Research Note: Determinants Of Bus Dwell Time, Kenneth Dueker, Thomas J. Kimpel, James G. Strathman, Steve Callas

Center for Urban Studies Publications and Reports

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 …

Automated Bus Dispatching, Operations, Control, And Service Reliability: Baseline Analysis, James G. Strathman, Kenneth Dueker, Thomas J. Kimpel, Rick Gerhart, Ken Turner, Pete Taylor, Steve Callas, David Griffin, Janet Hopper

Center for Urban Studies Publications and Reports

The authors of this report are engaged in a long term project to assess the impacts of Tri-Met's BDS on service reliability and transit use. The framework designed for this assessment focuses on documenting service reliability and passenger activity at three major junctures:

• The pre-operational (baseline) period;

• The initial (passive) period following implementation of the new system, when both drivers and dispatchers have access to schedule adherence information in real time, but before the development and use of operations control practices that exploit the information generated by the system;

• Full implementation, when operations control practices are defined …
