Topics Transport for the North (TfN) has begun to make regional information on travel disruptions available to the Citymapper journey planning app. It has enabled the app to include information on disruptions in bus, tram and ferry services through the Disruptions Messaging Tool (DMT), initially provided by transit data specialist Ito World and, since March of this year, managed by the Department for Transport. Citymapper began using the TfN data in March. It has been supplied to the Moovit travel app since April of last year. It is now being used in Greater Manchester, Liverpool City Region, Sheffield City Region, the Transport North East area and West Yorkshire.
