Developer Maxis will be launching update 3.0 for their building simulation title SimCity this week according to a new post on the game's official forums. The patch notes include a long list of fixes, varying from pollution changes through to trading fixes that make "gifting more reliable."

Among the changes included in the 3.0 update is a large list of traffic fixes, hopefully to fix the not-so-smart AI. The routing system has been tweaked to offer more information to vehicles through "u-turns, required vehicle stops, and vehicle behavior on certain road types", hoping to make traffic "smarter" in the process. Vehicles will also be able to perform right-hand turns at red lights, improving "some cases of traffic." Fixes to school buses will also be fixed, hopefully eliminating congestion in neighbouring cities.

Trees have also been given an internal boost, now lasting longer but not eliminating as much ground pollution. Continue the pollution changes cities will also be a tad cleaner with sewerage taking "a more direct route to regional sewage plant instead of throughout the city."

Update 3.0 will mark the second major update since the game launched to a rocky start back in early March. For the full patch notes you can check out the forum post over here.
