Delays as standard

Sir, – “Standard traffic delays” are constantly referred to in the AA Road Watch reports on radio.

When I used to drive in Dublin we expected the usual delays and, as time went on, these became the normal delays. In modern Ireland such hazy terms obviously no longer suffice and it has apparently become necessary to adopt standards. What are the criteria by which traffic delays are arranged in order of severity? Is there a chart in some technical publication that the ordinary driver can consult so as to interpret the necessarily terse AA reports? – Yours, etc,
