From that perspective, it seems like madness to suggest that cars should be forced to stop and idle repeatedly during the night on the offchance that a pedestrian might be waiting to cross. A pedestrian idling for a few minutes (assuming they require the guidance of the "green man" and are unable to assess the safety of crossing themselves) has much lower impact.
