The road signs plugin offers a dialog for selection of traffic signs from a list of presets. With simple clicks you can create combinations of signs and generate tagging suggestions.
How to install / launch
See this page for basic installation instructions. Once JOSM has restarted, make sure you have the properties dialog open and some objects are selected. Then there should be a small button in the upper right corner of the properties window that launches the dialog.
Click on a sign in the left area to add it to the selection. Recommended supplementary sign are shown on the right and can be added to the main sign by left click. (Note: The gray/disabled sign are selectable as well. Use at your own risk and check the results.)
When selecting very common signs and sign combinations, it should be save to accept the tagging suggestion. However you still need to take care of some basic things like adding the right highway=* tag (if not set by the plugin) and choosing proper direction of the way for incline=* and oneway=*.
See the README file. it contains documentation on how to install the customized preset file and make images available.
The first and (currently) most comprehensive preset is the one for German traffic signs. Presets for Poland and Slovakia are available as well. If you like to improve an existing preset or create and maintain a sign preset for your country, you can open a ticket on JOSM trac and attach the files. You can also contact the author directly.
