Using what criteria?

The numbers of those killed or seriously injured are fairly meaningless 
if taken in isolation from some measure of relative levels of use 
between the two years.

If, say, there had been a 50% increase in bicycle use, a mere 6% 
increase in the number of cyclists killed or seriously injured would be 
an overall reduction in the rate of accidents. Similarly, if motorcycle 
use fell by, say 25%, then a 4% fall in numbers would be an overall 
increase in the rate.
