How to detect a wrong/improper/broken highway classification/hierarchy?
Skrevet af naoliv den 3 september 2014 på EnglishSometimes I see highways with a broken classification/hierarchy on the map.
For example:
- in green we have a small
tertiary
section connected toresidential
highways; or this smalltertiary
should beresidential
like everything else or we are missing sometertiary
highways on the area - in red we see a
residential
section that should be, at least,tertiary
(connecting thesecondary
to thetertiary
highway)
Another example:
- in green we see some
residential
sections that should besecondary
, making it a continuoussecondary
highway - in red we see an isolated
primary
section (which probably should also besecondary
)
Do we have any tools to detect (or help detecting) cases like this, where the classification/hierarchy is broken?

Excellent question. Seems like a SQL query would be able to catch this. I just don’t happen to have resources for it personally.

In fact Osmose QA already check for this.

Hello “Brazil” contributors”…
I think your community must work for to make a spacial tools for that (I don’t know if it’s a case?…). In my country, “FRANCE” we have a special tool, however, it’s not perfect (like everybody…). You can see this tool at this link below:
http://tile.openstreetmap.fr
And select IGN Route500.
This is an example for my country “only”, probably the same thing exist in other countries. Ask this question to your community and “friends” or seek in the Wiki…

Use http://peirce.gis-lab.info/qa/WORLD Search for “Brazil” and click on a name Then look for “Изолированные рутинговые подграфы” and subitems. To see them on a map, click “на карте”. Example. Clicking on a marker opens JOSM at that point.
The validator was written by Zkir and is updated around once a month.
