Impact of Public Transit Market Share and Other Passenger Travel Variable on CO(sub 2) Emissions: Amassing a Dataset and Estimating a Preliminary Statisticl Mode

摘要

Policies that encourage the use of more efficient transportqtion modes are considered beneficial in term of reducing carbon dioxide(CO(sub 2)) emissions. In support of developing such policies, the impacts of various transportation demand, suppply, and regulation variables on passenger travel related CO(sub 2) the predominant greenhouse gas(GHG) emission are investigated. A methodology for integrating data from multiple sources in a consistent manner is conceived and implemented, producing a dataset consisting of 146 of the largest urbanized areas in the US. A preliminary model for CO(sub 2) emissions per capita terms of various explanatory variables in this dataset is developed, the future improvements are suggested.
