Traffic Signals Inspired By Bugs

Why does it always seem that when there’s no traffic, a stop light is too long and when there’s tons of traffic, a stop light is too short?

Ozan Tonguz, a telecommunications researcher from Carnegie Mellon, has examined the way ants and termites nagivate their own versions of gridlock to create Virtual Traffic Lights, an algorithm that helps control human traffic on busy streets.
