It is not just a matter of traffic throughput. Part of the purpose "complete streets" movement is to enable pedestrian and other slow-moving traffic for the purpose of increasing or preserving the vitality of urban cores. You have a different "kind" of downtown when it has enough foot traffic as opposed to people zooming by at 50 kmh pissed-off about looking for parking or trying to get home asap. If the metrics only measure throughput of bodies past intersections, they're missing a large part of the point.
