Hallo Damien

About a “turning_radius” tag:

- How should a mapper collect this data? I have absolutely no clue what value I should use for a given curve or crossing.

- If you have any kind of crossing ways, you need turning_radius for every pair of roads. This looks like turn_restriction relations.

Here another idea:

- Use the existing geometry (angel between two way segments connected at a point) and width (use a default for normal tracks)

- Do some math and geometry to calculate, if a truck of a given width can pass this way.

- Perhaps you have to look on more than one node (more than two way segments) if the way nodes are very close.

Best regards

Michael

Betreff: [talk-ch] turning_radius

Hello,

I do a bachelor in forestery in a high school (HAFL Zollikofen). For my bachelor thesis, I would like develop a navigation system for the trucks in the forest (wood transport) with OpenStreetMap.
But for the mapping, one tag is noexistent. I need to indicate the turning radius, it's very important to now when we can go in the bends with the trucks.

What do you think about "turning_radius=** (in meter)" ?


Thanks you and best regards,

Damien Jordan
