Adding Turns to Network Dataset

CraigSteverango — Wed, 24 Nov 2010 19:32:42 GMT

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.

Thanks,
Craig.

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

Hi Stevy3

How do you create a turn file?

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.

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.
