Here is the Naples clearing house, following on from the one set up in Torreón in Mexico. There are many possible approaches for distributing revenues from transport tickets used on several networks, and it is up to the operators to select one.

The task incumbent on us is to design systems capable of applying the rules they have adopted.

The algorithms can be subtle, especially when it comes to allocating season ticket revenues to the various networks: thousands of individual, anonymous data items must be taken into consideration in working out what type of passenger boarded at a given place and time, when and where he made a connection and what his final destination was.

More than ever, our business of designing ticketing solutions requires in-depth knowledge of public transport and information systems. Happy reading!
