I am not sure what point your article (‘Diabolical’ road for bus drivers, October 10) was trying to make, but comparisons of the raw accident figures for the routes serving Kingston are meaningless without taking into account the frequency and length of the routes concerned.

To suggest that school route 691 or Shopmobility route 965 are “safest”, simply on the strength that they have each recorded just a single accident in the past eight years, is to ignore the fact that the 691 runs just one round trip a day, on school days only.

The 965 runs just two round trips a week – a one-way journey time of about 30 minutes.

Compare this with route 57, that runs 149 round trips a day, each taking more than two hours.

Of course, there are fewer accidents involving 965s than 57s – just as there are fewer accidents involving Ferraris than Fords.

And the sentence suggesting that the three routes with the most accidents all go through Eden Street is misleading.

Nearly all the routes in Kingston, including the two with the least accidents, go through there.
