My bus routing problem has been doign my head in. The tools don't seem to quite match what I want to do exactly.
Simply I have 75 schools and 1700 students eligible for School Bus travel. Each student is pickup on the network and transported to their best match school based on age, gender Etc.
I have got a model that can create the routes for individual schools (based on selections on the student and schools layers) however I want buses to be able to transport students going to different schools. This will mean there are less routes overall and improve efficiency.
I have been attempting to use the Order Paris Network Object however when I try and solve it this error is returned (a snippit).

It appears to me that you cannot have the same second order pair for different first order pairs. This is clearly a problem when I am trying to route multiple students to the same schools. Does every Order Pairing need to be unique?
Any ideas? Am I even on the right path?
