Through the addition of automated scheduling and dispatch (ASD) technology to its Community Transit operations, the Suburban Mobility Authority for Regional Transportation (SMART) has sought to improve its paratransit operations along several dimensions. Among these potential improvements, SMART hopes to improve its schedule adherence, meaning that it seeks to do a better job of having Community Transit buses arrive when customers are told that they will arrive.
From the paratransit customers’ perspective, both early and late arrivals can be problematic, as the former may mean that a customer is not prepared to leave when the bus is, and the latter means that the customer may well arrive late for some other appointment The latter situation may be even worse for late arrival at the destination. Thus, adherence to the daily schedules represents an important measure of service quality. This report provides a quantitative basis for evaluation of the performance of SMARTs ASD (a product called TrapezeTM-QV, or simply Quo Vadis1) in the area of schedule adherence, including measures of pickup arrival time, destination drop-off time, and on-board travel time, especially deviations of these from daily trip schedules.
