NOTES: Data from 1995-2000 and 2001-2003 are not comparable due to a methodology change. Interruptions of service include major and minor mechanical failures. Since 2001, if the vehicle operator was able to fix the problem and return the vehicle to service without assistance, the incident has not been considered an interruption of service. Other generally includes automated guideway, Alaska Railroad, cable car, ferryboat, inclined plane, jitney, trolleybus, aerial tramway, and vanpool. However, aerial tramway data are not included prior to 2003, Alaska Railroad data are not included prior to 2001, and jitney data are not included in 2000 or 2001.
