I LIKED the letter by R.J Winter MBE (letters, February 23).
He suggested carrying out a “properly controlled and monitored trial in one area for a period of at least six months”. Unfortunately there is a problem with this. In order to do a before and after comparison we would need an area where accidents regularly take place more than once every six months.
On most residential roads accidents are very rare and a much longer time scale would be needed. A map of the roads in the scheme, showing where accidents have occurred over the previous 20 years would help to choose an area. It would also show what savings could be made with a 100 per cent reduction in accidents. It would also be of interest to show the increase or decrease in accidents where speed humps have been introduced.
I am sure your readers would also appreciate the production of the above map.
