The Growth Management Act (GMA) calls on local communities to rethink the traditional approach to transportation planning.  Transportation plans need to be consistent with the community’s comprehensive plan, under the GMA.  In addition, regions are to agree on a framework for transportation facilities and strategies.

• Multimodal Level of Service Analysis for Urban Streets  --  Multimodal Level of Service Analysis for Urban Streets explores a method for assessing how well an urban street serves the needs of all of its users.  The method for evaluating the multimodal level of service (MMLOS) estimates the auto, bus, bicycle, and pedestrian level of service on an urban street using a combination of readily available data and data normally gathered by an agency to assess auto and transit level of service.  The MMLOS user's guide was published as NCHRP Web-Only Document 128.
• Multimodal Leval of Service Analysis for Urban Streets: Users Guide  --  TRB's National Cooperative Highway Research Program (NCHRP) Web-Only Document 128, Multimodal Level of Service Analysis for Urban Streets:  Users Guide explores a set of procedures for predicting traveler perceptions of quality of service and performance measures for urban streets.  Quality of service and performance are considered in terms of the needs of auto drivers, bus passengers, bicyclists, and pedestrians.

  The final report on development of the multimodal level of service analysis for unban streets was published by TRB as NCHRP Report 616.
