I have 4 cities in my region a 300k citizens each! I got all avenues in each city and I got very well planned subway systems, I also have highways connecting all 4 cities and each city have an airpoort! =) the commute problem started at 300k in all 4 cities at once and they all got abandonded causing bad economicall problems! whatever I did I couldnt fix it, spent hours and hours reading through simtropolis and other forums trying everything with no result! all cities went bankrupt!! god dammit I play on easy mode! =)))
