Ah, I see what you're saying; the gaps between strings of traffic need to be longer as speed increases
Bingo, heavy traffic at speed is a nightmare to cross in, reduce either the speed or volume and it's a lot easier, fortunately on most roads where this is a problem there are decent (lighted) crossings. But it's becoming a bigger and bigger problem around some residential streets used as rat-runs and schools on big roads here.
I'd avoid crossing there if I were you, that sounds really dangerous. You'd fare better a little further down the road where you've better visibility, I expect.
Sadly life doesn't always live up to expectations
I try to as well whenever there are roads like that, not always possible in some cases, and not everybody has the same presence of mind, and I wouldn't necessarily expect kids to think like that, or the elderly or people with mobility problems. Not to mention that expecting the pedestrians to mitigate for poor driving is entirely backwards, it's better to address the driving so that it *is* safe enough to cross there, its the cars imposing the danger, not the choice to cross, It is a perfectly safe place to cross there when traffic is travelling at appropriate speed.
You have the same problems as a cyclist and motorist pulling out of junctions that are placed like that too, bends/poor visibility in both directions, fine when people doing sensible speed but if they are not they can be round the corner and T-boning you in seconds. Suggesting I try and find an alternative junction to pull out of isn't really a viable solution!
But now we're into discussing the minutiae of specific roads, which isn't really productive as this is a general discussion.
