Uber And Lyft Are Increasing Traffic Congestion On San Francisco Streets, Study Says

You don't need an academic study to tell you that traffic in San Francisco has gotten a lot worse in the last few years.

But a new paper says traffic generated by Uber and Lyft is responsible for almost two-thirds of the increase in congestion over a six-year period.

The study argues traffic congestion would have increased even without the emergence of Uber and Lyft. But their models show the traffic generated by ride-hailing services greatly increased the amount of congestion seen in San Francisco between 2010 and 2016.

The study has been published in the journal "Science Advances". The authors used congestion data from the traffic-information company Inrix.

San Francisco transportation officials are quick to point out the impact of Uber and Lyft is NOT uniform across the city--for example, the downtown and North Beach areas have turned into traffic nightmares while areas like the Outer Sunset have seen almost no change in traffic congestion.
