In ArcGIS Pro, the OD Cost Matrix itself does not have a 1000 origin limit. If you have your own local network dataset then you can solve for larger number of origins. The 1000 Origins limit is imposed when you are using ArcGIS.com to solve this problem. This is a limit imposed on the OD service. How many destinations do you have? If you have a large number of destinations then the size of the computed OD become quite large and hard to transfer that data back. So try to use the splitting it as Dan outlined. Jay Sandhu

Since these streets appear to be restricted for cars, you have to think what is the logical thing for the type of analysis you are doing. So, you can: accept the results, or turn off these restrictions in the service area Analysis settings (it will impact the analysis for all facilities), or move the location to the nearby main road and re-solve.

Did you relocate the facilities after checking on the Exclude restricted portion of the network? Also, have you tried using the Network identify tool to see if the edges there are connected to rest of the network. One other thing you can do is to turn on the service area lines. That is, on the service area layer properties, click on the Line Generation tab and turn on the generate lines option. Re-solve. The returned lines should tell you where they do not connect to rest of the network. (There may be restriction that is on for causing the disconnect). Jay Sandhu

If you are getting a small service area for one location than most likely it is located on an edge that is either restricted to travel on or disconnected from the network for some other reason. What network dataset are you using? You may want to examine the connectivity of the edge with the network identify tool on the NA toolbar. Or, if you are using ArcMap, you can bring up the service area layer properties and on the Network Location tab, at the bottom left, check on the "Exclude restricted portions of the network" and then in the NA window, right-click on the Facilities and choose "Recalculate Location Fields". And then solve again. If the location was on a restricted edge, it will get moved to a nearby un-restricted edge and you may get a better service area. Jay Sandhu

I just want to clarify that Utility Network capabilities in Pro do not have anything to do with Network Analyst or Network Datasets. Utility Networks are for modeling and analyzing networks with flows such as electric networks. Network datasets are for modeling and analyzing transportation networks. The ArcGIS Pro 2.1 release will not have the capability of creating new network datasets with a wizard. There will be more capabilities for viewing the network dataset properties (costs/restrictions) and you can continue to create network datasets with a template from the schema of an existing network dataset.

You can have holes in your service area IF you have roads that cannot be reached within the specified breaks. Unreachable lines can also be due to restrictions such as oneway. You can minimize/eliminate the holes by making sure that on the Polygon generation tab you choose the Generalized option and not the detailed option. You also say that some positions are not correct. Where are these not correct? You can turn on the lines in the Line Generation and choose Split Lines at Breaks and then once the results are created, symbolize each line break value as well. This way you can verify that the lines and polygons match the break values. Jay Sandhu

Within ArcGIS, the Generate Near Table tool is the best way to compute Euclidean distances. The other way would be to script it up in python. You can project the point data to the right projection and then run the Add XY Coordinates tool. Then with the X,Y coordinates, you will have to compute the straight line distance and write it out.

The GP tool in Model Builder does not have access to the map document, so not able to add inset maps into the html output from the Directions tool. (The directions window as you noted, does have access to the map and has those capabilities). Jay Sandhu

Mike, CF is like OD. One difference is that by default it is set to find ONE closest. You need to change it to find the number of locations you have. It will give you all the routes. Look at the TargetFacilityCount parameter when you are doing the make CF layer. Closest facility analysis—Help | ArcGIS Desktop Jay Sandhu

What are you trying to achieve? Are you trying to get a distance matrix for all points that you have? In that case the route solver is the wrong approach. It will only solve the routes for stop pairs loaded with the same ROUTENAME property, which I think in your case is stop A to stop A and then then Stop B to Stop B, etc. It is not going to solve Stop A to Stop B, unless you load that pair as well. So if you want all pairs, use the OD Cost Matrix and load your locations as origins and destinations and solve. It will solve and give you a complete matrix of travel times. But it only computes a straight line route shape (for speed). And in case you need the actual route geometry of the shortest paths, then use the Closest Facility solver. Jay Sandhu

You say buses are in the middle of the road. What does that mean? The reason you are getting a small polygon is because your facility is located on a non-traversable edge (as reported in the warning). THIS means that the edge on which you placed your facility is NOT connected to any other edge. So you are getting a buffer along the road edge on which you placed the facility. Reducing the number of edges will not do anything. You have to fix your data. Looking at the included picture I see the word "OSM". So I am assuming you are using Open Streetmap data. Did you create the network dataset with Anyvertex connectivity as OSM data is not the default edge connectivity? I will suggest that you use the OSM toolbox to create the network dataset: https://www.arcgis.com/home/item.html?id=4533407decd94428817a228cb36964cf Jay Sandhu

To make sure your evaluator is working properly, you can do the following two things: Add the network dataset to ArcMap, zoom to where you are doing your route and then on the Network Analyst tool bar, click on the network identify icon (second from right). Now click on any edge and it will pop up the network attributes of that edge and what it is connected to. Check to make sure the OneWay is prohibited as you expect it to be. The other thing you can do after you add the network dataset to map, bring up its properties and then on the symbology tab, turn on Edges and then click on the edges to bring up the symbol to use and click on arrows and turn on draw arrows on edges and check on one way, click ok. Now the network dataset will symbolize with the one way direction highlighted with arrows. Does it match what you expect? You can also check what values are stored in the OneWay field that the evaluator is using. Are they N, TF or T?

Mele, You can start by looking at the help here: http://server.arcgis.com/en/server/latest/publish-services/windows/gp-service-example-network-analyst-overview.htm Then look at this example for Service Areas: Geoprocessing service example: Drive-time polygons—Documentation | ArcGIS Enterprise You can use the above example and replace the Generate Service Areas Tool with the Solve Vehicle Routing Problem tool in the GP model to publish the VRP service. The Solve VRP tool does not support field mappings. You have to make sure the inputs match the schema of the depots parameters. Meaning, do the required field mappings as some sort of pre-processing in the GP model. Once the GP service is published, it can be used with the geoprocessing widget from the Web App Builder to create a custom app. Regards, Jay Sandhu

If you just want to know what is at a point, you can simply use "select" all the lines at that point and summarize an attribute field. If you want to know what is under another arbitrary line (highway corridor), you can run CLIP against it and it will write out the portions of features that cross that corridor (line) and then you can summarize the attribute. More info on these tools here: An overview of the Extract toolset—Help | ArcGIS Desktop An overview of the Statistics toolset—Help | ArcGIS Desktop Jay Sandhu

If you are looking for physical connectivity issues (not the ones caused by attributes like oneway's), you can use the Utility Network tools to find disconnected parts from some known location. Take a look at: Find Disconnected Features in Geometric Network—Help | ArcGIS Desktop Note that this will require you to create/build a geometric network. Once you correct your issues, you can delete that and create a network dataset for use with Network Analyst. Alternatively you can use the Service Area solver (with the lines option) to find things that are "connected". Once you have this as a selection, invert the selection to find features that are not connected. Jay Sandhu
