Limiting eternal commuters

[High5Tower]

I have been working hard to controll the numbers of eternal  commuters.
I use the example in the CAM manual to set which cities get access and its incredible how crafty these sims are at finding a way out of town. I will stop all roads,subways, rail from connecting but they still find a way.
The one thing I have the worst luck at are the sims that will come into town (in this exmaple) on a train, find a bus and head north west and then jump on a subway and head south and then find a train and jump on heading out of town. And I just bet they are just laughing all the way! No work for us! 
So I sermise that sims just really don't like to work if they can find a free ride.

One sure way of doing it, is to have roads radiating out from downtown, but never connect any suburbs with ringroads.
The only exception would be railroads, which I restrict to being used only by freight trains (don't build passenger stations).

There are several other layouts though.

Two large and two medium sized cities:


A mixture of nine large cities and 112 small cities:

hello - i'm trying something new:  looking for information before asking a question - that's how i found this post.  can you point me in the direction of those other layouts you mentioned that will help fight pesky little eternal commuters?  i created a region based on the nine large cities above, but i'm not exactly loving it.  wonder if there are other examples out there, cause i'm horrible at this kind of thing.  thanks, DeeCee
