The strangest thing happened

Your path to proper gameplay at this point may be to declare this ongoing game (as it now is) a loss and start over. That could mean a totally fresh start with all new sims or some combination of fresh worlds with sims from the current one extracted by way of the Household Bin in Edit Town replaced elsewhere. Personally I would first want to test the game with all of mods and CC you have in place in a known to be gentle to play world such as Sunset Valley, Riverview, or Twinbrook to rule out content issues that may be extending across all saves. And I would try to avoid particular custom worlds that are already known to cause issues for so many players or that are never going to work properly with Traveler.

What about a Factory Reset?

A factory reset in addition to or instead of starting over in different worlds? A factory reset would remove the custom worlds you are currently playing. If you reinstall them with the intent of playing these saves forward, and the underlying custom worlds themselves are part of the problem, isn't that just going to lead to re-creating the problem soon down the road?

Total Annihilation?

Did you actually clean your saves with something like Kuree's SaveCleaner? I didn't see it mentioned anywhere. I have to do that all the time to avoid error 12's.

Also, travel from town view and don't watch your sims.

The issue may also just lie in the lot where your family lives. The usual stuff, too much stuff in personal inventories, in other storage places, a big garden, etc. My main family is due for a clean-up. If I play a townie family with little stuff, everything's peachy. My travels out of town also take much too long, something like 30 minutes. Coming back is done in about 10 minutes. Which means that the issue is often related to the world you travel from, not necessarily the one you travel to.

Maybe I´m not helpful at all, but how are your option settings?
If I travel to a big world or a world which is in play for a long time, I have to lower all my game options to the minimum, otherwise I´ll get Error 12 when saving right after the travel. And I always prepare my family for travel, then save, quit the game, load it again and travel, like @Turjan already suggested. And traveling lasts longer in saves in which I travel to very old (playwise) towns, sometimes more than 45 min.

If you want to investigate further instead of jumping to abandon the save, you could try starting a new save and then traveling. If that works, you can keep testing to see if specific destinations cause it, but you still might have a major problem in your current save.

Yup. I just cleaned out more than 90 MB of images out of my TravelDB.package yesterday.
