ImproveOsm is a JOSM plugin to help you improve the OpenStreetMap by pointing at probable missing geometries (roads, parking, path and water trails), missing traffic flow direction or missing turn restrictions. This plugin is grouping the functionalities of the previous Missing Roads and Traffic Flow Direction plugins and is adding the Missing Turn Restrictions functionality. This allows community members to use just one plugin to get access to all the suggestions about possible missing map elements that we share with the OSM community.
