Any one who commutes in major cities knows the value of back roads when it comes to avoiding traffic on the highways during peak rush hour times. Google Maps just added a nifty feature that will show you live traffic conditions on arterial roads (non-highway roads) in selected cities. Google Maps will also show traffic patterns on main highways as well, helping you see what the least-trafficked route is for your commute.

When you zoom-in on the city you’re interested in and click the “Traffic” button in the upper-right corner of the map, you’ll see the traffic conditions of both arterial roads and highways. The colors correspond to the speed of traffic green is little to no traffic, yellow is medium congestion, red is heavy congestion, and red/black is stop-and-go traffic.
