GVB, the public transport operator for the Amsterdam region, wanted to raise the provision of information about planned and unplanned public transport disruptions to a higher level and launched a tender. CoolProfs won the tender with its proposal and developed the RivierA (Passenger Information Improved In And Around Amsterdam) information system together with GVB. This system enables the transport company to provide passengers with up-to-date information about faults in a fast and automated manner. This information can also be distributed via various information channels. CoolProfs developed a similar system for Rotterdam-based public transport operator RET and for The Hague-based public transport operator HTM.
