The project zeoS4 scales 2zeotwo-free on the road in four dimensions: 1. Modernisation and expansion of the station network: New e-car sharing stations in the zeo area and other municipalities will be realised and existing stations will be modernised. 2. Introduction of disruptive digital services: Digital services provide a new user experience. Interfaces to intermodal mobility apps open up new possibilities. The website is being developed into a platform for participation for citizens: inside, the citizens’ offices to sales and service points. 3. Attracting new target groups through marketing and raising awareness: Social media marketing and pedagogical concepts make young people familiar with carsharing. Citizens: Women can test environmentally friendly mobility offers. 4. Development of a transferable organisational and business model: For the first time, the project will be scientifically accompanied. The wealth of experience is accessible to other projects and regions.
