An academic study in London shows that painted advisory cycle lanes increase the risk of injury to cyclists by 34%, as against no infrastructure at all.

The research by Thomas Adams and Rachel Aldred, titled 'Cycling Injury Risk in London: Impacts of Road Characteristics and Infrastructure', also found that protected infrastructure reduces the chances of injury by 40-65%.

The key findings of this work are:

Safety in Numbers

The researchers were able to confirm the existence of a 'safety in numbers' effect, with a doubling of cyclists resulting in a 13% reduction in the chances of being injured.

A higher density of pedestrians increases the risk of injury (by 6%), as does a greater volume of traffic (but only marginally).

The researchers conclude that cycle infrastructure on main roads and at junctions must have physical protection, not just paint.
