CO₂ Emission Estimation Model for Regional Scale

Abstract

    There is a need to combine a traffic simulation model and a CO₂ emissions model for evaluating the reduction of CO₂ emissions caused by introducing ITS applications. In traffic simulations covering a wide area, estimates of traffic data should be based on two operating modes, stopped and steady-state running, because this reduces computational complexity and simplifies verification. A method for estimating CO₂ emissions that reproduces the acceleration energy from two-mode traffic data was developed. The method was verified with experiment data on various roads, and it was confirmed to have high CO₂ estimation accuracy.
