This paper aims to propose an estimation method of traffic volume for non-arterial roads that serve as alternate routes of arterial roads. The estimation method uses the correlation “the dependence index on traffic volume of arterial road” between the traffic volumes of the arterial roads and it alternate non-arterial roads. Analysis of the similarity between non-arterial road and arterial road shows that the existence of high dependence road and low dependence road, and the dependence index on traffic volume of arterial road formula is calculated with the use of explanatory variables of the arterial road which include road wideness, link length, and speed limit etc. This result reveals a possibility to add "traffic volume of arterial road" that is observed as explanatory information to traditional variable of estimation method of traffic volume of non-arterial road.
