I want to build a network dataset to calculate travelling times for busses (service area). I have on shapefile with the streets from my home town, which has a column intitled 'ONEWAY', with values of -1 (to-from), 0, 1 (from-to), but the network is created without the oneway restrictions on those streets. Even if i try a rout, for ex., it is generated without taking in consideration the oneway street. Can anyone help me understand why or what i could do
