Until now, the "lift substitute" could only be used if an elevator was missing or defective at a station. In future, disabled people, senior citizens, passengers with walking frames, baby carriages or small children will also be able to book the on-call bus if, for example, a long walk would be necessary or if a bus route is very crowded. Another new feature is that the BVG Muva can also be used for direct journeys between bus stops within a radius of five kilometers. The destination no longer necessarily has to be the nearest barrier-free station.
