Real Time travel Info is rubbish

Bus travel is not a problem, the issue is the so called real time info displayed at bus stops, bus stations etc. The displays show phantom buses, or display that a bus is due that never turns up or the information disappears from the display at the last minute with no bus appearing. If the display showed a bus was cancelled it would be a lesser issue as people could then plan. This sometimes means people miss an alternative bus due to lack of time to get to another bus stop.
