Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized travel modes.

Recently, new sources of bicycling activity data have emerged such as Strava, Streetlight, and GPS-enabled bike share systems. These emerging data sources have potential advantages as a complement to traditional count data, and have even been proposed as replacements for such data, since they are collected continuously and for larger portions of local bicycle networks. However, the representativeness of these new data sources has been questioned, and their suitability for producing bicycle volume estimates has yet to be rigorously explored. This project develops a method for evaluating and integrating emerging sources of bicycle activity data with conventional demand data and methods, and applies the results to several locations to predict network-wide bicycle volumes.


  • Familiarity with a method for evaluating and integrating emerging sources of bicycle activity data with conventional methods;
  • An understanding of the limitations and opportunities of new and emerging data sets;
  • Results of a test application of a new method for integrating data from various sources.


This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at Portland State University and the University of Texas at Arlington. The project is supported by a pooled fund grant. Matched by NITC, funding partners include Oregon Department of Transportation, Virginia DOT, Colorado DOT, Central Lane MPO, Portland Bureau of Transportation, District DOT, and Utah DOT.

Joe Broach, Portland State University

Joe Broach is a ​Research Associate with the Transportation Research and Education Center (TREC), an Instructor in the School of Urban Studies and Planning at Portland State University, and a Senior Researcher and Modeler at Metro (MPO). H​is work primarily ​focuses ​on transportation data​, behavior,​ and modeling, and ​he ​helped design the ​Portland region's ​next-generation bicycle model in conjunction with Metro.​


Kate Hyun, University of Texas at Arlington

Dr. Hyun is an assistant professor in the Department of Civil Engineering at UT Arlington.  Her research centers on big data analytics using Intelligent Transportation Systems technologies for various applications including community mobility modeling, traffic monitoring and operation, freight transportation planning, safety, and travel behavior study. In recent five years, she served as the PI or co-PI over 20 interdisciplinary projects. She seeks to explore how professionals in different fields could interact around issues of transportation and transportation equity and to identify opportunities for enhanced collaboration and training in anticipation of emerging transportation needs for disadvantaged communities.


This 60-minute webinar is eligible for 1 hour of professional development credit for AICP (see our provider summary). We provide an electronic attendance certificate for other types of certification maintenance.

This webinar is hosted by the Transportation Research and Education Center (TREC) at Portland State University. The research was funded by the Summit Foundation and the National Institute for Transportation and Communities (NITC), a program of TREC and one of five U.S. Department of Transportation national university transportation centers. The NITC program is a Portland State-led partnership with the University of Oregon, Oregon Institute of Technology, University of Utah and new partners University of Arizona and University of Texas at Arlington. We pursue our theme — improving mobility of people and goods to build strong communities — through research, education and technology transfer.
