AN EVALUATION OF AUTOMATIC PASSENGER COUNTERS: VALIDATION, SAMPLING AND STATISTICAL INFERENCE. FINAL REPORT

This report addresses three issues associated with the implementation of automatic passenger counters (APCs), based on an evaluation of the recent experiences of the Tri-County Metropolitan Transportation District of Oregon (Tri-Met). First is the issue of validation, which is concerned with both the recovery and accuracy of APC passenger data. The second issue concerns the development of a sampling methodology for APCs compatible with UMTA's Section 15 reporting requirements. Third is the issue of inferring system-level ridership from sample data in the presence of selective APC failures.
