Uber, Lyft cars have heavy impact on SF streets, study finds
SF Gate - 06/13/2017
San Francisco officials want to gauge Uber’s and Lyft’s impact on the city. That’s why the transportation authority, which is distinct from the San Francisco Municipal Transportation Agency, produced the report. It was based on data collected from the companies’ apps by Northeastern University researchers over a six-week period late last year.
Researchers at Northeastern University divided the city into 200 sections and used software to activate the Uber and Lyft apps every five seconds, which returned information on where vehicles were located. By observing changes in the supply of vehicles, researchers determined when drivers dropped off or picked up passengers, and started or ended a shift. The researchers said the activity did not affect drivers or riders. The County Transportation Authority cleaned and analyzed the data.
