A Waze Map Editor (WME) userscript addon to help with junction design.
- When two connected segments are selected, it shows the turn angle between them and predicts the routing instruction Waze will give (Keep Left, Turn Right, U-Turn, etc.).
- When a single segment or node is selected, it shows the angle between each connected segment.
- Draws angle markers directly on the map canvas for at-a-glance reference while editing.
- Install Tampermonkey for your browser.
- Click Install from GreasyFork.
- Visual angle markers drawn on the WME map layer
- Routing instruction prediction (Keep, Turn, U-Turn, Exit, Roundabout, etc.) with color coding
- Override instruction detection (seb-d59)
- Roundabout circle overlay option
- Configurable angle thresholds (Turn vs Keep, U-Turn, gray zone)
- Per-user settings saved in WME
- Multilingual UI (see Translations below)
