Traffline gives you real time traffic condition information in brilliant colour-coded lines (green for Smooth, red for Congestion, and so on). Of course, we know, you want more. Under the category of 'Alerts', you can also find out what's causing the jam in the first place. And if you figure it's a BEST bus, again, don't tell us we didn't tell you so. Available on iOS, Android, BlackBerry platforms, free.
