That probably does depend on the traffic lights in question. In some 
cities, traffic lights are sync'ed to each other to give some traffic 
what we call a "green wave" in Germany, and/or can be remotely operated 
to give priority to emergency vehicles, so I'd guesstimate that by now 
there /are/ traffic lights somewhere in the world (especially in 
megacities) that are controlled by some central traffic management 
computer system.

(Not to mention that even "stand-alone" traffic lights will typically 
have been migrated from hard-wired relay circuitry to microprocessors by 
now.)
