You have had the dictionary definitions of dangerous from three dictionaries and roads are covered nicely by all three.
EuroRAP (the European road buttessment program) uses the term "dangerous roads", they have nothing to weasel out of.
Taken from the 2005 EuroRAP report: "Risk-rates for Britain's most dangerous roads are higher by a factor of 10 when compared to the safest sections."
"It is said that there is no such thing as a bad road, there are just bad drivers. That view overlooks the fact that even the most skilful driver or biker can make a mistake - and the price he or she pays is all too often rest or disabling injury. It need not be so. Simple engineering measures can often improve a road so that if a collision does happen, the forces involved are reduced.
If we could raise the standard of Britain's roads to perform as well as the average for each road type, the annual toll of bane and serious-injury collisions could be reduced by about 1,400 (20 per cent). This would save about 200 lives and 1,500 serious injuries each year."
When you look at the most improved roads you notice that virtual all have had major reworking:
M48 - Avonmouth - signing and lining. (77% reduction)
A49 - Kidderminster - junction improvements; signing and lining; traffic signal improvements. (74% reduction)
Coventry ring road - Extensive route action (eg, grade separated junction; signing; anti-skid). (72% reduction)
Now are you going to say that the changes haven't made the roads safer?
NIP arrived. 971Following up to Mark Foster but you are going too far the other way. I agree. BTW I also rather wonder how often "lost control" is accurate...
When you look at all the top risk roads one thing is very clear they are all single carriageway with poor visibility.
