[Tagging] Differences in cycleways

[Robert Elsenaar]

In my study of the evolution of mapping cycleways in OSM I found out there 
was a moment cyclistshad a problem to render lanes and tracks and had the 
strong wish to create usefull cyclemaps. They did decide to avoid the render 
problem en start mapping for the renderer. apperently they made the 
descition to map all cycle pathes that are a little bit saperated  from the 
car lane directly as highway=cycleway.
The advantages you mentioned by using seperated cycleway is just because a 
leak in tagging possibilities.

Example:
========
Way 1:
highway=secundary
name=Duinweg
surface=asphalt
maxspeed=50

Way 2:
highway=cycleway
surfase=paving_stones
maxspeed=30

Solution:
============
highway=secundary
name=Duinweg
surface=asphalt
maxspeed=50
cycleway=track
cycleway:surface=paving_stones
cycleway:maxspeed=30

This kind of solution will make:
- mapping easier,
- tagging stays the same
- No missing intersections
- Routing keeps possible
- cyclewaytrack got at last a proper name
- Streetrelations becomes easier.

Wil it make a change in a approval process to develop a proposal on e.g. 
..:surface=* ..:maxspeed=* etc,etc ?

Personally I consider cycleway=track a preliminary state before a
proper highway=cycleway is drawn. It is intended for cycleways that
are parallel to a street. There are problems with either approach:

- either you draw a separate way (highway=cycleway), with the benefit
of being able to set proper maxspeed, surface, oneway, lanes, access,
turn-restrictions and other tags for the cycleway, but risking that
not all possible interchanges are mapped initially (common mapping
mistake). This also allows for small geometric details that otherwise
get lost (positional accuracy). The backdrop is that in some cases the
cycleway gets lost below the street in the rendering (dependent on
render order and render widths).

- if you set a cycleway=track you will not have most of the details
described above, but you'll have less work and possibly it will look
nicer in the rendering (if you don't care for details).


cheers,
Martin
