I've seen that video clip and it does appear that taking the railings down is a sensible idea in principle but I don't think just taking the railings down here without some other improvements to the crossing point is the right thing to do.

This is quite a tiny island in the middle of a very busy junction.

Some of the pictures show nicely designed crossing points with wider spaces for pedestrians to wait.

This whole corner needs some serious looking at but I wouldn't hold my breath.
