Description

See Controlled-access highway on Wikipedia

A motorway is a major highway with restricted access to adjacent properties, designed for motorized vehicles, normally equipped with a minimum of four or more lanes. In most cases the motorway is a dual carriageway which means that the traffic for each direction is separated by a central barrier or strip of land.

In some countries, cyclists and pedestrians are banned from using motorways. In others, they may be allowed, at least on rural motorways (e.g. the western U.S.).

Equivalent to the freeway, Autobahn, etc.

Its speed limit depends on local traffic conditions. Some motorways in rural areas have no speed limit while some motorways in densely populated urban areas have a speed limit of 60km/h (40 mph) or lower.

Motorways which do not meet all motorway requirements (e.g. some at-grade intersections) are usually tagged as highway=trunk (depending on the country).

How to map

Map dual carriageway.png

To map a simple motorway you can just draw a line for it. Select all ways which belong to the motorway and tag them with highway=motorway. Make sure the way points in the same direction as one-way traffic goes.

Note: while motorway may technically imply oneway=yes, many of the standard editors and renderers do not handle this properly. Therefore it is common to see a motorway tagged as oneway=yes, and this should not be removed.

In the case of a dual carriageway you should draw one line for each direction and tag each direction on its own. On a single carriageway, oneway=no should be used.

Be sure to place the nodes for each direction next to each other, this gives a much better result when the map is rendered as well as a visual indication that both ways belong together.
