OsmLaneVisualizer

A simple tool to show lane attributes of way data in OSM. Data can be fetched from Overpass API, output is created as Html code.

<Advertisment>Support for at least 105 different keys (that's more than a standard US keyboard!).</Advertisment>

The code is free to use under conditions of cc-by-nc-sa (http://creativecommons.org/licenses/by-nc-sa/4.0/)

How to get data

Option 1: Enter a way or relation id, or the ref or name of a relation into the appropriate box and click the "GO" button next to it.

Option 2: Enter your own query or a valid json object (as output by Overpass) into the box "The Query" and click the "GO" button.

If you change configuration (read the mouse-over text for explanations), click the same "GO" button again.

Interpreted Tags

• bicycle[:lanes][:forward|:backward|:both_ways] The values no, designated and official are displayed
• bridge[:name] Bridges are displayed using a shadow behind the lanes, the name is shown
• bus[:lanes][:forward|:backward|:both_ways] The values designated and official are displayed
• change[:lanes][:forward|:backward|:both_ways] Shown as solid or dashed lines between lanes
• destination[:lanes][:forward|:backward|:both_ways] Shown on destination signs.
• destination:arrow[:lanes][:forward|:backward|:both_ways] Shown on destination signs.
• destination:colour[:lanes][:forward|:backward|:both_ways] Used as background color for individual destinations on a sign.
• destination:country[:lanes][:forward|:backward|:both_ways] If the number of entries matches the number of destination's, the country codes are listed next to the destination, otherwise they are grouped at the bottom of the sign.
• destination:distance[:lanes][:forward|:backward|:both_ways] Shown on destination signs.
• destination:ref[:lanes][:forward|:backward|:both_ways] Shown on destination signs. The ref's are listed at the bottom of each sign
• destination:ref:to[:lanes][:forward|:backward|:both_ways] Shown on destination signs. The ref's are listed at the bottom of each sign
• destination:symbol[:lanes][:forward|:backward|:both_ways] Some common symbols are displayed. They are listed next to destination names
• destination:symbol:to[:lanes][:forward|:backward|:both_ways] Some common symbols are displayed. They are listed next to destination names
• destination:to:ref[:lanes][:forward|:backward|:both_ways] Shown on destination signs. The ref's are listed at the bottom of each sign
• foot[:lanes][:forward|:backward|:both_ways] The values no, designated and official are displayed
• highway=motorway_junction Junction name and ref are displayed, if they are located at the end of a way
• highway=(traffic_signals|give_way|stop|crossing|mini_roundabout) Some highway tags on nodes are shown using the corresponding traffic sign
• hgv[:lanes][:forward|:backward|:both_ways] The values no, designated and official are displayed
• int_ref Shown in left column and on signs
• junction=roundabout Roundabouts are marked
• lanes[:forward|:backward|:both_ways] Used to determine the number of lanes. Might be overruled by other tags
• [maxspeed|minspeed]
• [maxspeed|minspeed][:lanes][:forward|:backward|:both_ways] Supported, shown on left-hand side. Displayed inside lane for lane dependent tags

• turn[:lanes][:forward|:backward|:both_ways] Rendered by using Unicode characters.
• width[:lanes][:forward|:backward] Used if enabled

Number of Lanes

The number of lanes is determined by reading all tags of way containing a :lanes part and the lanes tag itself. For both forward and backward direction, the maximal number is used - this might not be the intended number of lanes but helps to find tagging errors (e.g. stray pipes).
