Page vi Acknowledgments The research reported herein is Phase 3 of NCHRP Project 3-70. It was performed by Dowling Associates, Inc., Oakland, California. Dr. Aimee Flannery of George Mason University conducted the Arlington County, Virginia workshop, assisted in data collection and analysis, and provided advice regarding the performance and assessment of the auto level of service model. Dr. Nagui Rouphail of the North Carolina State University conducted the assessment of the field test results for the auto level of service model. Mr. Paul Ryus, with the assistance of Mark Vandehey, Christopher Tiesler, and Nick Foster, all of Kittelson Associates conducted the Boise, Idaho and Portland, Oregon workshops, and assisted local agency personnel in the data collection and analysis. Mr. Bruce Landis, Mr. Theodore Petritsch, and Peyton McLeod of Sprinkle Consulting, Inc., conducted the Atlanta, Georgia, and San Antonio, Texas workshops. They also assisted local agency personnel in data collection and analysis. They provided advice on the assessment and refinement of the bicycle and pedestrian LOS models. The authors would like to thank the management and staff at the following agencies for participating in the field testing of the NCHRP 3-70 multimodal level of service models. Arlington County, Virginia Atlanta Regional Commission, Georgia City of Boise and ADA County Highway District, Boise, Idaho Delaware Valley Regional Planning Commission, Philadelphia, Pennsylvania City of Portland, City of Hillsboro, City of Gresham, Oregon San Antonio-Bexar County Metropolitan Planning Organization, San Antonio, Texas City of San Diego, California The authors are indebted to the Florida Department of Transportation for funding and hosting their own extensive series of workshops and field tests of the NCHRP 3-70 method by the metropolitan planning organizations of Tallahassee, Tampa, and Orlando, Florida.
Page vii Abstract The objective of the first two phases of NCHRP 3-70 project was to develop and test a framework and enhanced methods for determining levels of service for automobile, transit, bicycle, and pedestrian modes on urban streets, in particular with respect to the interaction among the modes. Phase 2 resulted in the multimodal level of service method (MMLOS) described in NCHRP Report 616, Multimodal Level of Service for Urban Streets. The objective of phase 3 of NCHRP 3-70 was to field test the MMLOS method with various public agencies around the United States. This Final Report presents the results of this third phase 3 of the research During Phase 3 the MMLOS method was field tested in 10 metropolitan areas of the United States. Public agency staffs were trained on the MMLOS method and itâs implementing software. They assisted in data collection and evaluated the suitability the MMLOS method for use within their agency. Based on the results of these field tests several revisions were made to the spreadsheet software for implementing MMLOS. Additional guidance was provided to deal with conditions encountered in the field that were not anticipated when the original guide, NCHRP Web-Only Document 128, was written. Finally, a few minor modifications to the pedestrian level of service model are recommended to improve its sensitivity to some of the conditions encountered in the field tests.
