Turns in Network Dataset: Build Error

AnnaMerren — Wed, 16 Nov 2011 08:09:22 GMT

Hi,

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?

Thanks
Anna

See the section "Properly Defined Turns" here:
http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00470000000p000000.htm

It may describe the sitution you have as to why some turns are not getting created.
