I often notice that there are yellow or black straps attached to the rear doors that open inwards on certain bus types. Can someone tell me why they are needed? Is it a safety precaution or are there any other reasons?
Thanks.

It's a safety precaution to make sure no-one is in the way of them as they open, definitely, but there may be some other reasons I'm missing. It's mainly older Metroline and London United buses with these straps.

Stagecoach's Tridents don't have these straps. I prefer it without them as I can stand right next to the door meaning just the extra two people can get on.

It was invented/idea by a Metroline driver some years ago

It's mainly older Metroline and London United buses with these straps. That's spot on. They're designed to show the swept area of the door leaf as it opens inwards. In theory it stops people standing where the door would clonk someone as it opened. As the door spec changed to sliding doors at the centre door the straps are no longer needed. Also several operators never adopted them - the VLAs on the 123 don't have them. The most famous instance of doors hitting people was with the very first design of DLR units where the doors opened inwards. Despite having different colours on the floor to show where not to stand people were regularly hit by the doors as the DLR became very busy very quickly. I don't have a photo of those trains with the doors open but here's one showing a train close up - you can see there are no runners for the doors to slide along. 
DLR unit 19 at Heron Quays by plcd1, on Flickr We also have the same problem with the rear door on the NB4L where people get hit by it and also people get their feet trapped / pinched as the door opens. This is undoubtedly why TfL are changing the rear door design. |
