That’s a good question! Again, speaking only from what I have seen in Beta Let’s plays (watched all of them);
I believe cargo travels to every connected destination as long as there is a demand for that specific cargo and the time of travel is “acceptable”. This is why if you have an oil source right next to an oil refinery the oil will walk there since the time of travel is short enough. How the acceptable time is calculated I cannot yet say. Over time, the cargo production increases to meet demand.
Hope it helps and that I am correct. A few more hours and we will know for sure! 🙂
