Page 1 1. Introduction Public agencies need to be able to evaluate the transportation services of their roadways from a multimodal perspective. They need to be able to assess the tradeoffs when they reconstruct existing streets or design new streets to better serve all of the modal users of their facilities (auto, transit, bicycle, and pedestrian). This ability is needed to better meet the objectives of the Transportation Equity Act for the 21st Century (TEA-21) and its predecessor the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) for better incorporating the perspectives and needs of transit, pedestrian, and bicycle users into the planning, design, and operation of the U.S. transportation system. The objective of the first two phases of the 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 for the interaction among the modes. The first two phases of NCHRP 3-70 resulted in a published final report, NCHRP Report Number 616, âMultimodal Level of Service for Urban Streetsâ, and a âUserâs Guideâ, NCHRP web-only document Number 128. Research Objective The objective of Phase 3 of the NCHRP 3-70 project has been to field test the recommended methodology with various public agencies around the United States. This objective was accomplished through training of public agency technical staff on the NCHRP 3-70 multimodal level of service (MMLOS) method, testing the method on various prototypical urban streets, and obtaining feedback from public agencies on any needed refinements to make the MMLOS method a useful tool for evaluating the multimodal level of service provided by urban streets. The Research Plan The research plan consisted of the following tasks: 0. Development of Amplified Work Plan 1. Recruit Volunteer Agencies 2. Training of Agencies 3. Data Collection for Test Arterials 4. Analysis of Level of Service for Test Arterials 5. Assessment of Results of Tests 6. Refinement of Multimodal LOS Methods 7. Final Report
Page 2 This Report This report is organized into three chapters. Chapter 1: Introduction, describes the objectives of the Phase 3 research, its work plan, and the organization of this report. Chapter 2: Field Test Procedures, describes the various steps of the field testing process. Chapter 3: Results, presents the results of the field tests for each modal level of service model and identifies any recommended refinements to the models and any suggested additional guidance for applying the level of service methods.
