Sorry, I should have made it clearer - the 'badness' is measured by casualty stats collated, they are the locations with the highest number of cycle collisions in the GLA area between 2008 and 2010.
TfL's spiel, in MQTs was that these were all "heavily cycled areas" and therefore the injury rate was commensurate with the volume of cyclists - as if that was somehow inevitable and okay(!)
