Year: 2001 Prior TransNow funded research by Portland State University (PSU) and the University of Washington (UW) in cooperation with Tri-Met, the transit provider for the Portland metropolitan area, has utilized a rich set of archived data from the Automatic Vehicle Location (AVL)-based Bus Dispatch System (BDS). Tri-Met is one of the few transit agencies that archive AVL data for analysis and research.

  Citation × Citation Citation Abstract Copy Title: Automated Bus Dispatching, Operations, Control, and Service Reliability: Baseline Analysis Author: Strathman, James G., Dueker, Kenneth, Kimpel, Thomas J., Gerhart, Rick, Turner, Ken, Taylor, Pete, Callas, Steve, Griffin, David, Hopper, Janet Year: 1998 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 and actively employed by dispatchers and field supervisors, and when performance data is used in wriling schedules. The baseline analysis documents service reliability on eight routes that were selected to be representative of the typology of routes in Tri-Met's system. Data on weekday run times, headways, and on-time performance were recovered over a two week period in November 1996. Findings from analysis of these data are presented in this report.
