Michael: First, I benefited from one of the ESRI Virtual Campus courses on Network Analysis. It contained many scenarios that might overlap with your project, including creating turns. Second, I found it to be a lot of back and forth. Not a one pass exercise. Connectivity of nodes is critical as was the quality of the network, as you mention. I would go after local data. Finally, there are options for almost everything you can think of. So I wouldn’t doubt one that points to a road attribute, like one-way.

I’m aware that ESRI includes one with the purchase of Street Map Premium, but I am questioning it’s accuracy and reliability on a local scale since it spans the entire continent of North America. > > Alternatively, if you’ve created a network data before, I’d be interested in what your workflow was, specifically for creating a turns feature class (a particularly daunting step when you start researching the topic). > > Also, is it possible to set a preference to a certain road attribute when routing?
