Automated Data Qualification: Our patent-pending process
peridically reviews all the data we publish and determines whether
the data may have been outdated.
Authoritative studies have shown (see Washington DOT, May 2000)
that even the most respected, sophisticated, and expensive traffic
information servers exhibit lapses of time when the information
becomes outdated or unavailable.
If we were simply pulling data and publishing it as is (as most
competitors do) we would periodically relay outdated data, or leave
outdated information published on the present server.
Instead, when our algorithms and software spot an significant
issue with the data, we decide to not publish the suspicious data.
This is why you may infrequently see the speed/congestion information
missing as it becomes outdated. As soon as the up-to-date flow of data
is restored the green, orange
and red dots will re-appear.
