left-right-hand-traffic
v13 v14 1 1 [[TranslatedPages]] 2 2 = Left- and right-hand traffic = 3 JOSM has an internal database of areas with left-hand traffic. This was added in version r7193. This is used in some [[Styles/|Styles]] for correct display. Examples are the default internal mappaint style (for cycleway lanes and tracks on highways or roundabout icons) or [[Styles/Maxspeed]] (for maxspeed:forward and maxspeed:backward). It is also used for the create circle action, to use the correct way direction, if you create a roundabout (r8303). 3 JOSM has an internal database of areas with left-hand traffic since version r7193. 4 5 The database is used e.g. in the following places: 6 * The default internal mappaint style (for cycleway lanes and tracks on highways and roundabout icons) 7 * [wiki:Styles/Lane_and_Road_Attributes Lane and Road Attributes] style 8 * [wiki:Styles/Maxspeed Maxspeed] style (for maxspeed:forward and maxspeed:backward) 9 * For the create circle action, to use the correct way direction, if you create a roundabout (since r8303). 4 10 5 11 You can download the data [http://josm.openstreetmap.de/browser/josm/trunk/data/left-right-hand-traffic.osm here] (click on ''Original format'' on the bottom of the page) and load the file in JOSM to investigate the borders. The areas in the file describe the areas with left-hand traffic. All other areas use right-hand traffic. 6 12 7 You can use the pseudo classes `:righthandtraffic` for right-hand traffic and `!:righthandtraffic` for left-hand traffic or the eval expression `is_right_hand_traffic()` in your mapcss mappaint style. See [[Help/Styles/MapCSSImplementation]] for more information. Note that you maybe get wrong results near to borders of countries with different driving directions since the area borders of left-hand traffic are simplified in JOSM. These simplifications are necessary to reduce the size of the database, but it can be refined on request.13 You can use the pseudo classes `:righthandtraffic` for right-hand traffic and `!:righthandtraffic` for left-hand traffic or the eval expression `is_right_hand_traffic()` in your [[Styles/|mapcss mappaint style]].
