According to what I've found out there's only been six fatal accidents
in the borough of Kingston since 2002, an area that contains a large
chunck of the a3. However, the A037 runs right through the area and the
section in the north of the borough is a well-know accident blackspot.
So much so, there's been two GATSO's on one stretch of the road for
several years now. I suspect the criteria can be bent to include any
section of a road in one area whether a particular portion is safe or
not.
