Page viii Executive Summary Phases 1 and 2 of NCHRP 3-70 resulted in the multimodal level of service method (MMLOS) described in NCHRP Report 616, Multimodal Level of Service for Urban Streets. A Usersâ Guide was also prepared, NCHRP Web-Only Document 128. Both documents were published in the second half of 2008. The Final Report is available in both printed and electronic forms. 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 Phase 3 of this research During Phase 3 the MMLOS method was field tested in 10 metropolitan areas of the United States. The field tests had the following objectives: 1) To obtain public agency perspectives on the accuracy of the MMLOS level of service ratings for their community, 2) To identify any data collection difficulties that might discourage public agencies from applying the MMLSO method, 3) To identify any gaps in the guidance provided with MMLOS, and 4) To determine if any refinements to the MMLOS models would be appropriate. Public agency staff was extensively involved in the field tests. Agency staff was trained on the MMLOS method and software. They often performed the data collection, with assistance from the research team. This extensive involvement was primarily for the reason of helping public agency staff completely understand the MMLOS method so they could give accurate feedback on the method. But it also had the serendipitous result of establishing a core group of knowledgeable MMLOS users to help spread the news about MMLOS among public agencies in the United States. These field tests have resulted in several requests from additional agencies and local sections of the Institute of Transportation Engineers for presentations and workshops on the MMLOS method. Based on the results of these field tests several revisions were made to the spreadsheet software for implementing MMLOS. The spreadsheet reached version 10.5b by the conclusion of the field tests. The mid-block pedestrian crossing delay calculation was refined to take into account large medians. Several additional input error checks were added to the software. Input formats were revised to better facilitate data entry by public agency personnel. Additional guidance was provided during the course of the workshops and field tests to deal with conditions encountered in the field that were not anticipated when the original guide, NCHRP Web-Only Document 128, was written. This additional guidance is documented in the âResultsâ section of this final report. 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. These are also documented in the âResultsâ section of this final report.
