A future of shared mobility

Shared mobility is transforming the way we move around in cities and is challenging consolidated transport modes such as the private car, taxi and public transit. While shared mobility has an immense potential to improve the efficiency of personal transport and, hence, reduce emissions, this paper makes the case that shared mobility per se is not sufficient to achieve this important goal. Rather, shared mobility services should be designed and integrated with other transport modes having carbon emission reduction as an explicit optimisation goal. This observation prompts a call for the development of accurate models and analytical tools for the estimation of the city-level benefits of different forms of shared mobility, and of their integration. Examples of these tools are briefly reviewed and discussed in this paper.
