Can't seem to find answers to these questions but here goes. 1. What do I do about traffic/road pollution? I have tons of parks, anti-pollution buildings and trees that line just about every major road, but I'm still getting pink and orange pollution on the heavier roads. These are hot spots that have subways and bus stops all over the place but I can't seem to curb the air pollution on roads. 2. CO$$$, CS$$$, and R$$$ demand. I'm not sure how to get the value up for these guys. They are about the only types of high demands I have in my city right now. (actually everything else is negative.) I have tons of parks, school, health, etc in the city, no problems with fire or crime. Everything seems pretty solid but I have empty zones that won't fill because of this. The city is about 1.6million, in a region with 2.5 million. 3. Airports I have a few custom airports in my landmarks menu and when I place them they act dumb. Basically they don't seem to work and relieve demand needed that the vanilla airports provide. Am I missing a plugin or are they just eye candy? 4. World Trade Center Towers Plop. The world trade center towers lot has something like 55k CO$$$ jobs. The lot has become abandoned due to 'demand.' But as mentioned above I have tons of demand in my city for those jobs. Residential lots are near by so commutes shouldn't be an issue. Will a lot like this fill back up eventually, or is it pretty much taking up lots now? 4a. Anyone know if this lot will be transit enabled (if that is the right term.) There is an avenue on the lot that no matter how you line it up will not let you connect another avenue to it. 5. Missing lot hints. Any clues on identifying which lot files are what when only texture files show up. I have a few lots that are obviously tall buildings that vanish when the construction is over and turn into a texture lot file with no building, no brown box, no query info. When I try to query it, it tells me 'Zoned Commercial' or Zoned Industrial. Not really helpful. plus I can't bulldoze them. (I think this happened when I used the cleanitol tool which messed up more than it helped, if any.) 6. Large lot crime. I have several modds for crime and such, but there are still problems at airports, country clubs and universities. Any modds out there that extend police coverage in tiles? Yes I have roads around all the buildings. Thanks for the help and suggestions.
