Faud, Since the values are working when you use the create network location tools, then most likely when you use Load Locations, some setting is not being set so that the attr_traveltime values are not being loaded into the barriers. See my screen shot. Make sure on the Load Locations, the Barrier type is set to Added Cost and that the Attr_TravelTime property is mapped to the field Attr_TravelTime. After the load, open the attribute table for the barriers and make sure the right values are loaded. Then also make sure that you are solving the CF layer using the TravelTime attribute and that the values you loaded are meaningful. For example, if the units are minutes for TravelTime, the delay from the point barrier layer is also in minutes.  Jay Sandhu ... View more

In ArcGIS Pro, the VRP solver is supported via the SolveVehicleRoutingProblem GP tool. It can take in a route zones polygon as input on that tool. See the doc (search for route_zones on the web page) for more info: Solve Vehicle Routing Problem—ArcGIS Pro | ArcGIS Desktop  Jay Sandhu ... View more

Your main criteria listed is "distance" as in distance to main roads, etc. So that is the attribute you need in your network dataset. The rest can depend on the types of vehicles you need to use and road restrictions to support that set of vehicles. "Optimal location" is a methodology and Location-Allocation can be one part of that methodology. You need to come up with candidate locations that satisfy your "distance" criteria and locations that are available to support a tea processing plant(s). And then you need the locations from where the tea is coming from, i.e., demand locations. The actual Location-Allocation process only minimizes weighted-distance between the demand and chosen facilities to give you the optimal location. So you may need to evaluate the results in terms of your overall goals and run location-allocation with different scenarios to find a set of locations that satisfy your goal. If you do not have a network dataset, then you could use the online services on arcgis.com to do Location-Allocation or use the ready to use services within ArcMap or ArcGIS Pro. Jay Sandhu ...

You can get information on the routing data that is used for the ArcGIS Online services here: Travel modes—ArcGIS Online Help | ArcGIS  Routing with StreetMap Premium in ArcGIS Pro—ArcGIS Pro | ArcGIS Desktop  Also note that most commercial data do not include information on which intersections have traffic lights or stop signs.  Jay Sandhu ...

Network Analyst is meant to solve shortest paths (routes) based on a network dataset. The "routes" you are doing fall under the domain of  linear referencing. The route, measure terminology from linear referencing does not mean the same as finding a shortest path route. So in case you do want to publish a network analyst routing service then you need to have a network dataset (that contains the topology and costs associated with each edge, with appropriate restrictions such as oneway, turns, etc), and then use the make route layer tools, etc.  If that is not your intent, then if you have a model that does exactly what you want (using linear referencing tools), you should be able to publish it without involving network analyst.

Are you able to add the shape file to ArcMap and draw it and open its attributes? Most likely there is something wrong with the shapefile data so that the network dataset functions are not working on it. Jay Sandhu ... View more

Chris, This is very old information: The Arcview format for the a turn table (.dbf) at a minimum needs three columns called Node_, F_Edge and T_Edge. Similarly the workstation ArcInfo turn table (.info) format had Node#, FromArc#, ToArc#. You can rename the columns CENTRELINE to F_Edge and CENTRELI_1 to T_Edge (or you can add new fields and copy values to them). But I am not sure where you will get valid Node id's that were part of the AV network analyst shape file (Nodes.dbf) for the GP tool to disambiguate the  from/to edge ids and come up with a valid turn. There is an INTERSECTI column in the turn table and perhaps that can be put to some use. For example, you can try to make a network on your shape file centerlines. This will create a junction's feature class with junction ids. You can then try to match the junction id's to the INTERSECTI field (maybe a spatial join may work). I would suggest doing this for turns at one intersection and see if you can make it work. Jay Sandhu ... View more

Chris, I understand that the format of the file is a shape file. But that in itself is not enough to make it "routeable". Do you have the street centerlines on which you will be doing the routing? The enclosed centerline_flow shape file in that location is not a connected street network and cannot be used for routing.   Drawing the contents of the turn shape file in ArcMap, it seems to draw all turns at an intersection and the turns are offset from the centerlines. ArcView 3x, workstation ArcInfo or the newer ArcGIS does not represent turns in this format. Looking at the attributes of the turn_restrictions_mtm3 shape file, it has a column called MI_PRINX. That indicates to me that it perhaps originated from a MapInfo system. You will have to understand how it represented the turn information. For example, there are a lot of turns with the TURN_IMPED set to -1. Does it mean that turn is not allowed? In which case almost all movement would be restricted. Or does it mean that the turn does not impact routing? So it is possible that you could do some transformations on the input data to make it amenable to our turn table conversion tool, you will still need a useful centerline file for the actual routing.

Generally there are no limits to how many stops that can be loaded into a route layer and then solved in the order you load them. But there are going to be practical limits IF you are trying to optimize or find best way to visit them with the Reorder Stops To Find Optimal Route option. Generally you want to cluster/divide points into manageable sets and then find the best way to visit them. For that, I would suggest using the Vehicle Routing Problem Solver instead of the Route solver for delivery routes. You can specify vehicle and capacities, etc. But I want to caution you that if you are trying to optimize residential trash pick up, then the best way to solve that kind of problem is with a different type of solver (Chinese postman problem or arc routing). We do not have a solution for that. The VRP can be a substitute but may not be best for your needs. Jay Sandhu ... View more

Chris, The documentation for the Turn Table To Turn Feature class tool states that:  Converts an ArcView turn table or ArcInfo Workstation coverage turn table to an ArcGIS turn feature class The file you have, turn_restrictions_mtm3, does not appear to be a valid ArcInfo or ArcView turn table. That is why the tool is not accepting that table. What system did that file come from? Perhaps it was converted into a shape file format from some other system and not really started as files used for network analysis in ArcView. Jay Sandhu ... View more

Take a look at the GP tool Copy traversed Source Features. You run this after you solve the VRP and it will write out all the edges that were traversed by all the routes. You can select only the ones that have orders on them. You can do this either by spatial select or perhaps using the FromPosition and ToPosition are not 0 or 1 (unless the order snapped to an end point). Once you have that edge, you can get the distance from a field like Attr_Meters. Jay Sandhu ... View more

There are also FromPrevTravelTime and FromPrevDistance columns on the orders table besides the Cumulative ones. Jay Sandhu ... View more

"actual order distance" Do you mean the distance between one order to the next? If yes, it is available in the Orders attribute table of the VRP analysis group layer. Jay Sandhu ... View more

Glad you figured it out! As I had mentioned before, you can have many costs in the network dataset. But for each routing analysis you have to pick the one you want to use. In your case, the global turns were associated with one of the costs. If you do not pick that cost to solve on then obviously the turn delays were not getting used. Regarding the suggestion of current .vs. default. I think default is appropriate. It is a setting in the network dataset that acts as a hint to the route analysis layer to use it. But you can change the cost in the route analysis layer. That does not change any settings in the network dataset, i.e., the new cost picked for routing does not change the default settings in the network dataset. Regards, Jay Sandhu ... View more
