A Basic Research on Formulation of CO₂ Emission Mechanism of Urban Passenger Transport and its Application to an Actual City

Abstract

This research aims at establishing a macro-type estimation method of CO₂emission from passenger transport at city level, which can consider the difference in car ownership level and transport infrastructure level as a tool for investigating CO₂reduction countermeasure in transport sector. At first, the basic formula that describes the mechanism of CO₂emission amount is shown, and it is modeling in detail. Changes in fuel economy and CO₂emission according to driving situations on roads are included. Estimation and sensitivity analysis are carried out by applying this method to Nagoya city. It enables us to estimate the changes in CO₂emission by transport properties, namely frequency distribution of trip length, car ownership and transport infrastructure level.
