SIR - A recent report by the London School Of Hygene and tropical medicine, published in the British Medical Journal shows that the introduction of 20mph speed limits in London has cut road injuries by 40 per cent, preventing 700 casulaties in London alone.

After adjusting for a general reduction in road injuries in recent years, they found that the introduction of 20mph zones were associated with a 41.9 per cent drop in casualties.

The greatest reduction was seen in children under the age of 11 years and in the numbers of all ages killed or seriously injured.

Cyclist injuries fell by 17 per cent once 20mph zones came in, and injuries in pedestrians have been cut by almost a third.

There was also no evidence of a higher rate of casualties in areas bordering the 20mph zones, as in areas adjacent to 20mph zones casualties fell by an average of eight per cent.

Given this evidence, when will Herts County Council introduce these limits in St Albans?

SIR - With reference to Mr Leman's letter (Herts Advertiser, December 3) in your columns, he may well be right in some circumstances but wrong in others.

A 20mph speed limit on market days in St Albans is not unreasonable but if traffic and pedestrian conditions allow, 30mph is not unreasonable either.

Mr Bridgstock in his letter in the same edition is also right. I have experienced the same situation myself of cars overtaking me due to frustration that the road had few danger spots at the time I was travelling. The effort of travelling at 20mph uses more petrol and thus more CO2 and other gases due to the fact that there are more revs on the engine due to selection of lower gears on many cars.
