Stopping and restarting

James Tate of Leeds University appeared in a One Show item last night about the added air pollution from traffic stopping and restarting. Apparently, it boosts the production of poisonous nitrous oxide by cooling catalytic converters which are most efficient when hot. Not once did the item mention traffic signal control, the primary cause of traffic stopping and restarting. Many of our social, environmental and economic problems from traffic are amenable to the Equality Streets treatment, but is anyone listening?
