The driving force behind this move is much the same as the Wrigley renovation project: enhancing revenue streams so they can continue to be competitive. On weeknights the Braves with a 90+ win team were drawing 13 or 14000 per night in a stadium they have no ownership interest in and in which they don't get all the proceeds from the overpriced concessions. They were competitive primarily because other than their poor Uggla and BJ signings they had a talented, mostly young and salary controlled team. They have limited options as far as enhancing revenue. They have the same issues with their TV contract that the Cubs do and for longer. They've chosen to move where the bulk of the ticket buyers are AND where they will have an ownership interest in the stadium and I would imagine in the mixed use development as well. Liberty Media, the ownership group is known for its frugality so they aren't going to spend a great deal of money buying up the blighted area around Turner. Just how much would they have to buy up to secure the area adequately to make it feel safe for fans to go to the park where officially sanctioned parking is limited and ripoff lots and car break ins are apparently a common occurrence? According to sports media here, the City made promises to spend money to encourage development around Turner much as they did when the Georgia Dome was built and nothing was ever done on either front. Granted the Braves are rolling the dice to some extent because as you've pointed out, the traffic in that part of town in my experience is not a great deal better than the downtown connector around gametime, there still is no public transportation, and this is definitely going to alienate a portion of their fanbase.
