This study uses the accessibility-based evaluation method to unpack the interaction effect of transit oriented development and a new transit hub, using the San Francisco Transbay Transit Center Development Plan project. We reveal both the transit oriented development and transit changes positively affect accessibility to jobs and accessibility to workers. However, the magnitude of effects for the transit changes alone are minimal in comparison to the effects of the anticipated transit oriented development changes. This indicates that in areas where there already is transit service, the development of land near the transit service can have a greater impact on accessibility levels than the improvement of connections between transit services. We also unravel the increase in accessibility at the project-level and determine that the increase is greater than the sum of the contributions of the individual portions of the project. This demonstrates that transit changes and transit oriented development have a superadditive effect, although it is negligible in our case.
