|The authors wish to acknowledge the assistance we received from
Sheriff Bob Braudis of Pitkin County and Chief Tom Stephenson of Aspen.
They welcomed this evaluation study, provided detailed records of the
operation of the program and assisted in nearly every aspect of the
study. David Hyman of High Mountain Taxi in Aspen was also very helpful.
David Ellison of the Colorado Department of Transportation was very gracious in providing the crash data for analysis and guiding us through the intricacies of the file.
To these individuals and the many others who helped with this project, the authors offer their sincere gratitude
