smart lights

We need them, am I right? I drive to work at 6 am; it's icy and dark. There are 8 lights on my way to work and hardly any traffic. So why, why does the light turn red as I approach? There's no one else around. Why does it randomly turn red? Red for me, green for no one.

Smart lights. They read traffic patterns. Stay green for traffic flow, adjust to volume. That's what we need: smart lights.
