[Martin Cassini]

In a report reminding us that poor air quality is responsible for 4000 premature deaths a year, BBC London News didn't mention traffic signals as a congestion cause and pollutant accelerator. Nor did the GLA's environment adviser mention traffic system reform as a route to better air quality, despite evidence (No Idle Matter) that traffic lights are a major source of added air pollution.
