In earlier installments of the series, it was always important that the AI finds you and you tended to build your station close to the main routes of the AI in the sector you have been in.
However, this is different in Rebirth. There is no such stream of ships like in previous X Games, they are either around stations or inside the highways. You can basically just exit the highway anywhere where it is empty and build a station if you like.
But, will the AI actually find your station? What are the "rules" here to make sure the AI Traders find and use your station?
