This research note reports an analysis of dwell times at bus stops using archived Automatic Vehicle Location/ Automatic Passenger Counter (AVL/APC) data reported at the level of the individual bus stop. The data provide a large number of observations that serve to better understand the determinants of dwells, including analysis of rare events, such as lift operations. The analysis of bus dwell times at bus stops is applicable to TriMet, the transit provider for the Portland metropolitan area, and transit agencies in general. The determinants of dwell time include passenger activity, lift operations and other effects: low floor bus, time of day and route type.
