Highlights Density, entropy and intersection density effects on emissions are compared considering trip speed, vehicle characteristics and residential location. The sum of elasticities of three land use variables varies between −0.23% and −0.344%. Ignoring travel speed and vehicle characteristics in calculating transportation emissions can over-estimate built environments effects.
Abstract This study employs a multilevel model to compare the influence of land use on transportation emissions in urban and suburban areas when considering trip speed and vehicle characteristics. In the existing literature, transportation emissions are calculated with aggregate travel activity and emissions factors, however, emissions factors are sensitive to trip speed and vehicle characteristics, implying that considering those factors can change transportation emissions as well as the estimated effects of the built environment. Our results show that indeed this true.
