Bug? Centrality not respecting restriction attribute

[Patrick McGrath]

Centrality is not acknowledging restricted edges in my network dataset. The labels in the image below show the Reach values for my input points, and points located on restricted edges have positive Reach values when no travel should be possible from them (Reach should equal zero). Standard Network Analyst tools such as Make Route Layer acknowledge the restrictions and solve accordingly (see green line in image below). I tried several earlier versions of the tool and had the same problem. I have the same problem with Straightness.

 

I wonder if this is related to how MakeODCostMatrixLayer is called within Adjacency_List_Computation.py (line 170). I see that no restriction attribute is passed to it. I tried hard coding in my restriction attribute and the tool failed at step 4 (see 'MY CODE SNIPPET" and "ERROR" below), but it did seem to be acknowledging that some of the points were on restricted edges ("99 out of 1364 input points not recorded in graph"), which did not happen with the unaltered code.

 

As always thank you for your hard work,

Patrick
