Gregory D. Erhardt, Sneha Roy, Drew Cooper, Bhargava Sana, Mei Chen, and Joe Castiglione have published the study "Do transportation network companies decrease or increase congestion?"

The study finds that in the city of San Francisco, "TNCs are the biggest contributor to growing traffic congestion in San Francisco."

From the abstract: "Between 2010 and 2016, weekday vehicle hours of delay increased by 62% compared to 22% in a counterfactual 2016 scenario without TNCs."

The study concludes by listing other research that has found similar negative effects on congestion from TNCs.
