I witnessed a pensioner go arse over head the other day due to a bus they had just gotten on moving away without warning before they had managed to sit down properly. With a warning message they might have had time to grab a hold of one of the poles on board to steady themselves as they took a seat.
I feel like a more reliable way of stopping the pensioner going arse over head might have been if the driver had waited for them to sit down before starting.
If you must use a warning message, make it brief. “Please hold on, the bus is about to move” is unnecessarily wordy. All you need is “please hold tight” or similar. And it had better play when the bus is
actually about to move, rather than twenty seconds after stopping, or after the bus has actually started moving. Maybe wiring it up so it plays when the driver closes the doors is a good shout.
There’s a reason “Mind the Gap” is seen as a cute foible of London’s underground network, rather than an irritating annoyance. It’s brief, it gets to the point.
One of the reasons for iBus’s success has been its clarity of messaging: no unnecessary ‘the next stop is,’ no ‘we will be running via X, Y, Z.’ It’s short and sweet. “139 to Waterloo.” “Bishopsgate.” “Aldwych, Somerset House—alight here for King’s College.”
This has gradually been polluted over the years, including with the “caution: there is a cycle lane behind this bus stop, use the crossing point” (which is solely there to appease St. Thomas’s Hospital.) And now it’s getting worse. The encouragement will be for passengers to turn their music up, and tune out the announcements - which means they’re more likely to miss “the destination of the bus has changed,” or “this is an emergency, please leave the bus.”
