Bus On-Time Performance
Definition: Measures how closely the service ran to the schedule, as experienced by the customer. Departure is considered on-time, if made between 0 and 5 minutes after scheduled departure time. 30 seconds are added to both ends of the 0 to 5 minute interval to capture deviations between the various time-tracking devices. Many factors affect bus on-time performance. Some are within MARTA’s control (e.g., mechanical or driver problems). Others, such as traffic or unplanned detours, are not. Regardless of cause, MARTA strives to work around problems.
