This proposal seeks to add a visual lane editor to iD. This lane editor must fit in
350px wide side pane of the editor and should be similar to the restrictions editor in terms of functionality and UI. The lane editor should be context sensitive and should automatically get invoked whenever a user selects a highway. It should also provide a simple and intuitive way to add or remove lanes, adjust the type of lanes (eg. forward/ reverse, turn left, right and common conditional lanes like ‘bus’ or ‘HOV’. It should also be able to interpret the existing OSM data for the lane and must conform to the guidelines established by OSM.
