I started working with pgr_drivingDistance. Lot of edges (marked as yellow) are missing from result.
Those seem to be cases, where routing algorithm has approached to same edge from two directions.
Is such result normal and expected?
I can fix those missing edges with separate queries, but at first I would like to be sure, that I haven't messed something up myself.
EDIT: I have added some post processing now to fix those missing edges.
I have used different software versions (Win platform): latest versions (Postgres 11 + PostGIS 2.5 + pgRouting 2.6) and Postgres 9.6 + PostGIS 2.4 + pgRouting 2.3. Results are identical.
