This chapter focuses on strategies to initiate a shift in mobility behaviour away from private cars towards a combination of more environmentally friendly transport modes including public transport, ride- and car sharing or even completely carbon-free modes like walking and cycling. The requirement for such a shift is that people must be able to actually choose between different travelling options and combine them within an intermodal mobility network. Here, shared mobility has a considerable potential to fill the gap between public and individual transport options.

This chapter summarises results from different studies on shared mobility from the providers’, the users’ and the political perspective. The user’s perspective is based on an empirical study comparing car sharers’, car drivers’ and public transport users’ attitudes and mobility patterns.

The empirical findings from the case study have shown that shuttle trips by car in general, and to the train station in particular, are an important field of action for improving the environmental impact of intermodal trips. The study has also shown that car sharing enables people to live without a private car by using different transport modes for different purposes. As the majority of car sharers report needing a car only one to three times a month, they have a very small carbon footprint compared to the average car owner.

Mobility patterns are determined by local transport options as well as by personal routines. Hence, current changes due to new shared mobility options seem to have a considerable direct impact on how people organise their daily lives on the one hand and an indirect impact on their living costs on the other hand, since private cars have an important share of private household costs.

From an environmental perspective, any incentives to encourage people to choose alternative forms of transport over their private cars would seem to be particularly effective. Thus, understanding the behaviour and needs of multi- and intermodal travellers is an important step towards sustainable mobility. Acknowledging that most travellers still need a car every now and then, car sharing is an essential addition to public transport systems, supporting both public transport use and carbon-free mobility like walking and cycling.
