Transit Service Reliability: Analyzing Automatic Vehicle Location (AVL) Data for On-Time Performance and Identifying Conditions Leading to Service Degradation Final

Transit agencies are increasingly using AVL data to support key performance indicators, for responding to service
complaints, or for reviewing and improving the quality of service. The main objective of this study was to
investigate the use of AVL data for improving transit service reliability: 1) improving on-time performance, and
2) monitoring bus schedule adherence and bus bunching. Static and real-time General Transit Feed Specification
(GTFS) data from HART and data from the MDT AVL system were used.  Contact Joel Volinski for more information.
