Research finds air pollution worse for drivers than cyclists on London roadway

by CyclingTips

In a reversal of conventional thinking, researchers found that air pollution on a London roadway is worse for a taxi driver than for a cyclist. The idea that being tucked away in a car with the windows up makes a driver safer is countered, particularly when sitting idle in traffic, since the tail pipe from the vehicle in front is at the same level as a car’s air intake.

“Being in a car is not like being in a sealed box,” said Professor Gavin Shaddick of the University of Bath. “Winding up your windows may give you the perception that the air isn’t coming through the windows and that you might have reduced your exposure to air pollution, but the intakes for the car’s air system are at the front of the car. And the problem is, they’re generally at the level of the exhaust pipe of the car in front of you.

“The advantages of cycling, of course, are that you are getting health benefits from actually having exercise and it’s been shown that that would outweigh the harm that would be caused by breathing in bad air.”

Pollution levels in the British capital have been of concern in recent months, with the mayor Sadiq Khan telling residents to act to protect their health from the “shameful state of London’s air.”

A Canadian engineer recently calculated the optimal speed for a cyclist to to minimise the level of pollution.
