MDOT's mstraffic (http://www.mstraffic.com/) website has been recently improved. In addition to dozens of new traffic cameras scattered around the state, there's a new feature you can use to save the routes of the commutes you most commonly take. Then, before you leave (or during the trip from a smartphone), you can very quickly check traffic conditions along your route. I haven't tried it yet, and in my town serious traffic jams are rare, but if the feature works well it might be worth a smartphone upgrade just to use it, at least for folks in Jackson or on the Gulf Coast.
