Shared mobility, electrification and autonomous vehicles are bringing big changes in:
• Transportation supply
• Transportation demand
Need for rigorous research and impartial policy analysis to understand the impacts of these revolutions, and guide industry investments and government decision-making.

Future Mobility:
“Heaven” or “Hell” ?
✓Cars are all electric
✓Energy mix is clean
✓Increased capacity of transportation
✓Better livability in cities
✓Integration with public transit
✓Everybody shares intelligent vehicles
✓Increased congestion
✓Electricity produced with coal
✓Increased travel demand
✓More car-dependence of society
✓Reduced role of transit
✓“Ghost” vehicles traveling on streets

Changes in the Use of Shared Mobility
Changes from 2015 to 2018:
• Carsharing use little changed over the past few years
• Sharp increase in ridehailing use
• Shared ridehailing (e.g. UberPOOL) now a common presence in big cities
• Appearance of micromobility (dockless bikesharing and e-scooter sharing)

Some Conclusions…
• Shared mobility options are getting rapidly adopted in California (and other places), even if they still account for a relatively small mode share
• Users predominantly include young, well-educated urban residents
• Use of Uber/Lyft often replaces use of private vehicles and taxis, but to a certain extent also use of public transit and active modes
• Pooling is (in theory) a good option – but (in practice) it often strongly competes with non-car modes in denser urban cores
• Medium-term impacts on car ownership are largely unclear: how many users might give up private vehicle ownership?

Next Steps…
• Longitudinal analysis of changes in vehicle ownership associated with adoption of shared mobility
• Mobility as a Service (MaaS) likely to affect future car ownership
– Under what conditions individuals prefer to access a vehicle when needed rather than owning one?
– To date, only a minority (mainly in urban areas) seems interested in not owning a vehicle and accessing a suite of mobility services when needed
• New study examining willingness to join MaaS
• New study focusing on airport access

Policy Implications
• Need to focus on human beings and not cars
• Future of mobility will depend on how the market is regulated (and priced)
• TNC drivers’ activity already compatible with EV range and performance (but need to remove barriers!)
• Need for behavioral nudge to support shift towards increased sustainability
• Land use and pricing will be key factors to promote more sustainable choices
• Micromobility provides critical mass for bicycling infrastructure
• Potential of MaaS to modify relationships with private vehicle ownership
