Using newly released data from Transport for London's cycle traffic census, University College London Centre for Advanced Spatial Analysis (UCL CASA) Research Associate Oliver O'Brien has created an interactive map showing traffic flows on key routes in central London. The data, collected in around 170 locations earlier this year and acquired by Andrew Gilligan, the Greater London Authority's cycling commissioner, shows the number of cyclists on each route and how this changes over different periods of the day.Click on the drop down menu to compare by vehicle type or by the time of day.
