SIR: I walked along the improved pedestrian route in Jewry Street only to find I had to turn back because the road was packed from end to end with stationary cars pumping out pollution.

I am wondering if the traffic engineers could devise a system of traffic lights etc. so that drivers wishing to enter the city were queued in a place where pollution would cause less of a problem and they could be encouraged to turn off their engines while waiting.

I think it could be done by simply controlling the number of cars entering and leaving the inner city roads as is done with car parks.
