Using Archived AVL/APC Bus Data to Identify Spatial-Temporal Causes of Bus Bunching
Background
This study analyzes potential causes of bus bunching that can be analyzed with available archived bus dispatch system (BDS) data, which includes automatic vehicle location and automatic passenger count information, from TriMet’s Route 15 in Portland, Oregon.
Lessons Learned
It is suggested that transit operators consider moving from a schedule-based service to a headway-based service during high frequency service hours to reduce bus bunching. Late departures of the first bus and on-time or early departures of the following bus are major causes of bus bunching.
