I’ve been seeing more and more of these popping up on roads, those thin little cylindrical strips they lay across the road attached to a small box. What exactly are they for? Is it simply to count how many cars cross this point? I assume they do at least that. Do they record information like what time there is heavy traffic. Can they distinguish between cars, motorbikes, trucks, etc? Do they record what speed you’re travelling? Why do they sometimes have two strips about a foot apart?
I’m hoping it means they’re planning on adding an extra lane or something. For the record, I live in Australia if that makes any difference.
