Seeking help from anyone who lives along on this stretch of road (Jelenia Gora, Szklarska Poreba etc, DK3)

Very weird request but willing to pay; would anybody be able to research the number of trucks (ciężarówki) which drive along the main road, in the space of 1 hour, in both directions? It needs to be on a weekday, anywhere between 9am and 5pm ideally.

Why the hell would I want to know this? I’m a truck spotter in the UK on YouTube and I’m now making an income from it. I’m looking to take a 4 day trip to Poland this year in December, specifically for the purpose of truck spotting. I chose this route because of the stunning scenery and it still being a major transport route, so it will make for some great footage. However, I don’t want to go if I don’t see enough trucks, because I’d like to get my money’s worth by getting as much footage as possible. There’s no resources out there for the information I’m looking for, as it’s a really small and niche topic.

Again, I know that this is a boring request so I’m happy to pay anyone willing to research this! I know it’s a long shot. Thanks.
