@VincentStops@willnorman Neither study proves Β£1.5bn was value for money. That requires a comprehensive economic appraisal.
But nor can you conclude Β£1.5bn achieved "very little" simply because London-wide casualties increased.
@VincentStops@willnorman Agreed. The increase in serious injuries deserves investigation. But rising London wide KSIs don't establish that individual safety schemes have failed.
We need to examine collision types, locations, cycling exposure and changes in risk, then compare treated roads with controls.
