I exclude waiting at lights when I compute my "average speed". (Actually my computer excludes that time automatically.) I don't have control over it so there's no point penalizing my times for it, although I do get penalized for start and stop times, and any slow rolling.
Please clarify whether you mean pedaling average or trip average. I (used to) routinely get 19-20.2 mph pedaling averages over a 10 mile commute with 17 lights.
It that's not what the OP meant maybe I'm off topic.
