RUF:Mi – die Mobilitäts-App für Mittelkärnten! Sei mobil in deiner Region und buche Fahrten bequem per App. Was ist RUF:Mi ? RUF:Mi ist ein bedarfsorientierter Rufbus, der den bestehenden Linienverkehr ergänzt und besonders in weniger dicht besiedelten Regionen eine flexible, umweltfreundliche und effiziente Mobilitätslösung bietet. Die Fahrten erfolgen nur nach vorheriger Buchung, wodurch unnötige Leerfahrten vermieden und Betriebskosten gesenkt werden. Zwei der eingesetzten Fahrzeuge sind übrigens elektrisch betrieben und werden am Betriebshof mit dem selbst produziertem Strom aus der Photovoltaikanlage geladen. Die Fahrzeugflotte beinhaltet des Weiteren auch einen rollstuhlgerechten Minibus, welcher auf Vorbestellung (mindesten am Vortag) und Verfügbarkeit für einen barrierefreien Transport gebucht werden kann! Ein Modell mit Zukunft Seit 2018 – damals noch als Althofen Mobil – bringt RUF:Mi flexible Mobilität aufs Land. Umgesetzt wird das Projekt gemeinsam von der Hofstätter Touristik GmbH, Kärnten Bus GmbH und dem Verkehrsverbund Kärnten (VKG). Was als Pilotprojekt begann, ist heute eine Erfolgsgeschichte – und wächst stetig weiter. Mit der Erweiterung nach Friesach setzt RUF:Mi ein starkes Zeichen für nachhaltige Mobilität, soziale Teilhabe und smarte Infrastruktur – genau dort, wo sie am dringendsten gebraucht wird: im ländlichen Raum. Warum RUF:Mi ? · On-Demand statt Fahrplan: Der Bus kommt, wenn du ihn brauchst. · Nachhaltig: Weniger Leerfahrten, zwei E-Fahrzeuge im Einsatz · Regional gedacht, modern gemacht: Verbindet Orte, Menschen und Möglichkeiten · Zielgenau: Zur Schule, zum Arzt, zum Einkauf oder Bahnhof
