Multimodal Level of Service Analysis for Urban Streets

December 09, 2009

As state and local jurisdictions continue to evaluate new ways to maximize level-of-service (LOS) in the world of transportation, more and more attention is being paid to multimodal options and analysis. Kittelson & Associates, Inc. (KAI) was proud to contribute to this effort as a subconsultant on the National Cooperative Highway Program (NCHRP) project that developed techniques for evaluating automobile, bicycle, pedestrian, and public transit LOS on urban streets, particularly with regard to interactions among the modes. KAI led the transit aspect of the work.

The project’s techniques are well-suited to “complete streets” and “road diet” evaluations, as users can evaluate the quality of service provided to each mode for any given allocation of the street right-of-way. For example, the trade-offs involved for each mode with converting the space used by a two-way left-turn lane into bicycle lanes or wider sidewalks can be evaluated using these techniques. The LOS scores reported for each mode reflect the actual facility quality perceived by members of the public around the U.S. for a variety of facility types.
