Adding Turns to Network Dataset

Hi Everyone,

I have route data with unique identifiers for links on a road network.  I have created a network dataset and created a turn file.  I have another file that contains the unique identifiers for links and the links that they do not allow turns onto (i.e. UID: 7942409 does not allow left turns onto UID 5931616). 

My question is whether there is a way to add this information into the turn feature file used in the network without having to manually edit each turn (there are about 20,000)?  For the turn feature file, you need to know the edges and not the id's that relate to the original route file.  I have tried reading up on this but can't seem to find a solution.  Any ideas?

Any help would be appreciated.


p.s. the turn file is just a list of uid's and restricted uid's and a time, if necessary.

Hi Jackson,

I answered your other post but thought I would include the comments here as well.

The Turn Feature Class toolset  contains tools used to build and edit  turn data. The tools in the toolset allow  you to create new turn  feature classes, convert existing ArcView or ArcInfo  Workstation turn  tables to turn feature classes, and maintain the integrity of  existing  turn features based on their geometry or an alternate ID field in cases   when the reference source features are updated.

Overview of Turn Feature Class toolset

The Network Analyst tutorial  exercises are a good starting point for  learning ArcGIS Network Analyst. They  provide data, steps, and  conceptual information on how to accomplish specific  goals, such as  building network datasets and performing various network  analyses.
