At a junction it might be a solar powered air quailty monitoring device? Job to know really, as all sorts of things can be solar powered. Road signs included

They ARE solar panels, used for road signs that flash a message like "too fast" or "30" when a car is detected at a higher speed.
There are even a few around with little wind generators on them !

We've got one in a layby between two nearby towns that powers the BT phone box.
