Endless stream of vehicles

At my airport, I’m constantly getting a large stream of vehicles (Mostly taxi’s and cars) going to a drop off spot, but not actually dropping someone off or picking someone up. It sometimes causes huge traffic jams, with passengers being late, causing delays. Is there a way to fix this?

Yea, I get the same, adding more roads to try and alleviate the problem doesn’t help, it just spawns more vehicles. It can be a real nuisance I’m sure you’ll agree.

Even when I temporarily closed my airport for construction, I still got a lot of vehicles going to the airport without any reason.
