A free app that's light on the options but useful for drivers, U.S. Traffic highlights routes in different colors to show the level of traffic in an area. Upon opening the app, users are asked to enter a location or select an option to set Traffic Report Preferences. Selecting a location does not immediately take you to a map view; you have to press the back button, which I found clunky and odd.
You can use the My Location option in the menu to pinpoint your position on the map. Road construction is represented on the map by yellow cones; tapping on the cones pulls up information about the obstacle. Tapping the list icon on the bottom right of the screen will pull up information on road closures, collisions, or other issues in the surrounding area such as "Road Construction on Taraval Street" or "Disabled Vehicle at Powell Street." The map itself displays red, yellow, or green lines overlaying streets to show at a quick glance where traffic is heavy, moderate, or moving. Zooming in provided the flow of traffic from street to street. The only thing that's missing from this app is information on the best detours around traffic or information on how to avoid obstacles. Even without that, this app performs steadily and quickly proved itself to be useful.
