I have a network dataset in a file geodatabase for UK. In the turns feature class there are approx 250,000 turns. When I build the network, I get about 800 errors saying: 'The edges of the turn element conflict with existing interior/exterior edges.'
I've investigated some of these errors, and it appears that this error is occuring where there is a dual carriageway that restricts U-Turns (ie will have 4 no u-turns coded) but only 2 of these turns are being built.
I've attached an extract of the attribute table- all 4 turns have different start and end Edge1FID's- but only the 2 highlighted yellow turns are bing built, not the other 2.
Does anyone know why I'm getting this build error?
