A new fare model in just five months

One single fare for Westphalia-Lippe: Thanks to the “WestfalenTarif” fare, passengers only need one ticket for the entire region. When the idea of a joint fare system within the zone of the local transport association (Zweckverband Nahverkehr Westfalen-Lippe, NWL) arose in 2011, this was particularly relevant to WVG. The company had already been using IVU solutions for all its transport areas for a considerable amount of time. Now, the priority was to ensure a smooth transfer to the new fare model.

In order to be able to offer the new tickets to all passengers as a standard, it was particularly important for WVG to provide all their companies with new data in good time for the start of the WestfalenTarif. As well as the central background system, this also affected all sales devices, from the on-board computer to handheld devices and e-ticket validators. In the process, it was important to intervene in the existing installation as little as possible, in order to avoid disruptions to the normal course of operations.

The standardised structure of the IVU solution also helped during this process: The central IVU.fare background system manages and prepares all fare data and then transfers it to the hardware equipped with the IVU.ticket ticketing software. In order to implement the requirements of the WestfalenTarif during normal operation, IVU developed a series of solutions that enabled WVG to have a virtually trouble-free transfer. This allowed WVG to forgo a special update, and downtime was minimised.

Within the five month period between the final fare definition and the launch on 1 August 2017, IVU prepared all WVG companies for the WestfalenTarif. In total, IVU updated the software on around 850 on-board computers and mobile handheld devices at WVG during this period. By the end of this period, the customers could purchase the new tickets at all sales points, both stationary and mobile.
