Ah, thanks for posting that screenie. I went in to RH this morning and fixed up those stairs to prevent traffic buildups.
Bridgeport actually runs quite well if you remove the ropes for Bouncers and just let anyone in to any clubs. I also removed the NPC doors in apartments and replaced them with decorative doors instead as my mixologists were spawning inside fake apartments but for some reason were unable to get out ( don't ask me why, it seems ridiculous that they couldn't open a door )
I also use a mod to reduce the amount of ambient traffic in BP, and went into each building looking for trouble spots, such as too tight 1 tile walkways, awkward furniture layouts, and any other areas that were likely to cause routing issues.
It can be a time consuming process, but if you save the game while in Edit Town, and use that as your base save, you'll only ever have to do it once.
I found it worth it to be able to play there with little lag from stuck sims.
