It's not only at round abouts'. you can see it on may busy roads. Its to count the number of vehicles passing through that way. So, the authority can do appropriate traffic changes on these roads depends on the survey.
If you approach them too fast they spring up and stop you. Like on an aircraft carrier. It's the new way to slow speeders down.
