I found out today that in the past month, Derbyshire CC, not content with wrecking the A515, have also reduced the speed limit on their section of the A57 Snake Pass road from NSL to 50 mph. This led me to wonder where all this was heading.
According to the new
DfT guidelines on speed limit setting, the following criteria should be used for setting speed limits on rural single-carriageway roads:
Quote:
Upper tier A and B roads
• 60 mph: high quality strategic roads with few bends, junctions or accesses. When the assessment framework is being used, the accident rate should be below a threshold of 35 injury accidents per 100 million vehicle kilometres.
• 50 mph: lower quality strategic roads which may have a relatively high number of bends, junctions or accesses. When the assessment framework is being used, the accident rate should be above a threshold of 35 injury accidents per 100 million vehicle kilometres and/or the mean speed already below 50 mph.
• 40 mph: where there is high number of bends, junctions or accesses, substantial development, where there is a strong environmental or landscape reason, or where the road is used by considerable numbers of vulnerable road users.
• 30 mph: should be the norm in villages where appropriate.
It is not difficult to see in a few years' time that we will reach a situation where the vast majority of "normal" rural A-roads have 50 limits, with 60 being confined to limited stretches of new-build roads, bypasses and roads that have been substantially upgraded, such as the A361 North Devon Link Road and the A303 Ilminster bypass.
Yet there will still be a sprinkling of minor A-roads and B-roads that have not been reduced simply because the local authorities haven't had the time or money to get round to them yet, and most unclassified roads that realistically they never will.
So we will have the absurd situation where there is a "reverse rural speed hierarchy" with, broadly speaking, the lower quality roads having the higher speed limit. And the countryside will be blighted with vast numbers of expensive and unsightly speed limit signs.
What a wonderful policy
If you were starting from scratch arguably it would make more sense to follow the Irish approach of having 50 mph as the default rural limit and specifically signing a higher limit on those roads appropriate for it. Obviously I and most others here would vehemently oppose such a retrograde policy, but at least it would have a certain amount of logic and consistency. At present the government are avoiding any open debate on the subject and, effectively, are introducing a 50 mph single-carriageway NSL by stealth.
