Waze is about minimizing drive time for the locally for the individual, but that's at odds with minimizing drive time globally. This seems to be about optimizing flows globally, and there's a feedback loop between Google maps and intersection timing. For instance, if the majority of traffic flows east/west through an intersection, then you could expect more time is given to that flow than north/south. This would minimize global drive time, but it wouldn't be locally optimum for people that drive north/south through that intersection.
