... 5 S E C T I O N 1 1.1 Research Problem APTA's Recommended Practice for Quantifying Greenhouse Gas Emissions from Transit (2009) describes three categories of emissions displaced by transit and provides methodologies for their quantification: • Avoided car trips through mode shift from private automobiles to transit (referred to as the ridership effect in this research or the direct effect of transit in some other studies)
From page 6...
... 6 Quantifying Transit's Impact on GHG Emissions and Energy Use -- The Land Use Component • Identify, describe, and, to the extent possible, quantify the synergistic interaction between transit and land use and the effects on transportation-related GHG emissions and energy use. The project accomplished all stated objectives, with one exception: quantification of the "synergistic interaction between transit and land use," meaning the mutually reinforcing aspects of transit service and compact urban forms.
From page 7...
... Introduction 7 systems are captured in this research, including benefits in terms of VMT, energy, and GHG emissions reductions. • Section 3 -- Research Methodology summarizes the statistical methodology used.
