Here in CA (at least silicon valley) approximately all traffic signals have sensors (it always catches me by surprise when I drive in other states and find there's no sensor so I have to wait endlessly for a green light).
But sensors are nowhere near a substitute for the efficiency of a traffic circle. With a traffic light with sensors you still have to stop for a short time, so it has all the disadvantages of a stop sign and none of the benefits of a traffic circle.
- toast0 6y agoDepends on the sensors. I've certainly driven on streets where the far back sensor is far enough back that it can change the light before you need to slow down (it helps if it keeps all the lights red when the intersection is idle). If you only have sensors at the line, then yeah, you need to stop.
