I'm interested in knowing how people, who home grow their Traveller
Universe, impose trade routes?

I see it as mainly two variable system. Better starports promote trade
between each other so a pair of systems which both have class 'A' star
ports are more likely to have trade than two systems with class 'E' or
'D' starports. Shorter distances promote trade so two systems
separated by jump-1 are more likely to trade than two systems jump-4
apart.

I ask because I'm trying to automate at least part of the trade
network/pattern/graph in my sector generator and I don't have trade
classification done yet. After I get trade classification, I'll
probably revisit this so that profitable routes get re-ranked higher
in the order. For my purposes doing the "obvious" part of the job will
be enough as a I expect to add a tool that will allow editing the
available trade routes.
