A new study by the Transport Research Laboratory in Crowthorne, Berkshire, has shown that introducing traffic-calming measures will not necessarily increase pollution. It had been thought that emissions of pollutants such as nitrogen dioxide could be increased ten-fold because these emissions increase when cars travel slowly. In tests involving 20 cars on Hampshire roads before and after humps were introduced, measurements taken indicated a slight drop in emissions both inside and outside the traffic-calming area. The reason for this is that drivers using residential streets as a short cut have to stop and start at all the junctions. When humps forced them back to the main roads, smoother traffic flow cut car emissions. Although they are effective at slowing traffic in residential streets, the Hawk has always found trafficcalming measures have sent his stress levels skyward. This is partly due to Foden the dog getting the right hump when he is bounced from his canine slumbers in the front seat
