The document discusses the collaborative economy and how it is changing mobility. The collaborative economy is defined as business models and practices based on horizontal networks and community participation that transform how people live, work and create. Examples of how this is changing mobility include carsharing between individuals and companies, long-distance ridesharing, and on-demand ridesharing through apps. Multi-modal transport apps are also integrating different transportation options like public transit, carsharing, and ridesharing. Cities are starting to build their own multi-modal transportation systems to support these collaborative and sharing-based mobility solutions.
