This might be a long shot, but I've had no luck receiving response on the ESRI forums so I thought I would try here as well. I have been working with the information discussed in this thread: http://forums.arcgis.com/threads/760...ions-questions. and so far most of it has proved quite helpful. However I have been noticing something that I cannot figure out. I noticed the problem on a larger scale, so I have provided an example size version of the problem below.
Basically, I've noticed that when I run the directions in Desktop it will give me something to the likes of this:
Begin route Graphic Pick 1 - Graphic Pick 2
1: Start at Graphic Pick 1
2: Go north on Hallway Drive 33.1 ft
3: Turn right to stay on Hallway Drive 39.6 ft
4: Turn left to stay on Hallway Drive 39.9 ft
5: Finish at Graphic Pick 2, on the right Driving distance: 112.6 ft
End of route Graphic Pick 1 - Graphic Pick 2
Each turn is indicated (turn left, turn right, etc).
However, when I return the NA Campus directions, this is just written as "go forward". As you can see from the attached photo, it is definitely not just a straight line. The NA Campus output looks like this:
Begin route Graphic Pick 1 - Graphic Pick 2
1: Start at Graphic Pick 1
2: Go forward through Hallway Drive 112.6 ft
3: Finish at Graphic Pick 2, on the right Walking distance: 112.6 ft
End of route Graphic Pick 1 - Graphic Pick 2
These routes are attributed with a RoadClass value of 10. It appears that if a edge changes the "Name" value, it will return a turn direction, but if the name value is the same (ie. Hallway in this case) it will simply say to go forward, no matter how many turns.
A graphic of the route used here is attached below.
I have been successful in getting other portions of the network to work, but I cannot figure out why this is happening. My network is much too large (university campus exterior and interior walks) to create individual turn features.
I am using ArcGIS 10.1, Network Analyst extension.
Thanks,
Eric
