A new mathematic algorithm that can predict commuter train delays up to two hours in the future has been developed in Stockholm, Sweden, by the city’s commuter train operator, Stockholmstag, and mathematician Wilhelm Landerholm.
The ‘commuter prognosis’ uses big data to visualise the entire commuter train system two hours into the future, simultaneously calculating how the delay affects other trains in the system and automatically providing the information to traffic control centres, enabling them to in
