A STUDY ON THE CHANGE OF FREIGHT TRANSPORT BY ROADPRICING

Abstract

The main purpose of road pricing policy is to improve air environment, but there is little existing research which analyzed the change of freight transport, which has big influence to air environment, at the time of implementing road pricing. Then, in this paper, we classify the specific changes of freight transport by road pricing, and especially analyze change of transshipping freight and change of freight car OD resulting from it. We build methodology for describing whether goods is delivered directly to destionation or is transshipped at distribution center on the way with discrete choice framework. We also propose a process of building data required for the model estimation from a goods flow survey. Finally, the model is applied to cordon pricing currently planned in Tokyo central area.
