I just signed up for the traffic API and have been doing some testing against the Denver metro area.
I noticed the "delayFromTypical" and "delayFromFreeFlow" values seem to always be zero, for example in this query:
The documentation does say those values will be zero if not supplied by the traffic provider. Is that what's happening in this case? I was kind of surprised because in an area the size of Denver I would've expected to see some non-zero values.
If the traffic provider really doesn't provide that delay information, is there a good way on my end to determine how bad an area really is? On your map interface you color-code areas yellow or red to indicate the degree of impact from congestion, etc. Can I do something similar using the "severity" value I get back? Is that essentially what severity indicates?
