Suffix both_ways
Status: Proposed (under way)
Proposed by: Imagic
Tagging: [[Key:<existing key>:both_ways|<existing key>:both_ways]]=[[Tag:<existing key>:both_ways=<existing value>|<existing value>]]
Applies to: Way
Definition: Specify properties for lanes or similar features running in both directions of a way.
Rendered as: Dependent on the base key
Drafted on: 2012-04-26

In analogy with the suffixes :forward and :backward the proposed suffix :both_ways can be used to specify lanes or similar features running in both directions of the OSM way.

Rationale

Currently there exist the suffixes :forward and :backward which e.g. are used in lanes:forward=* to specify the number of lanes in the same direction of the way and lanes:backward=* for those lanes running in opposite direction. We are missing the possibility for lanes/features/properties, which run in both directions.

This suffix could be useful e.g. together with reversible, median or centre turn lanes.

Tagging

Add the suffix :both_ways to the existing OSM key to restrict its meaning to lanes or similar features running in both directions.

Examples

Description Image/Photo Tags
A typical example (marked in red) of a lane for both driving directions in the middle of a junction. Both Ways Example 1.jpeg lanes=3
lanes:both_ways=1
turn:both_ways=left
A typical example of a centre turn lane. HillsideRdCaversham.jpg lanes=3
lanes:both_ways=1
A great example of the creativity of today's traffic planners: the light-grey lane in the middle is a so called multi-purpose lane, which might be used in both directions by all road users, even pedestrians. Vehicles may use it for e.g. turning or accessing buildings. (This is an official statement) Lahr AlteBahnhofsstrasse.jpg lanes=5
lanes:backward=1
lanes:forward=3
lanes:both_ways=1
vehicle:lanes:backward=yes|no
bicycle:lanes:backward=no|designated
vehicle:lanes:forward=yes|no|yes|no|yes
bicycle:lanes:forward=no|designated|no|designated|yes
turn:lanes:backward=none|through
turn:lanes:forward=left|left|through|through|right
access:lanes:both_ways=yes

Current usage

lanes:both_ways=*
turn:lanes:both_ways=*
access:lanes:both_ways=*
