What settings were used in ArcMap and Pro? Default? Do note that by default, ArcGIS Pro does Standard Precision and not Generalized. In ArcMap, the default setting is Generalized. ... View more

Do you want to define a directed graph based on the sensor locations OR do you want to find shortest path network distances between them? The second can be done by using the Origin Destination Cost Matrix service on AGOL which uses a pre-configured street network datataset. https://developers.arcgis.com/features/directions/#travel-cost Jay ...

Polygon barriers will "slow" down the entire route as they impact all the edges inside the polygon. And if you are applying it to the entire country, there maybe too many edges and performance will not be good. Also, barriers "scale" the cost on the features, not add a fixed cost. The correct way to model a border delay or cost is to identify the border crossing edge and change its cost OR add a Turn feature there with the additional cost or place a junction there with a cost to go through the junction. Just note that junction costs are same regardless which way you cross them, whereas the edge costs can be bi-directional. Jay Sandhu ... View more

Looks like you have a connectivity issue with your new network dataset. You can use the network identify tool to see if that is the problem. This tool is on the network analyst toolbar towards second from the right. Add the network dataset to map and then use the tool to click on any edge. Is it connected to any other edge? Are the cost values ok? Perhaps that will tell you what the problem may be. Jay Sandhu ... View more

Network Analyst supports loading in "barriers". These barriers can be absolute or relative (scaled cost). So if your hazard areas are polygons, then load then as scaled cost barriers with a high scale cost like 10. Now find a route between your start/end locations and it will avoid these areas unless there is no other way to get to the destinations. http://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/barriers.htm or  https://pro.arcgis.com/en/pro-app/help/analysis/networks/barriers.htm Jay Sandhu ...

Since you are interested in 25 minutes of a polygon boundary, you will need to convert that into "points" as network analysis works on point locations on a road network. So use the GP tool Feature To Line to convert the polygon to a line feature class. Then use the GP tool Intersect and overlay the polygon line with the street lines making sure the output type is Points. This will create points at all locations the polygon intersects the streets. Now you can use the Origin Destination Cost Matrix solver and load these intersection points as Origins and your super market points as Destinations. Set the Cutoff to 25 minutes and solve. It will find all the super market points within 25 minutes.  Jay Sandhu ... View more

>Why do you think that it is not suitable for routing?  This data does not contain any information on transportation related attribute such as drive times, speed limits, one-way information, turn restrictions, how the ramps connect (z-levels), etc. If you create topology and flatten out these intersections then you will get wrong paths. There are many other things needed to make a meaningful road network. You also mention: >I was studying on Road network files   If you see the information on that web page, it says:  "these files are not suitable for engineering applications, emergency dispatching services, surveying or legal applications" So it depends on what is your use case for the routes you are creating. As far as ArcGIS online, you could create a new trail account and try out these ready to use services. It comes with some limited amount of credits.

I believe this data is for "display". It is not really suitable for routing. If you have an AGOL account and credits, you can use the online closest facility service and get routes with current street network. You can access this from the Ready To Use services in ArcCatalog.

What is the source of the original data for "North America Major Highway"?  ... View more

It looks like the original data has some corruption. Are you running the topology, intergrate, etc., on the original or the resulting route layer? You may want to contact Esri tech support and have them get the data in house and take a look at it. Jay Sandhu ... View more

Have you tried changing (not specifying) the XY tolerance? Are you able to do some other geometry operations on the output routes. That is, try exporting the routes to a line feature class or buffer them. Jay Sandhu ... View more

You can have an attribute on each shape that defines what kind of shape it is. Then you can add restrictions based on the different types. At solve time you can choose which restrictions you want to use to solve on. You can also encapsulate the different types of impedance attributes and restriction attributes into a travel mode. You can take a look at the tutorial data, especially the Paris multi-modal network dataset on how the restrictions and travel modes are set up. You can get the data here: http://www.arcgis.com/home/item.html?id=d6bd91b2fddc483b8ccbc66942db84cb  and travel modes: Travel modes—ArcGIS Pro | ArcGIS Desktop  Jay Sandhu ... View more

> Every time I digitize this one segment, build the network with no errors, and run the OD Cost matrix tool, it wipes out that One Pad completely from my "Trucking Time" results.  Some things to try: If you are using ArcMap, can you use the network identify tool and make sure that the new segments are connected to the existing streets? Can you run a simple route solve using the new segment? Or you can run a service area (with lines option) from a location on the new edge to see if there is connectivity. The network locations that you are passing into the OD tool, do they have existing/pre-computed network locations that are being used (they may be stale). Jay Sandhu ... View more

I can't say why the sub layer drop down list would be empty. I would suggest trying to recreate another model and seeing if the problem goes away. Jay Sandhu ... View more

When a location if snapped along and edge (not at end points), then only a part of the edge becomes part of the solved route (depending which way the route goes). When the shortest path time and/or distance is computed, only that part of the traversed edge counts. The travel time or distance is pro-rated. If you have solving on a local network dataset (not online), you can run the Copy Traversed Source Features tool to write out the individual segments that makes up the whole route. You will see that the first and last edge are using not whole edge features but an actual percentage is written. The locations can snap anywhere (percentage) along the edge not just at the closest vertex. Jay Sandhu ... View more
