Cycle campaigners have used open-source collision data to map every collision involving a cyclist between 2005 and 2016. The collision feature is one of the layers of the Bikedata cycle campaign map created by Cyclestreets which is a Cambridge based not-for-profit company run since 2006 by coders Simon Nuttall and Martin Lucas-Smith. Both have long been involved with Cambridge Cycling Campaign for many years.
The Bikedata map is currently in beta, and there are bugs, which are slowly being squashed – for instance, a small number of the reported collisions in London had appeared to have happened in the Thames. Lucas-Smith said: “We believe there’s an offset error with the DfT’s 2016 data which we reported, explaining those in the Thames.” However, these third-party errors have now been corrected, said Lucas-Smith.
The STATS19 collision data sucked into the map is published by the Department for Transport and sourced from the police – it relates to personal injury incidents on public roads.
