You can use the Location-Allocation solver. Make the  park entrances as facilities and the friend locations as demand. Solve for 1. It will find the location of the park that minimizes overall travel time from all the friend's. However the solution may not be equitable to everyone as some may have to travel more than others. You can put in a travel time cutoff and try to find another solution. This solver has many options, so you can see what gives you a good solution.

Generally speaking, if you use OSM data, you should set Any Vertex connectivity and build the network. You do not Integrate as that WILL create end points/vertices where streets cross. Also you do not need to remove the motor ways and links. Just have a restriction that turns them off in the network dataset for pedestrian routing. Jay Sandhu ... View more

The important thing to model is the connections, turning restrictions and having accurate travel times. You do not need to digitize the curves as long as the road centerlines capture the connections accurately. You can add in turn restrictions at places where turns are not allowed.  Jay Sandhu ...

Well assuming that the change from 50 to 25 will make it twice as slow, AND entire line features are affected, you can set the scale cost factor to be 2.0 You can select the affected line features and then load them as barriers. If the slow down happens to start and/or end in the middle of a road then you will have to create an appropriate line feature. The slow down should still be 2.0 If this is a permanent change then you should consider updating the values in the network dataset and rebuilding it. Jay Sandhu  ... View more

The concept of barriers in a network analysis layers is designed for this scenario. You can have point, line or polygon barriers. The barriers can be a restriction or a scaled cost. So you can have a polygon of an area where a weather event is slowing down traffic by 20%. You can load that into your route analysis layer with the a scale cost of 1.2 More info: Barriers—ArcGIS Pro | Documentation Jay Sandhu ... View more

The arcpy.nax api uses different field names that when using a layer so “Cutoff_Minutes” is not automatically used. In your scenario you can rename the input field or use a field map. Using the field map will look like:   # Map fields fieldMap_demandPoints = loc_alloc.fieldMappings(arcpy.nax.LocationAllocationInputDataType.DemandPoints) fieldMap_demandPoints["Cutoff"].mappedFieldName = "Cutoff_Minutes"   # Set the default value to use if the field value is null (optional) fieldMap_demandPoints["Cutoff"].defaultValue = 15   # Load inputs loc_alloc.load(arcpy.nax.LocationAllocationInputDataType.DemandPoints, input_demand_points, fieldMap_demandPoints)   You can always get the field names list if you don’t know what to map or which names will be used automatically:   print(loc_alloc.fieldNames(arcpy.nax.LocationAllocationInputDataType.DemandPoints))   ...

Do you get this message if you do not leave the default value null? Even if there is a default value present, the field values on the demand points take precedence. So it should be ok to set a default value if that works.  Jay Sandhu ... View more
