What are the Jam Factor® arrows?
When you look at the Jam Factor bar in our traffic reports, you might notice small arrows pointing to the left or right like this. These Jam Factor Trend arrows tell you if traffic is getting better or worse. Arrows pointing to the left mean traffic is moving toward a lower Jam Factor, an arrow pointing right means conditions are getting worse. A single arrow means it’s changing slowly, two or three arrows indicate that conditions are changing more rapidly. No arrows mean that conditions have been the same for a while and aren’t changing. You can use the Jam Factor Trend to tell if you should get on the road now, or wait a while. If the trend is getting worse you might want to wait until it starts to get better or look at traffic details to help plan an alternate route. If the trend is getting better rapidly, you may want to start your drive even though the Jam Factoris still fairly high.
