Similar to Google's "popular times" feature for avoiding lines, the new update for the Google MapsAndroid app shows when there's likely to be traffic to a specific destination. It's a simple addition - and one that would benefit from a little more work and refinement - but it's a valuable one for travelers. Now, Google is expanding on that feature by showing how busy the traffic is along your route by the time of day. After all, we can't all afford the new Audi A8 that drives for you when in a jam. When you've tapped in your start point and destination and hit the Directions button, before you choose to start your journey, tap Route Info instead. This will come in handy if you're trying to determine when you should leave the house, and how long you might take because of the traffic.
