Intelligent Transportation Systems at the 2002 Salt Lake City Winter Olympic Games Event Study - - - - - Traffic Management and Traveler Information Prepared by Lawrence Jesse Glazer and Roberto Cruz Iteris, Inc. for Utah Department of Transportation April 29, 2003 ACKNOWLEDGEMENTS This report was prepared under sponsorship of the Utah Department of Transportation, ITS Division, and the FHWA to document and assess the use of the UDOT traffic- management and traveler-information systems during the 2002 Winter Olympic Games in Salt Lake City. UDOT and the FHWA commissioned this study to create a lasting record of ITS experiences and lessons learned during the 2002 Winter Olympic Games. The principal authors of this report are Lawrence Jesse Glazer and Roberto Cruz, of Iteris, Inc., in Anaheim, California. Assisting in the study were S. Edwin Rowe and Mark Nuaimi of Iteris, plus Drs. Peter Martin and Joseph Perrin, of the University of Utah Traffic Lab. All information, findings, and opinions expressed herein are the opinions of the principal authors and do not necessarily represent opinions or policies of the Utah Department of Transportation. The authors gratefully acknowledge and thank the many transportation professionals in Salt Lake City who found time in their very demanding schedules before, during, and after the Olympic Games to provide assistance to the Study Team. Most notable among them was Samuel Sherman, who provided guidance and access to information. Thank you for assistance to Martin Knopp, Dave Kinnecom, Stan Burns, Peter Bigelow, Bryan Chamberlain, Steve Conger, Amanda Covington, Nile Easton, Andrew Gemperline, Gary Kuhl, Paul Jencks, Richard Manser, Jim McMinimee, Andre Sanchez, Denny Simmons (all from UDOT), and to all of the staff at the UDOT Traffic Operations Center. Thanks also to Richard Hodges (UTA), Pete Marshall (Gardner Siemens), John Grant (Transcore), Sgt, Dan Catlin (UHP), Amee Rock (PPCH), Russ Robertson (FHWA), Mike Morrow (FHWA) and Renee Sigel (FHWA) for providing valuable information. All the above people also deserve even greater gratitude for their remarkable dedication and hard work before and during the Olympic Games. Finally, thank you to Chintan Jhaveri, a graduate student at the University of Utah Traffic Lab who managed the data collection efforts of a dozen other graduates students during the study, and to every one of those students for their conscientious efforts. i Table of Contents 1 Executive Summary
