We haven't changed anything in the passengers and haven't added any queueing logic, this might eventually come with the seated passengers, but nothing started on that front yet.
The things that might affect how passengers would run into each other are:
- Your Passenger density slider, you might have changed that without realizing it.
- The airport profile might have customized the passenger "Thickness" value, which controls the width of the virtual "corridor" passenger will walk (assuming this was a Walk-in gate ), so the wider the corridor is, the less chance you'll have for passengers to clash into each other.
- Random selection of passengers and random animations will affect this, because not only passengers are randomly selected, but every few seconds, their walking animation is randomly selected from several variations, and the playing speed is *slightly* altered randomly, to make the walking less robotic. This means depending on their sorting order, you might have a boarding where lots of passenger clashed into each other ( because the fastest one caught up with the slower ones ), but another one when this might happen a lot less.
