This study was conducted by a team of researchers at the Institute of Transportation Studies, University of California at Berkeley, with funding from the California Office of Traffic Safety. Ted Chira-Chavala directed the study, coordinated the write-up of the final report, and wrote many chapters. Douglas Cooper was the key researcher, who performed the literature review, worked with key personnel of Upland Police Department to acquire essential data for the evaluation, analyzed the data, and contributed significantly to all chapters. David Gillen performed all time-series analyses and contributed very significantly to chapters four and five. This study would not have been possible without the tireless assistance from Captain John Cannon of Upland's Police Department. He provided traffic citation, crash, personnel, and financial data essential for the evaluation. His cooperation is gratefully acknowledged. Finally, the findings and opinions expressed in this report are solely those of the authors, and do not necessarily reflect or represent opinions of the sponsor or Upland Police Department.
