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.
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.
In the early ages of the mobile Internet, routing apps appeared as a viable tool for the few motorists equipped with an in-vehicle navigation system or an aftermarket navigation device. With market penetration increasing, and recent market consolidation, a few companies are now the sole providers of driving directions to the majority of the US population.

One of the major concerns for the technical implementation of a RUC is the ability to collect the mileage of motorists in a way that preserves and protects individual privacy. With the widespread use of connected devices/smartphones and the growth of connected vehicles and the existence of toll tag readers, it is possible to build and deploy architectures capable of computing advanced fee structures (based upon on mileage, road type, time of day, and speed, among other features) that respect motorist privacy.
