These lots block bus traffic, while allowing all other forms of transportation to pass. I have always been annoyed by the game's lack of proper bus lines. Sims drive buses around like their own cars, instead of following proper lines. By blocking off side streets to bus traffic to create "bus corridors", and only placing bus stops along the corridors, you can come a step closer to a realistic bus transit grid. Included are versions for road, street, avenue and one-way. Credits to Urban Legend for the Traffic Control Pack, on which these lots are partly based. UPDATE: I had made a very silly mistake in the first version of these lots, that would convert all the cars that entered the lot into pedestrians upon exit. This has now been fixed, and everything should now work as intended. It's very important that everyone who downloaded the first version replaces it with this updated version. I'm very sorry for the inconvenience! Plop cost is $1 (to pay for the paint markings ), there's no bulldoze cost, no maintance cost, and no power or water requirements.
