Intermodal Network Construction

[BenKeller2]

I am creating an intermodal network for North America, and have rail, road, intermodal facilities, and nodes for both rail and road. I made sure my connectivity was correct so that the facilities were connected to both rail and road. As of right now my only parameters, that were made by the too not me, are miles and oneway. Are there any others that I should be creating or is that sufficient to start. Unfortunately I do not have a turn class, but my main analysis is basically visualizing where rail cars are leaving the network to travel on road, and where they are returning to rail. Also, I do not need to snap my intermodal facilities to line segments correct? Obviously most facilities span a large distance and are not directly on top of the rail or road. Any extra help or insight would be great.
Here is the intermodal network I am currently using minus the waterways:

Hallo, This clearly indicates, that the previous process of generating transfer lines was not accurate. I advice to follow the previous procedure for a very small simple network. Like the boxes we use for the X|O game. Very very simple game.

Else you could select all the dangles and use extend or trim to let them join properly.

I do not think ArcCatalog does anything unless you command it to do so 🙂

I was able to complete the network and it works very nicely. One thing is that I cannot receive directions because it says my network does not support it. I know you need length fields to support directions, and all of my edge classes in the dataset have a mile attribute and I have it set up as a cost in the attributes as well. Shouldn't there be directions then for me to set up as well? It will not let me click directions in the build process?

You need a string field with street names for directions to work.
