Hello, Yosef.  You probably just need to save the output from each chunk separately and then merge them all at the end. ... View more

Do you need to create a network dataset, or could you use the ArcGIS Online Services instead?  The Online Services use authoritative network data.  You get charged a small number of credits per analysis, but it saves you the time and effort of setting up your own network dataset.  Since it sounds like you don't have any street data, this might be a good solution to you. ...

The error message to me indicates that your parameters are out of order.  It must be looking at the value of one of your other parameters which you have accidentally put in the place where the hierarchy setting should go.  Double-check your parameter order, or (maybe easier), use explicit keywords when setting each parameter.  For example, arcpy.GenerateServiceAreas_na(Facilities=PDS1, Break_Values=Break_Values, Break_Units=Break_Units, Network_Dataset=streets, ... I'm using the parameter names as specified in the tool documentation.  You can leave out optional parameters for which you just want the default, and the parameter order doesn't matter. ...

You have to add your own impedance attribute to the network and set up the "evaluators" correctly to calculate the travel time based on the road lengths and the speed limits. Here are some documentation pages that might help you out: - Exercise 1: Creating a network dataset—Help | ArcGIS Desktop  - Understanding network attributes—Help | ArcGIS Desktop  - Types of evaluators used by a network—Help | ArcGIS Desktop  That said, unless you have a compelling reason to create your own network dataset in this manner, you might get better results more quickly by either purchasing a Streetmap Premium network dataset for  your area of interest or using Esri's ArcGIS Online routing services.  The data quality will likely be better, and it saves you a large amount of time in creating and debugging your own network dataset. ...

I'm not sure what you mean by a "pedestrian network configuration file", but have you checked this out: GitHub - Esri/arcgis-osm-editor: ArcGIS Editor for OpenStreetMap is a toolset for GIS users to access and contribute to …  I believe this has tools for creating a network dataset for use with Network Analyst.  You can download the latest release from the "Releases" tab. ...

Hello, Pan.  I wouldn't expect you to run out of memory solving a Route with 1000 stops.  I recommend you talk to Esri Tech Support.  http://support.esri.com/contact-tech-support  They can look at your data, and if they can't resolve the problem, or it proves to be a bug, they can submit a ticket to the Network Analyst development team. ...

Hello, Tory.  This capability is not available out-of-the-box ArcGIS functionality.  However, there is a tool you can download for free from ArcGIS Online that will allow you to do it in ArcMap, Add GTFS to a Network Dataset.  You will need your own street data for your area of interest as well as a GTFS public transit dataset for the transit agency or agencies you care about.  A full set of instructions on how to create your network is included in the download and is also available here. You can get some further ideas and best practices for analyzing public transit in ArcGIS from this Story Map. ... View more

Streetmap Premium is a dataset that contains a routable network as well as a lot of other stuff.  You can use the routable network to calculate the network distance between addresses using the Network Analyst tools (particularly Route or OD Cost Matrix).  The network contains "travel modes" that allow you to switch between different types of travel, such as driving a car, driving a truck, or walking.  It does NOT contain any public transit information, such as buses, with actual schedules. If the Streetmap Premium data suited your needs, but you didn't want to purchase your own copy, you could also use the ArcGIS Online services to calculate the same thing.  The road networks used there are the same data as Streetmap Premium, and you just pay on a per-use basis.  Again, there is no public transit information. If you want to add some more details to your question or ask for further clarification, I can go into further detail. ... View more

Yes, this tool is only available in ArcGIS Pro.  It is not available in ArcMap. Documentation/help for the latest version of ArcMap is available here: ArcMap | ArcGIS for Desktop  Documentation for ArcMap 10.2 is here: ArcGIS Help (10.2, 10.2.1, and 10.2.2)  ... View more

Actually, since you already know the routes between the stops, this sounds like a problem you can solve with linear referencing.  You can use the linear referencing tools, or if you're comfortable with python, you can grab the geometry objects of your stops and routes and use the measureOnLine method. ...

Oh, I see.  So the real question is why your network sometimes isn't building successfully even though it says it is.  Are you getting build errors?  If so, the Build gp tool should return a warning message saying something like "Build succeeded with warnings" and give you a path to a text file containing the list of errors.  It would definitely be worth your investigating this file to see if that gives you any clues.  I'm pretty sure it's possible for the build to succeed but for there to be significant build errors such that most/all of the edges are missing. ...

I can't quite tell from your descriptions what the problem is, but it sounds like a potential bug.  Your best bet would be to report this to Esri Support.  They can investigate the problem and either help you fix your network or file a bug so our development staff can fix the issue. ... View more

Hello, Jeff.  We already have some tools to use GTFS data with ArcGIS, available for download here: http://www.arcgis.com/home/group.html?id=d8e84e82803e4c3690c30f9ef0f960fc  These do not use the Data Interoperability Extension, though. ... View more

The number of network edges/junctions/turns is not available in python, unfortunately.  You could access it via ArcObjects if you were really desperate.  You can also count the number of features in the edge, junction, and turn source feature classes, but this isn't always a one-to-one mapping with the number in the network dataset because of your connectivity policy. What is your ultimate goal in obtaining this information.  Maybe we can come up with a different way to achieve the same thing. ... View more
