equation of the error that is produced in the process of the estimation is introduced, and then the reliability of the estimation method is analyzed. Finally the effective and essential links for estimation of traffic volume were extracted from the road network including Fukuoka City Region using the branch and bound method.
