This paper presents a simulation study to evaluate the capacity and the optimum service cycle time of a demand responsive transit feeder service within the colonia of El Cenizo, TX. Demand data are taken from a survey questionnaire conducted to evaluate the existing travel patterns and the potential demand for a feeder service. Results showed that a single shuttle would be able to comfortably serve 150 passengers per day and that a fleet of 7-8 vehicles would be needed to serve the residential area. The optimal cycle length between consecutive departures from the terminal should be between 11-13 minutes for best service quality. This exploratory study can serve as a first step towards improving transportation services within these growing underprivileged communities, but also other residential areas, especially those with demographics and geometry similar to our target area of El Cenizo.
