Abstract

There have been several studies on the estimation of trip distributions using observed link-flow. The accuracy of the estimation depends largely on the location and the number of the traffic counts in the network. In this paper, two methods are proposed which will enable us to extract the effective links for the estimation of trip distributions. One is a method for the direct estimation of trip distributions, named the "OD-covering method" and the other is for the estimation of trip generations, named the "zone-covering method ". These two methods were applied to the trunk road network in the Fukuoka City Region, and the results of the estimation were sufficiently accurate based on the link-flows that were observed on the extracted links in the solution.
