MIT study finds Uber & Lyft increase congestion, decrease transit ridership and don’t affect vehicle ownership

Green Car Congress

Researchers at MIT report that the entrance of transportation network companies (TNCs)—specifically Uber and Lyft, which together have a 98% share of the market—in cities led to increased road congestion in terms of both intensity (by 0.9%) and duration (by 4.5%); an 8.9% —Diao et al.
