Transportation Modeling For The Environment: Final Report

This report describes preliminary research dealing with vehicle emissions associated directly with Automated Highway Systems (AHS) and ramp metering. In performing this analysis, a power-demand model emissions model was integrated with several transportation simulation models in order to quantitatively determine the effects of Intelligent Transportation Systems (ITS) technology on vehicle emissions. For AHS, a steady-state speed/emissions comparison was conducted between vehicles that are platooned and non-platooned. For ramp metering, a general evaluation was conducted concentrating on the effect of vehicle emissions.
