The City of Los Angeles's controversial "road diet" plan, which narrowed Rowena Avenue in Silver Lake from four to three lanes in 2013, has garnered petitions and protests from upset residents since its inception.

In this op-ed, originally published in the Los Angeles Times, Data Scientists Dave Goodsmith and Ben Van Dyke explain what led them to their conclusion that LA's most controversial road diet has had a positive effect, as well as some of the challenges they faced in analyzing that impact.
