New Study Underway: Do Ride-Hailing Services Reduce Car Ownership?
In a Sacramento Bee opinion on September 3, Amanda M. Eaken of the Urban Solutions program at the Natural Resources Defense Council and Susan Shaheen of the Transportation Sustainability Research Center at U.C. Berkeley made a case for including ride-share and similar mobility options in required (SB 350) strategies in California to reduce greenhouse gas emissions.
However, they conclude that "much more research is needed to fully understand shared mobility’s social and environmental impact, and important policy challenges remain to ensure public safety and resolve issues around insurance and fair labor practices."
"Shaheen said the study will include two key components: activity data from Uber and Lyft; and a survey of rideshare users," writes Andrew J . Hawkins for The Verge. "The survey will gather impressions of users about ride-hailing, their socioeconomic data, as well as 'what they were doing before and how they would have taken the trip otherwise,' Shaheen explained."
We don't yet understand what impact Uber and Lyft are having on our transportation system," Eaken told The Verge. "Some people speculate that they are enabling people to live in cities without owning a car, which both saves them money — average cost to own a car is $9,000 a year — but also we know when people don't own cars they drive less.
On the other hand, some speculate that people are using Uber and Lyft instead of walking, biking, or transit. So there could be a detrimental effect."
(F)or each car-sharing vehicle in use, on average there are nine to 13 fewer cars on the road because members either sell a car or postpone buying one. Households using car-sharing services reduce their monthly transportation costs, and their emissions drop between 34 percent and 41 percent a year, according to a UC Berkeley study.
Already in its home city of San Francisco, the UberPool service accounts for nearly half of journeys with Uber and is profitable one year after it was launched. Mr Kalanick was referring to shared-taxi services, the latest battleground between Uber and its rivals such as Lyft and China's Didi Kuaidi.
Eaken and Shaheen also described it in their Bee opinion:
One innovative and popular technology is “ride-splitting” – matching passengers traveling along the same route to split rides and their cost. By connecting people in real time to split rides, these services could provide an alternative to single-occupant vehicle driving.
We look forward to seeing data to verify that ride-hail is indeed good for the environment, just as it is for traffic safety. Hopefully the NRDC/U.C. Berkeley report will also include the land use aspect of reducing required parking spaces as well—be it for residences or businesses.
