At intersections with traffic lights there are usually metal lines under/at the surface/imbedded(?) in the pavement where cars stop at the light. I think they somehow detect if a car is stopped there, and therefore, time the light somehow. At a newly built road I have seen multiple lines radiating out from the curb, crossing all lanes, including the left turn lane. How do they work and how do they "install" the system after the road is built? Thank you for responding.
