Route statistics

[karussell]

More insights into routes, especially bike routes is very valuable.

Especially when tuning them. And so I always wanted to create some statistic overview per route. And as this is not only useful for developers but also for users I thought I would integrate it directly in GH Maps (click "Details").

Try it here.

level of traffic stress (see here and here and here):

rule number	Condition	LTS
1	cycleway: track, separate	1
2	road_class: cycleway, path, footway, pedestrian, living_street, bridleway, track, corridor	1
3	road_class: service	2
4	road_class: steps	3
5	road_class: trunk, motorway	4
6	road_class: primary, secondary + lane	3
7	road_class: primary, secondary + missing + non-rural	3
8	road_class: primary, secondary (otherwise)	4
9	road_class: tertiary + lane + non-rural	2
10	road_class: tertiary (otherwise)	3
11	road_class: residential	2
12	unclassified + rural	3
13	fallback (unclassified non-rural, other)	2

note: table is updated when tweaks happen in master. they should reference to this PR
important note: crossing roads is currently not considered!!

Open questions:

• Should tertiary + cycleway === 'missing' go to LTS 2 instead of 3? Same for primary/secondary and cycleway==missing
• trunk/motorway is always LTS 4 even with cycleway === 'track'. For now probably fine to be ignored as it is rare.
• cycleway === 'no' on primary/secondary is LTS 3 in cities (not according to Furth)

and for foot:

rule number	Condition	LTS
1	sidewalk: yes, separate	1
2	road_class: footway, pedestrian, path, living_street, steps, bridleway, corridor, track, cycleway, service	1
3	road_class: trunk, motorway	4
4	road_class: primary, secondary + missing + non-rural	3
5	road_class: primary, secondary (otherwise)	4
6	road_class: tertiary + rural	4
7	road_class: tertiary + non-rural	3
8	road_class: residential	2
9	unclassified + rural	3
10	fallback (unclassified non-rural, other)	2

TODO

• adapt color in heightgraph (Elevation widget #440)
• separate incline + decline (for now keep it simple and combined)
• add cycleway & footway as path details (see here and here)
• use cycleway & footway path details for bike/foot stress level calculation instead of road class alone

This is awesome! 🎂

Just one minor thing to make it production ready:

Would it be possible to use the same colors in the left statistics and in the Legend? It seems the statistics colors are manually tuned, so these should also be used in the Legend.
