This Diary Post and a comment prompted this question:

"I've attempted to map speed limits, but I rarely find myself walking down a trunk road, and I never try and map whilst driving! If anyone can tell me how they map speed limits I'd be very interested in helping."

I have found a few apps (android in my case) that will control the phone camera and take an image at a voice command. I will report back if i find one that works for me.

If your question is "How To" then either stop to make notes where the speed limit changes (though you might class this as a distraction), or use a dashcam or something like Mapillary or OpenStreetCam and check for changes when you're stationary.

I don't know what the current status is, but Scout at least had a prototype of real time sign detection in their mobile app:

I created a custom set of buttons for OsmTracker that has a button for each of the normally encountered speed limits in my area all on a single (default) screen. I can just tap the appropriate button as I pass the speed limit sign.

Custom speed limit buttons

If desired, I could post the file and its associated button images but they are for US style MPH signs. No reason the concept couldn't be applied to other countries though.

Hi Andy / Ed, What about the good old Dictaphone with a tape or digital, both hands on your wheel, but the pain comes later, listening to rumble or nothing between traffic signs, although quality of a surface is easy to mark in the meantime. Mark/describe the place/situation well.
