Productivity measures based on vehicle-hours that start from the moment a vehicle leaves the garage until the moment it returns to the garage are selected to evaluate alternative operational strategies. Management operational policies from two different Dial-A-Ride systems are studied (Gaithersburg, Maryland, and Rochester, New York). Gaithersburg operates a small, manual system in a suburban community with limited public transit service. The Rochester system is considerably larger and partially automated; it operates in a community served by a multimodal conventional transit system. The Gaithersburg system has an above average vehicle productivity of 8.1 passengers per vehicle-hour, and the Rochester system has a vehicle productivity of 5.5. The vehicle-time data collected from these two Dial-A-Ride operations indicate that Gaithersburg has higher demand density, higher group pickup and group drop-off factors, lower interstop running times, and a lower percentage of nonproductive time than the Rochester system. Important operational strategies for improving vehicle productivity stated in this report are those that lead to reduced interstop running time, reduced pickup dwell time, increased group pickup and group drop-off factors, and reduced nonproductive time.
