Based on the 2015 transportation CO2 emissions and economic and social data for the 286 cities in China, exploratory spatial data analysis (ESDA) method and a geographically weighted regression (GWR) model were used to analyze the spatial distribution characteristics of transportation CO2 emissions and their influencing factors. The results showed that the CO2 emissions from urban transportation in China featured significant spatial agglomeration. The high emission areas were mainly concentrated in Beijing, Shanghai, Chongqing, Chengdu, Nanjing, and other regional core cities, while the low emission areas were mainly concentrated in the cities of Gansu, Guizhou, Yunnan, and other underdeveloped provinces. Considering the overall evolution of the factors affecting transportation CO2 emissions, private car ownership, technological innovation, and industrial structure correlated positively with transportation CO2 emissions. Population density, urbanization rate, per capita urban road area, and transportation structure could significantly inhibit transportation CO2 emissions. The impact of per capita GDP, public transportation, and environmental regulation on transportation CO2 emissions was insignificant. From the perspective of spatial heterogeneity, there were significant regional differences in the impact of various factors on CO2 emissions. Private car ownership, technological innovation capacity, and per capita GDP all had a positive impact on transportation CO2 emissions. Urbanization rate, urban road area per capita, and transportation structure all had a negative impact on transportation CO2 emissions. Population density, industrial structure, public transportation, and environmental regulation all had a two-way impact on transportation CO2 emissions in different cities.
