The 30th November transport for London Programmes and Investment Committee contained a paper entitled, "Update on the implementation of the Quietways and Cycle Superhighways programmes". The paper says, "Other [post-launch] benefits will rely on performance and functionality of new infrastructure and can take longer to obtain sufficient data for comparison to the baseline, these include cyclist usage figures and collision analysis, which are planned to be measured from 2017 onwards". Please you provide further details on what collision analysis TfL intends to do and why it is only being measured from 2017?

Transport for London (TfL) holds data for traffic collisions that result in personal injury that are reported to the police, which is published on the TfL website.  In order to have data that is statistically relevant and to enable any trends to be identified this is typically reviewed using 36 months of post-implementation data.

Cycle Superhighways such as the East-West and North-South routes, plus upgrades to the original four routes, were launched in 2015 and 2016.  Therefore, unfortunately TfL does not currently hold 36 months of post-implementation collision data. However, this will be analysed when the data is available. TfL would be happy to provide the pre-implementation collision data files if this would be of interest.
