So looks like you have some routing service (that utilize your network dataset) that you would like to expose to your constituents.  The way it is supported is to publish your routing services on your own server (using publishing routing services utility). You can then use a geoprocessing widget with web app builder in AGOL to create a web app that exposes your service to your constituents. More on the publishing utility and web app builder here: Publish Routing Services utility—ArcGIS Server Administration (Linux) | ArcGIS Enterprise  Web AppBuilder for ArcGIS | ArcGIS  Jay Sandhu ...

What is your use case for publishing a network dataset to AGOL? Thanks, Jay Sandhu ... View more

Origin-Destination solver gives network distances, NOT straight line distances. It's goal is to return the shortest path distances quickly and so does not bother computing and returning back the shape of the actual shortest path taken. If you do not need the resulting path shape then use Origin-Destination solver. IF you need the route shape geometry then use the Closest Facility solver. It is similar to OD but takes longer to run as it will return back the route shape geometry. Network analysis solvers work on shortest paths on the network, not euclidean. Jay Sandhu ... View more

Network Analysis allows you to load locations from point features. You do not have to click on the map to set your start and end locations. See the Add Locations tool. In your case, you will need to convert the polygon to one point (centroid) or come up with a method to convert the polygon into a meaningful point(s). For example this could be all the points on the street that the polygon intersects with. Also, do you need to find distance from each polygon to the same one point? In that case you could use the Origin-Destination solver (if you do not need the shortest path shape) or Closest Facility solver instead of the route solver. Jay Sandhu ... View more

Yes, VRP fleet needs to be homogeneous. So if you know ahead of time that some vehicles cannot be used on a certain date due to odd/even license plate restrictions that then do not load them (as routes) into a VRP layer for that day. Jay Sandhu ... View more

You can do this in a couple of way. One is to simply add restrictions for odd and even days and then pick the appropriate restriction to use based on the license plate. The other way is to use parameterized restrictions where you set the parameter at run time based on the license plate and the restriction is triggered as appropriate for each network edge. This is useful when dealing with bridge heights and tall vehicles. You can read more about it here: Using parameters with network attributes—Help | ArcGIS Desktop  Jay Sandhu ... View more

Make sure that the restriction DrivingAVehicle is turned off when you are using PedestrianTime impedance. Jay Sandhu ... View more

There are some restrictions that are on by default. You will have to make sure on the OD analysis layer properties that all restrictions are turned off.  If you still cannot find some paths then contact Esri tech support to have them get the data in house and determine the reason why paths are not being found.

Perhaps there are some restrictions in the network (like a gated community) or disconnects that prevent finding paths. Do a solve where no restrictions are on. Does that give more paths? If hierarchy is on, try turning that off. If still no paths, then there might be disconnects in the network. What network dataset are you using? If you open up the attributes of the origins or destination feature classes and look at the Status field, it should normally say OK. But for locations that were moved to due to restricted edges it will say Not on closest. Are these the locations that are not giving paths? OR the one's that have status OK that are not working. I think you will have to isolate some locations that do not work to figure out why paths are not being found.  Jay Sandhu ... View more

How did you load in the locations after changing the exclude restricted settings? Were you loading by "network locations"? Those could be the old pre-computed locations that fell on restricted edges. You need to load by geometry. Jay Sandhu ... View more

You will get that message if the locations (origins/destinations/facilities) are located on edges that restricted. In that case there is no path that can either start or end there. One way to get around this is to locate on another close by edge rather than the closest restricted one. The way to do this is either bring up the OD or CF analysis layer properties, then on the Network Locations tab at the bottom, check on the option to "Exclude restricted portions of the network", and then load in the locations. The other way is to use the Add Locations GP tool to load the locations and then check on the same "Exclude restricted portions of the network".

>Set the stop source as streets could avoid a U-Turn certainly, however is there any solution in network analysis to avoid U-Turn when the stop is set at the junction? As I explained in the previous e-mail, this is not possible. >Image that there are lots of waypoints set in the junction, the vehicle will go through these crossroads. And we also not allowed U-Turns. How can we implement it in ArcMap? Why do the waypoints need to be on junctions? One way to implement this: Let's say you want to get a route from A to B to C and want to avoid a u-turn at B (to C). Solve a route from A to B. Then use the Copy Traversed Source Features tool to get a list of edges that make up that route. Get the last edge ID (or create a point from it). Now do a route from B to C but put a barrier on that last edge. Combine the results. And do note that you may not get a path from B to C if u-turn was the only option. Jay Sandhu ... View more

When a stop is located on a junction than the curb approach property does not make sense as you can not figure out which way is the left or right side of that location. This is documented here: U-turn policies—Help | ArcGIS Desktop  You can see the caution note in the curb approach section: And this also explains that the U-turn at junction property applies to junction that occur in between stops. So a way to not get into this issue is to locate your stops only on edges and not on system or override junctions of a network dataset. You can control what network sources to locate on from the route analysis layer's properties or on the add locations tool. Jay Sandhu ... View more

If the network identify is not able to reveal any obvious problems like overlapping edges, etc., then contact Esri tech support and have them get the data in house to see what could be going on. Regards, Jay Sandhu ... View more

You should be able to add the u-turn restriction in the blue arrows. Is the network built? Can you use the network identify and inspect the edges and connectivity in that area to see if that will give a clue. To use the network identify, add a network dataset to ArcMap and then on the NA toolbar, use the second from the right icon. Now you can click on an edge/junction and see the connectivity information. Jay Sandhu ... View more
