|Am I the only one that thinks that Traffic Pulses use of red, yellow, or green is a waste?
In theory it may sound good. It even makes for a cute little tag line, "XM Instant Traffic, where you'll always know your Jam Factor". But in reality it doesn't really mean anything. They describe it as being "the overall market condition". But without the specifics given in the Jam Alerts and the Comprehensive Report, it's pretty much useless.
The indication they give (say for instance, red) may not apply at all to the highways I take to work. The labels can often be applied at the wrong times too. Listening to the Chicago report I've heard a yellow Factor given when virtually all of the highways were running at posted speeds, as well as a green Factor during the height of rush hour.
If they want to make those labels more useful, why not skip the initial Jam Factor, and use the red, yellow, and green labels in the Jam Alerts section to list specfic problems before launching into the Comprehensive Report. During off peak driving hours focus on those roads that deserve a yellow or red designation and say that the rest of the roads are green. During rush hour periods, focus more on red (severe problems, such as all lanes blocked for an accident) and green (a highway that is experiencing less than expected delays for a rush hour) alerts and say that the rest are yellow, meaning normal rush hour delays
This simple change in format would make much more sense. There's really no need for the Jam Factor in its current use. Anyone else agree?
