Waiting for nothing

I think that what frustrates me the most about driving in Lexington is waiting for nothing. I spend an inordinate amount of time sitting at red lights while no traffic goes in the other direction. Invariably, about the time that my light turns green, cars start arriving at the perpendicular light, in order to wait while one or two cars go through the other way, and they they, too, wait for nothing, for another 2 or 3 minutes.

Surely *someone* has studied the mathematics of traffic lights and can make intelligent decisions about how lights should work so that this doesn’t happen. Indeed, in other cities, I don’t experience this sort of thing. It seems to happen only in Lexington.

What’s up with that?
