What factors might affect the accuracy of the RTI system?

Devon is a largely rural county and there are large areas that do not have mobile coverage. As the ticket machines on each bus which transmit the data signals rely on the same communications technology as mobile phones, they can only communicate where they can get a signal.

If there is an emergency which delays your bus, it will take a while for the system to recognise that this has happened. Where possible, there will be a message on the displays, website and app to warn you of any major delays
