In 2017 and 2018, California was severely impacted by a number of devastating wildfires that required thousands of people to evacuate. These evacuations were hampered by poor communication, traffic congestion, and transportation and shelter resource deficiencies. To ensure that all citizens have both transportation and shelter in evacuations, agencies must...
In the past few years, devastating California wildfires have forced more than half a million people to evacuate their homes. In many cases, local government agencies did not have enough resources to transport and shelter all of the evacuees, especially vulnerable populations like the elderly and disabled. Meanwhile those who...

Ride-hailing services like Uber and Lyft are so popular in San Francisco that they have become the single biggest factor behind the city’s increasingly snarled traffic, according to a new report.
Researchers analyzed millions of trips and concluded that the services accounted for more than...
In this study, we present exploratory evidence of how “ridesourcing” services (app-based, on-demand ride services like Uber and Lyft) are used in San Francisco. We explore who uses ridesourcing and for what reasons, how the ridesourcing market compares to that of traditional taxis, and how ridesourcing impacts the use of public transit and overall vehicle travel. In spring 2014, 380 completed intercept surveys were collected from three ridesourcing “hot spots” in San Francisco. We compare survey results with matched-pair taxi trip data and results of a previous taxi user survey. We also...
Shared mobility with pooled rides is the linchpin for leveraging vehicle automation and electrification to reduce congestion and emissions and to create livable urban communities. The sharing of rides is older than horse-and-buggy travel. Recent innovations make sharing easier, more convenient, and more efficient. Innovative mobility services premised on pooling can lower travel costs, mitigate congestion, and reduce greenhouse gas emissions. They also offer travelers more mobility choices between the traditional bookends of auto ownership and public transit. While the realm of...
Shared-use mobilitythe shared use of a vehicle, bicycle or other low-speed modeis an innovative transportation solution that enables users to have short-term access to a transportation mode. In North America, shared-use mobility encompasses the submarkets of carsharing, bikesharing, ridesharing, on-demand ride services, scooter sharing, shuttle services, and other emerging industries. In October 2013, the University of California, Berkeley’s Transportation Sustainability Research Center (TSRC) hosted the inaugural Shared-Use Mobility Summit in San Francisco, California. The summit was a...

The rapid growth of on-demand ride services such as uberX and Lyft, or “ridesourcing,” has prompted debate among policy makers and stakeholders. At present, ridesourcing’s usage and impacts are not well understood. Key questions include: how ridesourcing and traditional taxis compare with respect to trip types, customers, and locations served; whether ridesourcing complements or competes with public transit; and potential impacts on vehicle kilometers traveled. We address these questions using an intercept survey. In spring 2014, 380 complete surveys were collected from three...
On Sunday, January 11, 2015, Professor Susan Shaheen from the University of California, Berkeley and Jeffrey Chernick from RideAmigos led a one-day workshop on the present and future of shared-use mobility at the Transportation Research Board annual meeting in Washington, DC. The workshop featured speakers representing the various shared-use modes, other private sector representatives, and public sector officials, and many topics were discussed.
Some of the highlights included: the role of integrated mobile payment; the need to integrate shared ride services with paratransit to...
