Transit-Oriented Development (TOD) has become the dominant policy used to achieve the sustainable urban development in the United States. Accessibility, as a measure that relates the transportation network to the pattern of activities that comprise land use, provides a useful framework for the integration of transport and land use planning. This paper provides a systematic analytic approach to investigate the TOD and accessibility in the whole urban area. We applied the node-place model to evaluate and classify station areas, calculated the TOD score and transit accessibility score based on the cumulative accessibility measure,and enhanced the node-place model to identify unbalanced areas. Results shows that the transportation supply cannot match the urban activities for the majority of station areas in Portland and Los Angeles. The patterns of TOD score differ across the different study areas and different patterns of transit accessibility score have a different degree of spatial concentration. Most unbalanced areas can be classified as the first type of unbalanced areas, where have above average TOD score and below average transit accessibility score. The improvement of the node-place model enables the researcher to identify strategies that help planners to balance TOD and transit accessibility for better returns of relevant investments.
