Can I enter a "distance tolerance" when routing in Network Analyst/Navigator

In Network Analyst, and in ESRI Navigator, I want to be able to specify a maximum distance that route will navigate to. So that if a route wont get me to within, say, 20 metres of my destination, using a particular travel mode, it will report this.

Currently it is stopping 1.5km short, stopping on the motorway, because the current travel mode (red/black) wont allow it to get any closer.

I need it to report an error here back to the user, not just end the route where it is.

I would have expected to be able to enter a "tolerance" value here somewhere that limited the "walking" distance at the end of the route to say 20 metres.

Apologies, in advance if this is a no-brainer question, I am very new to the world of ArcGIS

Hi,

I'm not sure if there's a built-in way to do it, but you could generate a buffer from your destination and check to see if your suggested route intersects it.  You could also generate a Service Area for the walking distance and see if it intersects that.

Thanks David - I'll give the service area idea a go, I'm not sure the buffer approach will work for us, as we need to roll it out to clients' vehicles through ESRI Navigator. Will let you know how it goes.

When you add the stops locations to a route, the stops feature class has information on how they are from the street feature they are snapped to. You can limit the distance a stop searches out for the nearest routeable street in tools like Add Locations. Here is screen shot from a route in ArcGIS Pro and the related field values in the Stops attribute table.

Wonderful Jay - this is is exactly what I was looking for. Do you know if it is possible to do a similar thing in ESRI Navigator on the mobile device? as that is what the end user will be doint.
