the route-query tool is infinitly helpfull. if you have a traffic mess near a certain area, you can use it to see how people get to and from buildings in that area. then you can put mass-transit stops near their homes or businesses.

the public parking lots are great. stick one near your residential suburbs, and then put a subway and/or bus stop next to the public parking lot. people will drive to the parking lot, then ride mass transit to work. make sure you've got bus stops or subway stations within 5-8 squares of everything downtown.

Or, go for broke. replace your downtown roads with a monorail.

the most frustrating thing though, is when you've played for a few hours developing some high-proffit slums to feed your massive industrial park in the town in the next region over, and the power goes out. and since the power is out, you cant play your PBW turn that is due, because even though the laptop with SE4 on it has a battery, the wireless network you were using is also affected by the power outage and you cant get to PBW.
