In response to the global pandemic, in person activities are restricted on the PSU campus. Until further notice, all live events hosted by TREC will be online only.

Friday Transportation Seminars at Portland State University have been a tradition since 2000. You can join us online at 11:30 AM. 



Neighborhoods of color tend to be the most dangerous places for cyclists and other road users, a result in part of historic disinvestment and failure to provide basic infrastructure. Safety efforts to reduce crashes, like Vision Zero, have called for both increased investment, a qualified benefit for disenfranchised communities, and increased traffic enforcement, a response that is likely to place people of color in even greater harm based on extensively documented police injustice.

To what extent, then, do poor cycling conditions and inadequate infrastructure contribute to disparities in policing in Black and Brown neighborhoods? Using data obtained from the Chicago Police Department, I will present findings that show how street characteristics, cycling infrastructure, and neighborhood characteristics are associated with the number of citations issued for riding a bicycle on the sidewalk over the previous five years. I find evidence that fewer tickets are issued on lower-volume streets and on streets where bike facilities are provided. While the provision of bike lanes and paths do not eliminate racial disparities in policing, they do contribute to more comfortable cycling conditions and lower odds of getting a citation. I will end with a discussion how the findings inform planning and policy.


  • Participants will learn about the role of policing in bicycle safety planning in the U.S. and the issues associated with it.
  • Participants will learn how bicycle citations are distributed by neighborhood in Chicago.
  • Participants will understand how inadequate transportation infrastructure contributes to inequitable policing for cyclists.

Jesus M. Barajas is an Assistant Professor in the Department of Environmental Science and Policy and affiliated faculty with the Institute of Transportation Studies at UC Davis. His research focuses on mobility justice and transportation equity. His work examines the role that planning and policy contribute to access to opportunity among historically marginalized populations, with a goal of informing policy agendas that remedy injustices. He holds a PhD in City and Regional Planning from UC Berkeley.
