    This research evaluates the hypothesis suggesting that organizational characteristics of transportation institutions have an impact on their transit system’s ridership. It is important to emphasize that this research is not oriented towards the estimation of ridership, but to identify if organizational characteristics may be used or discarded as part of a set of estimators. The methodology used includes: * A literature review used to gather background information related to organization and transportation theoretical frameworks. * Inspection of study cases to identify organizational characteristics that may have had some influence in their ridership performance. * Development of a questionnaire for an on-line survey, using the study cases and literature review as background. The survey was used to identify variables available to test the suggested hypothesis. * A correlation analysis using Eta correlation ratio was performed in order to identify relations between ridership and organizational characteristics of the sample. Variables having the highest correlation and with appropriate results on the corresponding hypothesis test were analyzed through a multiple classification analysis (MCA). The MCA was performed for individual variables and combinations of two and three variables. The MCA models were applied to the originally excluded cases of San Juan, Puerto Rico. A percentile bootstrap model prediction averaging was used in order to obtain a mean annual ridership per service population estimate. Results from models containing organization’s internal environment variables resulted in estimates that, for the case study of PR, were much more similar to the real value than the estimates from models related to capacity or transportation variables only. Therefore, there is not enough evidence to discard that the transit organization has a direct impact to transit ridership. It was concluded from the results of the Eta Correlation Ratio and Multiple Classification Analysis that there is a correlation between some organizational characteristics of transit institutions and their transit ridership. Therefore, a framework describing current transportation relationships should highlight the organizational component.
