OSM relies on the contributions of many people, most of them are not going to spend much time learn stuff - particular complicated stuff that they don't see in their day to day life. The complexity of things like the values of 'opening hours' mean it does not get used by many. OSM should try

Exactly. From a routing point of view, if you encounter a residential road, little can be deducted with certaointy from that tag. E.g. live very near a residential road, where along the length are lots of houses, but these are shielded by ridges, bushes and separate cycleways so traffic is not imp

It's a bit of a mess in Nederland as well - lots of small residential roads have once been imported as unclassified, under the assumption that unclassified means there is no official classification. Which was wrong because unclassified is in fact a classification. As a result, unclassified in OSM i

Re: [Tagging] Clarification unclassified vs residential

That is a most interesting question. Here in Thailand I interpret their differences, perhaps incorrectly, as residential meaning a way with houses on it, while an unclassified highway is one step below a tertiary and therefore one step above a residential. It does not have many houses (residences)

[Tagging] Clarification unclassified vs residential

Hi, i found some changesets downgrading streets to unclassified. After some discussions the mapper were under the impression that unclassified is something higher priority than residential. From my long tagging practice in OSM unclassified and residential are identical in respect to priority. (An
