Impact of Household Characteristics on Household Daily Traffic Emissions Using Household Travel Survey Data

This study aimed to investigate the effects of household characteristics on household vehicle emissions. The household travel survey data conducted in the Jiangning District of Nanjing City, China were used. The vehicle emissions of household members’ trips were calculated by using the average speed emission factors. Descriptive statistics analysis showed that the average daily emissions of CO, NOₓ and PM₂.₅ per household are 8.66g, 0.55g and 0.04g respectively. The household emissions were found to have imbalanced distributions over households. The top 20% household were responsible for nearly two thirds of the total emissions. Based on the one-way ANOVA tests, the means of CO, NOₓ and PM₂.₅ emissions were found to be significantly different over households with different member number, automobile number, annual income and access to subway. Finally, the household daily vehicle emissions were linked with household characteristics based on multiple linear regressions. The regression analysis results showed that the household members, vehicle ownership, household annual income, housing type and access to subway are the main factors contributing to household daily vehicle emissions.
