Niemeier, Debbie A., Thirayoot Limanond, Jennifer Morey (1999) Data Collection for Driving Cycle Development: Evaluation of Data Collection Protocols. Institute of Transportation Studies, University of California, Davis, Research Report UCD-ITS-RR-99-22
The purpose of the study was to evaluate the potential biases associated with the use of current chase car protocols as well as identifying and recommending solutions to problems in the actual data used to determine driving cycles. To evaluate potential biases in the chase car protocol, data collected in Los Angeles, CA in 1992 as well as chase car data from Baltimore, MD and Spokane, WA were examined. The chase car protocol itself was also investigated. Consideration was given to the relative advantages and disadvantages of instrumented vehicle and chase car data.
The current study has several objectives: 1) to review and evaluate the current chase car protocol; 2) to review and compare instrumented vehicle data to chase car data; 3) to evaluate GPS technology for use in future data collection procedures; and, 4) to recommend refinements to the existing chase car protocol. The object is to suggest adjustments to the current chase car protocol and to explore several possible new data collection methods.
