Joseph, There are geometry related errors in the street data that makes up the network. For starters, the input lines have XYZM where the Z's ad M's are zero. The M's do not play any role in locating features for network analysis, but Z's do have an impact. Also there is no vertical coordinate system defined. At a minimum bring up the properties of the RdsClean feature dataset class and for the Z Coordinate, assign a Unknown height system in meters. But the main problem is that you have many line features that have 0 length and some that are 0 but have a length! So if you examine your data in the area where the points are getting loaded, and look at TofinoRdsCleanND street feature id of 195, it shows a length of 13 meters but is in fact length 0. This feature is close to the points that are not getting located. You could delete this feature and rebuilt your network. Now your points will get located. There might be other places where there are problems. You really need to clean up your street data for any meaningful network analysis Jay Sandhu

Best course of action is what Melinda had suggested. Please contact Esri Tech support and share your data/project and we can help diagnose what is going on. Regards, Jay Sandhu

Can you solve the same route in Pro without using the Find Best? Does that also fail or give some error/warning messages? Jay Sandhu

The returned error message tells you exactly the problem you are having in this case. No valid stops. It is likely that either the WashingtonSt_Start_1 has less than 2 point features OR a selection that has selected only 1 point feature. In which case the route solver cannot solve the route with less than 2 stops. Jay Sandhu

Can you reach these locations using a regular route instead of VRP? I am wondering if there are network issues (oneway, etc.) that may cause no paths to be found. You can also use the Network Identify tool on the NA toolbar to examine the connectivity of the edges in that area. Jay Sandhu

If you have a one-way street, then you can only travel along one direction. So stops can be located on either side of the a one way but they will have to be visited while traveling along the the same way as allowed by the one-way setting. What would be your ideal solution? Visit the stops on one side first and then go around the block and visit the one's on the other side? Perhaps that can be managed by loading the stops in two steps. First load all the orders on one side and then load the other side. That way they will not be mixed together to do the zig-zag. Jay Sandhu

Couple of things to check: Do you have multi-part line features in your inpit data? In that case, you can have streets that have gaps! You may want to use the GP tool, multipart to singlepart to get around that. Also, how are you loading your stops? Are you using location fields by any chance? If yes, re-locate them or load them again using geometry. When you re-build a network, the location fields can become stale. Jay Sandhu

This problem may happen when the internal network topology is stale and the route is traversing an element id that no longer exists, thus it stitches together a straight line for the road it cannot find. Make sure the network has been built and the route re-solved on the built network. Jay

Elevations are not necessary to create a network dataset. The most basic way to create a network dataset in Catalog is to right-click on the lines shapefile and choose New Network Dataset. Then Next through the wizard taking all defaults and then click Finish. That should create a network dataset. Can you also check if there is an existing network dataset based on the same lines shapefile in that folder? A shapefile can only participate in one network dataset at a time. Jay Sandhu

Just to rule out the issue of a dropbox, can you copy the shapefile to a new folder on your local disk drive and try again? Also, what version of the software are you using? Jay Sandhu

Do you have write permission to the folder where you are creating the network dataset? Jay Sandhu

Different Network datasets (SDC over the years) can produce different results as new roads are built or existing may change (re-align, or become one-way, or new turn restrictions have come in, etc.). Also if you are using a Start time to solve the closest facility then solving on a different day/time can change the results. In your case, for the 11 that are different, you can solve for two closest and see if the second is what you were getting before and what is the difference between them. In general, if you have solved a closest facility once and there are no changes to the data or analysis settings then you will get the same answer if you solve it again on another day. Jay Sandhu

If I understand your requirements correctly, you should be able to take your existing line feature that represents the bus route and create a network dataset on it. That is, turn it into a network. Then use the Route solver to solve a route between the stops in order of visiting them. Then thing you will need is some cost attribute on the line feature that tells how much travel time it takes to travel along that line. Jay Sandhu

If you use Minimize Impedance then this should not happen. One more thing to check is the network locations. When you loaded the demand and facilities, did you use network locations? They can get stale, especially if you are editing/building the network. You could make a new Location-Allocation layer and load in the demand/facilities using geometry and not network locations.If it is still happening then I suggest that you get in touch with Esri tech support and have them look at your data and settings.

What model are you running with Location-Allocation? The Maximize Capacitated Coverage can allocate demand points to further away sites if there is no capacity in nearby chosen facilities. The other reason a point may appear to be allocated to some facility further away is due to the transportation network. For example, if you run a route from one of those 11 sites to a "closer" facility, do you get a shorter distance? The network may not have a path to the nearby facility. Jay Sandhu
