A Trial to Estimate the Impact of Improvement of Road Transportation Facilities Applying a Fuel Consumption Model

Abstract

Data are collected on the actual traffic flow and road environment using a vehicle equipped with measuring instruments, and instantaneously traffic stream data are also collected by traffic detectors.The relationship between traffic stream condition and vehicle fuel consumption is analyzed. The defference of fuel consumption structure between in congested flow and in uncongested flow is found. A fuel consumption model is applyed to estimate the impact of improvement of Tokyo Metropolitan Expressway network. An estimation of the impact on energy consumption in selected road section is tried.
