Quick start

pip install lanestyle duckosm[levels]
duckosm build --pbf monaco-latest.osm.pbf -o monaco.duckdb -m driving -m walking -m cycling
duckosm gmns monaco.duckdb -o monaco_gmns.duckdb                # the lanes (GMNS, lanes and turns from SUMO)
duckosm levels monaco.duckdb                                    # the drawing order: monaco.levels, where your edits live

import lanestyle as ls

ls.lane_page("monaco.levels", "monaco_gmns.duckdb", "monaco.duckdb").save("monaco.html")   # one file, opens offline

or python lane_page.py monaco.levels monaco_gmns.duckdb monaco.duckdb monaco.html.

What you get

• The roads, drawn by roadstyle. Each road is one line as wide as its lanes, with its outline, ends, bridges over and tunnels under, street names, hover and click: the drawing of roadstyle's level editor, so a road you fix in the editor (roadstyle-levels edit monaco.levels --items lanestyle.editor:lane_items) is the same on the page.
• Lanes on them. Bus and bike lanes in their colours, lane lines (dashed between car lanes, solid next to a bus or bike lane, a centre line between directions), turn arrows before a junction, BUS and bike marks, all in metres. Car lanes are invisible but clickable.
• Plain junctions. Lanes, lines and arrows stop where a junction begins, as painted on a real road.
• Zebras and sidewalks. Painted crossings as white stripes (from zoom 17); the sidewalks OSM tags on a street as strips beside it. A road cars do not use (a footway, a cycleway) is drawn in the colour of who uses it.

lanestyle draws nothing of its own: roadstyle draws every road, lanestyle only reads duckOSM's GMNS lanes and adds them to the roads as items. Settings (colours, widths, dashes, marks): src/lanestyle/data/lanestyle.json, overridden by a lanestyle.json in the current folder.

For AI agents

• Using lanestyle: the agent skill skills/lanestyle/SKILL.md has the install, the lane table, the one call, the JavaScript API and the traps in one page. In Claude Code: /plugin marketplace add Khoshkhah/lanestyle, then /plugin install lanestyle@lanestyle.
• The docs as text: llms.txt and llms-full.txt (every page, one file).
• Changing lanestyle: AGENTS.md has the layout, the commands and the project's rules.
