First go through my answer here: http://gis.stackexchange.com/a/104262/14435. This will let you understand how to create a network dataset. Go though an Esri KB exercise - I recommend this to anyone who starts working with NA. It won't take much time but will give you all the basics you need to create a network dataset on your own (with your own data). Ask ...

You'll need to use Network Analyst for this. The first thing you will need to do is turn your lines into a network. The Network Analyst Tutorial exercise 1 covers this, but be aware it may not go into sufficient depth, as there are geometry and topology considerations to take into account. Why isn't the service layer shape properly spread out? touches on ...

You are describing things that are actually handled in a couple of different ways in the network. First, one way (also known as direction of travel) is handled by a one way attribute for the network edge (the lines). You can get more info about that from my answer at Does OSM data contain the direction of travel? Next, when you talk about modeling ...

Totally crazy how easy the answer is. One doesn't even need to use model builder to iterate through all possible routes. In my case, I have a feature class (points) that represents every doorway at the archaeological site (N=448 doorways). I simply pointed Network Analyst to that feature class for both Facilities and Incidents, while indicating in the ...

It looks like you should be using "Iterate Datasets" instead of "Iterate Files". I can't tell if "Iterate Datasets" requires GDB feature classes or if it will work on your current shapefiles. From esri help: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00400000001n000000.htm "Iterate Files" specifically skips datasets that are ...

Network Analyst solvers only produce temporary results files/layers. If you are running this from the model builder, you need to make sure the results are added to the display. If you are running this from a tool dialog box you need to expose it as a model parameter. See this tutorial and particularly the notes. If you are looking to generate a feature ...

Thanks to everyone for their help and responses and for pointing me in the right direction. When adding new roads to the baseline dataset, the key was creating the new roads and connecting them non only to one another at endpoints but also the original roads features at endpoints as well. Splitting existing roads into new lines with respective new ...

Try taking your Network with the new roads and generate a new road Network out of it. Then swap out the Networks.

That error suggests your GTFS data is missing the (optional per spec IIRC) wheelchair_boarding column. Maybe try adding this column in using Excel / LibreOffice? If that doesn't help, there is a line number in the Python file that should get closer to the issue.

The road goes over the bridge. In either scenario you describe, the network will fail/have gaps there with no connectivity. If the bridge is important, those segments should still be present in the road layer but as their own separate features. In such a case (really any case) you would not want a multipart feature on either end and in between. You either ...

One method is to use Route Analysis. It's not immediately obvious why since Route Analysis only allows you to input one "Stops" feature class instead of two feature classes for origin and destination. However, route analysis will create unique routes for every group of features with the same ID. In other words, route analysis will produce a single, unique ...
