Bartlett Research Finds That One-Sixth of London’s Streets Have Room for Pop-Up Cycle Lanes

Looking at data for every street in Greater London, Bartlett researchers found that 2,357km of streets were wide enough to implement a 2.2-metre cycle lane in each direction, while still allowing room for cars and other vehicles.

If installed, these lanes would increase protected cycle routes from under 2% of all London streets to 16%. TfL guidance recommends that cycle lanes should be at least 2.2 metres where possible.

Among those identified as having enough space were six key roads providing long, continuous routes for commuters heading into central London. These were from Edgware Hospital to Marble Arch (A5); Elephant and Castle to New Cross (A2); Elephant and Castle to East Dulwich (Camberwell Road/A2216); Hackney Central to the Royal London Hospital (A107); and Regent’s Park to Manor House (A503).

Research methodology

The researchers examined the make-up of street space in Greater London to identify all streets wide enough for new cycle lanes.

Nicolas's original analysis of street space was based on data from the Ordnance Survey, the UK’s national mapping agency.

They determined that, to accommodate 2.2m cycle lanes on each side, a road would need to be at least 11 metres wide, giving 3 metres of space in each lane for cars and other vehicles and 0.6m for low kerbs or protective barriers separating the cycle lanes.

The project received funding from the Engineering and Physical Sciences Research Council (EPSRC) and The Bartlett Innovation Fund and was a collaboration between UCL researchers and two organisations, Healthy Streets and Tranquil City.
