While the link between urban structure and commuting has been well discussed, scant studies analyzed the impact of urban structure on commuting as well as traffic congestion at the individual level. This paper described urban structure by identifying different types of employment centers (i.e. high-job density center, medium-job density center, and non-job centers) and analyzing the jobs-housing balance around residential areas. Then, we investigated how urban structures affect commuting and traffic congestion at individual level while considering socio-economic factors. The results showed people who worked at high job density centers while live at non-job centers had longest commuting duration. People who work at high density job centers experience longer traffic congestion compared with those who work at medium and non-job centers. A balanced jobs-housing was associated with less commuting distance and duration but had no significant effect on traffic congestion. As the workplaces were further from the urban center, commuters tend to travel less. The result indicated the decentralization of jobs and formation of subcenters contribute to shortening commuting and alleviating traffic congestion.
