Last updated
Cause and effect values are calculated by matching text strings within the header and body of the alert.
If any of the text under 'matched text' is found, and the additional criteria (if relevant) is met, then the cause or effect is assigned to the alert. These rules are evaluated in the order shown - if a match is found, no subsequent rules are evaluated for that property.
If no cause or effect are defined, they will not be published in the GTFSR output.
