Tonight, on my way to work, I saw one of those temp electronic billboards on the side of the road on GA400 (like what they use to notify you of road construction) saying that tomorrow, Sunday, Sept. 26th, from 6am to 1pm (I think) they will be doing "Traffic Pacing" and to expect delays. WTH are they talking about? What is traffic pacing? And what is the point? Anyone? The billboard was just before the MARTA exit, southbound on GA400.
