Abstract

Urban transportation is a significant contributor of greenhouse gas emissions. Despite this, transportation planning projects are generally not optimized directly for greenhouse gas emission reduction because there are few practical tools available that quantify the impact of specific project features. Ideally, physics‐based micro‐simulations would be used to evaluate project features within large‐scale networks to properly capture local driving behavior and extended traffic shifting effects. This is generally not practical because micro‐simulations require excessive computational resources. A transportation emissions model, which includes a simplified micro‐simulation, is described. This model micro‐simulates transportation emissions across large‐scale networks such that emissions from a metropolitan region can be calculated for multiple design options in a few hours on a personal computer. A variety of case studies are presented which demonstrate the utility of practical large‐scale micro‐simulations for transportation emissions. The requirement for large‐area models is shown by scenarios which demonstrate traffic shifting effects due to local changes in network capacity.
