from a parish plan for a nearby small rural village divided by a primary route. It seems that guardrail, though less requested than speed cameras and a crossing, is surprisingly popular with residents…
9. Roadside Barriers
Requested by 28% of respondents
The County Council advise that these are of most use when it is desirable to guide pedestrians to a more suitable location at which to cross the road. They are prohibitively expensive and provide no protection to pedestrians from vehicles leaving the road. In addition, in the heart of the village they would be unsightly.
Interesting also that it's "prohibitively expensive". I'd have thought there would be a severely oversupplied second hand market.
