If it was only averagely dangerous it might still have a higher total than most others because of its length. What you need is figures per kilometre, and even then you would be getting a not very useful amalgam of stretches of road with different risk levels, only useful if you intend cycling all of it. And the danger level of a road must be done by kilometres cycled. A road that sees a few fatalities but has few cyclists using it must be more dangerous than one that has the same number of fatalities with higher usage.
Agreed. I don't think these figures tell you anything useful about these roads. As PWA points out, you also need to know the levels of cycling.
There are (at least) two other problems with looking at accident reports.
1) With low levels of cycling in most areas of the UK, there are actually very few cycling related accidents at any particular junction or stretch of road. You can make general conclusions, for example, that accidents tend to occur at junctions, or some types of road are more dangerous than others.
I do not know this area. The A6 is described as the most dangerous road in Lancashire for cycling, with 22 serious accidents in 3 years on about 45 miles of road (please correct me, if I have the distance wrong). Or, 1 serious accident per mile every 6 years. On average. Or an accident per 1/4 mile typically every 24 years. It's unlikely that accidents will be evenly distributed.
How can the A6 be made safer for cycling? I suggest that accident data is unlikely to help decide this, unless there are places with lots of accidents (at least a few per year).
Contrast this with general road accidents.
Looking at https://www.crashmap.co.uk/Search
for Basingstoke, you can see that every major roundabout has has many accidents (over the past 5 years). Some more than others. So, planners can see which places would benefit most from safety improvements.
2) The other problem with accident data is that cyclists avoid what they think of as the most dangerous roads. Again, looking at Basingstoke on crashmap shows that most of the large roundabouts had no cycle accidents. Nor did the dual carriageway ring-road have many. Do you conclude that fast dual carriageways and large multilane roundabouts are safe for cycling? Or perhaps cyclists avoid these?
