The number of cars on the street at the airport pickup and dropoff areas is pretty sad given that at the real LAX, you will always be in a traffic jam. Is there any way to increase traffic in that area alone?

You could use this mod to increase the number of peds and traffic.

There's a mod on this site that increases traffic and and planes, and also changes ads and billboards and such to reflect the real LAX

I have used that mod before, and It seems that it messes with the "Cops back on the beat" mod. It does not remove the cops driving around but it removes the cops walking around the city.
