Calypso: an on-the-field demonstrated interoperability scheme

Calypso is largely and globally deployed in very different contexts and countries. A common point is that most implementations require a full interoperability between different authorities in a shared area of public transport offer, at whatever level: local, regional, national.

Calypso has successfully implemented these full interoperable schemes, where cards, tariffs, sometimes customer relationship management, are shared by transport operators, which means seamless payment and access to transport for the users. Below are some examples:

  • Belgium, where the four transport operators (STIB, SNCB, Delijn, TEC) have built together a common ticketing system based on Calypso,
  • Paris region, where RATP, SNCF and all other bus operators, under the authority of the STIF (Paris mass transit authority), offer a common ticketing system to their customers,
  • Lisbon region, where OTLIS company regroups all (11) transport operators of the Lisbon area on a same Calypso system,
  • Grand Montreal area, with 20 operators sharing the same Calypso ticketing system.
  • French Rhone Alpes region, with 32 operators and authorities,

More, Calypso is able to provide an international interoperability solution through the Hoplink scheme, designed in the European project of this name.

Basically, Hoplink is a scheme of interoperability whose main characteristic is its simplicity, answering to two main needs:

  • Interoperability between two different tariff areas (2 regions for example) for regular users,
  • Interoperability for occasional users who spend a few days in a city or a region.

The principle is to share, in a same Calypso portable object, the local ticketing application with a Hoplink application, which is shared between all the operators who join Hoplink: it means interoperability of media and not of tariff or commercial. Consequently it requires absolutely no clearing system, and is easy to implement.
