I'm in my 50s. This is not something that I have ever encountered in the street.
Perhaps, when walking through a park or similar, when I was in my teens or twenties, some kids might have kicked a ball in my direction a couple of times, with the hope/expectation that I would return it, but that it about as close as I have experienced.
There are some details here and here. I'd expect that reaching out the project team themselves would be the next step. I'd expect that they will have a management plan and project summary of some kind that they could share at the very least.
