The paper begins by reviewing the theories and previous research on TOD to establish a multiple regression model that analyzes the relationship as well as a model to calculate the accessibility index of a station area. Then, the paper illustrates an application of the model and method for the SMS. After the station areas are classified and clustered on the basis of the accessibility index, the model is applied to the clusters of the station areas. Finally, the estimated model of all station areas and of each cluster are compared and explained.
