A recent spate of articles have been claiming that separate bike lanes worsen air quality. The Guardian refutes this.
Transport for London statistics show that just two weeks after the capital’s two new cycle “superhighways” were open, both routes were carrying 5% per hour more people than previously, a figure set to rise as more cyclists use them. Having given 30% of the space to bikes, these now comprised 46% of people using the roads.
This makes sense when you realise that the standard traffic engineers’ rule of thumb is that a road that can carry 2,000 cars per hour on average can carry 14,000 bikes.
Could the problem not be vans delivering parcels? In 2000, 11% of motor vehicles in London were so-called light goods vehicles. By 2015 this had risen to 14%.
Also, TfL licensing information shows that amid the rise of Uber and its ilk, from 2009-10 to 2016-17 the number of what are officially known as private hire vehicles shot up from just over 49,000 to almost 87,500. That’s a lot of vehicles.
