Site Location Study For An Integrated Traffic Data Collection System: Phase 1 Report, Kenneth Dueker, Richard Ledbetter, Bruce Rex

Center for Urban Studies Publications and Reports

Improved technology for counting, classifying, and weighing vehicles in the highway traffic stream is becoming increasingly available. Research has been undertaken to make effective use of these new technologies, not just to replace current data collection programs of counting, classifying, and weighing with more efficient versions. This reports on the Phase I research, which had three major objectives;

• a literature review to guide the analysis of alternative methods;
• a statement of requirements to modernize and integrate the data collection programs of traffic counting, vehicle classification and truck weights, and to identify the type and use of traffic data for design, …

An Evaluation Of Automatic Passenger Counters: Validation, Sampling, And Statistical Inference, James G. Strathman

Center for Urban Studies Publications and Reports

While automatic passenger counters (APC's) offer the potential for cait effective data recovery and management, they also introduce new complications in the data recovery process. This report addresses three issues associated with the implementation of APC's, 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 APC's compatible with UMTA's Section 15 reporting requirements. Third is the issue of inferring system-level ridership from …
