In this IDDRI paper, Brimont et al. examine how public authorities can work with “collaborative mobility actors” (also known as carsharing firms) to reduce the environmental and financial costs of private vehicle travel.

In particular, the authors highlight the potential of collaborative mobility actors to reduce dependence on cars in suburban and rural areas, where public transport is often lacking and the dispersion of living spaces (home, workplace, school, shops, etc.) limits the options of walking or cycling. To counter these challenges and promote collaborative mobility in less densely populated areas, as well as in cities, the study suggest public authorities should focus on “six pillars.” These include:

  • Communication with users
  • Fiscal framework clarification and financial incentives
  • Road system planning with better integration of shared car uses
  • Effective experimentation and evaluation
  • Adapting mobility governance
  • Public financing for collaborative mobility
