Network Analyst does not use polygons as inputs as it can only route on street segments. So you have to represent the polygon by one or more points. Are there roads inside the forested areas/polygons? You can generate points on these roads instead of having just one centroid to represent the polygon. You can also use the polygon to intersect the roads and see where there are points on the border to help with the distance calculation. Jay Sandhu

Perhaps the best way to start is to run through the tutorial for creating network dataset here: Create a network dataset—ArcGIS Pro | Documentation Say you have a field called segment_score You will need to add a cost attribute called something like segment_cost and then set it to a field script of type python with the result value being !segment_score! Hope that helps. Jay Sandhu

Just an FYI, Mike Price has written numerous articles about fire station response. You can read some of them here: Mike Price, Author at Esri and Mapping Current and Proposed Effective Fire Response (esri.com) Measuring Firefighter Performance with ArcGIS Pro (esri.com) Regards, Jay Sandhu

The display only shows a limited amount. You can increase the width of the field display in the UI. But how do you plan to use this information? For example, you can use the GP tool Export table and output to a text file. You can also choose to only export that one field you want like so: Jay

Are you looking to create an Origin Destination cost matrix of air miles or highway drive miles between the airports? Just having a location of airports and connecting them with straight lines does not mean that there is any actual air service between the airports. Regards, Jay Sandhu

Basically yes. But I would still look at each restriction and understand what you are turning off as you do so. Regards, Jay

Yes. It is possible. Here is one way: Use the Summary Statistics GP tool. The input should be the routes feature class from your Closest Facility layer. Open the route table, and sort ascending on the Facility Rank Column. Then right-click the Facility ID column and bring up the Summary Statistics. Choose the FacilityID as the statistics field and pick Concatenate from the list of statistics type drop down. Then type in a comma in the concatenate separator and run the tool. It will output a new table with a field that has all the FacilityID's separated by comma. See screen shot below. Jay Sandhu

It depends on what kind of restrictions are present in your network dataset. There may be some you could turn off and some you may want to leave on. For example, you could turn off one-way's and turn restrictions off but you have no way of knowing how fast you can travel the wrong way on a one-way restricted road. You may not want to turn off bike lanes or dirt roads as the police vehicle may not be able to use those lanes. So in general you should route with the correct travel mode and perhaps turn off some restrictions such as turns. You can also as the local police drivers what restrictions they are willing to ignore to get somewhere fast. Jay Sandhu

Have you checked if you have a read only file share? Or you can try to copy it to another location and see if that works? Jay Sandhu

The script looks ok. I would suggest that you go ahead and use it, build the network and then add it to Pro and use the Explore tool to check the network cost/restriction values and make sure they are what you need them to be. More details on Explore Network here: Explore Network—ArcGIS Pro | Documentation Jay

Lorenzo, The python scripts for the cost/restriction evaluators had problems and that is why the time values being computed for the edges were not right. My colleague @MelindaMorang fixed the data and rebuild the network and now the route TSP sequence is better. I am attaching the updated network here. Jay Sandhu

What network dataset are you using to solve the route? I tried using ArcGIS Pro 3.1 and a version of Europe data from Here from this year and I get different sequance with your stops. I got an even better result when I use the AGOL route solve which is based on Pro 3.3 and latest data. Attaching a screen shot from my Pro 3.1 solve. Jay Sandhu

It is hard to tell what could be going on without looking at all the point data. If you can share the data we can evaluate. You can zip and attach the stops file here. Jay Sandhu

There are couple of different ways to solve this. Do you need three routes, to each of the school from the same starting location (police car location)? So, you can use the route solve, three different times OR you can use the Closest Facility Solver. Load the police car shape file as the facility. Load the three school locations from the second shape file as incidents. Set the travel direction to travel from Facility to Incident and solve. This will give you three separate routes. See screenshot below. Jay Sandhu
