The EcoBus service was a pilot project operating in the rural area of Bad Gandersheim from June until August 2018. It combined different routes with similar starts and destinations calculated by an algorithm. Passengers could request door to door rides within an area of 100 km², which comprised the railway hub of Kreiensen, thus ensuring good connections with longer-distant means of transport. The population served was around 14.000 inhabitants, with an average of 4 buses operating simultaneously, and with operating hours (daily 8 AM until 11 PM, Mon – Fri starting at 6 AM, Fri and Sat nights until 2 AM next day) that covered different mobility needs. The price was the same as for scheduled public line service and tickets for EcoBus were integrated with those for scheduled bus and train service. Booking was managed via app, internet or telephone, ensuring to be easily accessible by different target groups. Reservations could be made for spontaneous requests or hours ahead for the same day. The routes were calculated in real time so that the passenger received a confirmation only after a few seconds.
