Studies: Ride-sharing apps making traffic worse

SF Gate -Ride-hailing companies once promised that their services would reduce the number of cars clogging city streets. In fact, the opposite is true in dense parts of cities.

Everyone knows that ride-hailing apps have undoubtedly benefited customers, making hailing a ride easier and significantly cheaper than taxi cabs.

But are the benefits worth the long-term disruption created by Uber, Lyft and other transportation network companies in San Francisco? Here's what recent studies tell us.

Uber and Lyft accounted for two-thirds of a 62 percent increase in congestion in San Francisco over six years, according to a study published last week. Without ride-hailing services operating, traffic models estimate that hours of delay would have increased by 22 percent.

Uber and Lyft discounted the data Transportation Authority officials released, saying that it didn't account for the growth in tourism, freight or delivery services that increased with the economic recovery.

During periods of high demand for rides with a limited supply of cars, Uber and Lyft raise their prices dramatically — doubling or tripling them, for example, on New Year's Eve. A 2016 Uber and University of Chicago, Booth School of Business, study that tried to make the case that surge pricing was beneficial to customers noted that surge pricing coincided with a doubling of drivers on the road.
