Yes, that is the spot. There is a safe bridge that takes you over the road or a much safer place to cross after the bridge. The barriers are there as their is a train station above the bridge and thd pavements get pretty crowded at times. You didn't answer my question about Children btw.
I'm not sure why I need to condone or not condone anything. People will cross where they want, and long may it remain so. If the "official" crossing point is also the most direct and convenient, they will use it. If it isn't the best way to get where they are going, they won't. That's all that matters, really. The roundabout and its approaches seem to have rather a lot of pedestrian-unfriendly features - those big round cobblestones are clearly intended to stop people walking there. I'd be pleased if my kids, or kids known to me, felt free to explore their environment under their own steam, and would focus my efforts on stopping people feeling entitled to run them over for doing so. People always have an exaggerated sense of fear for their own children, of course, and if I were shepherding a child across that road, on a bike or otherwise, I probably wouldn't do it quite like that, but there we are...
