Bicycle LTS assigned to stairs #194

I noticed that edges with the STAIRS flag also have a bicycle LTS attached.

I'm not sure if this is a bug or not based on my Traffic stress understanding. But during traverse STAIR_RELUCTANCE_FACTOR (3) is multiplied with weight if stairs are used if walking is used WALK_RELUCTANCE_FACTOR (2) is also multiplied with weight.

If this is wrong it can be easily changed.

LTS 1 is definitely wrong. Have you ever ridden a bike down a flight of stairs? It's terrifying.

abyrd commented 7 years ago

Stairs don't cause traffic "stress", they are just slow and require a mode switch, and those penalties are still applied. @buma and I were thinking this is sufficient to discourage stairs from appearing in routes.
