Line of argument

I was attracted to your story Fewer white lines could improve road safety (NCE 21 July) as I have been wondering about simpler, cheaper, less environmentally intrusive and more helpful speed limit indicators for some time.

Many of us fi nd the inconsistencies in speed limits frustrating and distracting: what is 30mph in one county could be 40 elsewhere, and vice versa. The variations along a length of road can seem to bear little relationship to alignment, road width, adjacent property, apparent hazards or other activities etc.

I would therefore like to suggest a further refinement.

In a 30mph limit three distinctive short, perhaps wriggly, coloured lines be inserted in the edge or centre line at regular intervals; in a 40mph limit, four lines;

and in a 50mph limit, five lines. Nothing is needed in 60 and 70mph limits as 1 or 2 carriageways and the absence of anything else indicate the limits there.

Existing signs at the start and end of each speed limit length of road are retained.
