Implement drive-through check (attempt 2)

Open Famlam opened this issue 1 year ago • 0 comments

New attempt based on feedback in #1521 (new PR as it's mostly a rewrite; keeps things clean :) ) Fixes #1499 - Check for potential driveway/drive-through mix-ups.

  1. Start from highway=service + service=drive-through (and not a oneway, which is just a shortcut as oneways are theoretically never dead-ended)
  2. Get the end nodes of this way
  3. Filter out (via LEFT JOIN + WHERE ... IS NULL) the end nodes that are connected to any other way
  4. Filter out (the last JOIN) i.e. turning circles (which could make it a valid dead-end drivethrough) and entrances (if e.g. the indoor part isn't mapped)

Results of some countries attached; no false positives so far; several "bad" drive-throughs found. (Note: in my local tests I disabled the class=1&2&3 analysers, hence their results are not listed)
