Prediction Performance of Carbon Dioxide (CO2) Emissions Models Incorporating Land Use, Trip, Socioeconomic, and Demographic Characteristics

This study investigated the relationship between CO2 emissions with land use, trip characteristics, socioeconomic, and demographic characteristics for two time-periods (2001 and 2009). A carbon dioxide (CO2) emissions model was formulated and estimated using disaggregate travel data incorporating land use, socioeconomic, and demographic characteristics for both total and five common trip purposes. Further, the study investigated the predictive performance of all models in their estimation data and a different dataset for 2001 models. The study results show that the increase in urbanization reduces CO2 emissions and the increase in population density decreases CO2 emissions. Specifically, on average, urban trips produced relatively less amount of CO2 compared to rural trips. Of all the vehicle types, sport utility and recreational vehicles were found to have higher impact on CO2 emissions than other vehicles. In addition, automobile/car/station wagon were found to have the lowest effect on CO2 emissions compared to other vehicle types. Despite the increase in vehicle fuel efficiency and use of alternative fuels, the 2001 models were able to explain CO2 emissions in the 2009 dataset satisfactorily.
