Golden Rules - Ticketing for MaaS

Golden Rules - Ticketing for MaaS

Beyond its original function of collecting revenues from transport, ticketing is now considered as the armed wing of Mobility as a Service, known by the acronym of MaaS. Ticketing must enable mobility services to be combined and offer passengers a seamless, end-to-end, easily accessible transport offer.

Yet this new ambition of ticketing will only be achieved if systems are well designed and highly scalable. This is indeed a major challenge: with streams of new requirements flowing in, linked in particular to MaaS, the need for ticketing systems to be flexible has never been so great. Yet ticketing systems, which are sometimes subject to vendor-locking do not always provide the appropriate solutions to this challenge.

The purpose of this document is to highlight best practices to help ticketing systems reach their target qualities and performance, and to be a tool in the hands of transport authorities and operators to implement their mobility policies.
