In the upcoming version, waze will take Twitter integration a step further, as this version will feature geo-tagged tweets right on the waze map. This means that if someone tweets that they’re stuck in traffic, it will appear almost immediately on the waze map with a road report pin along with a little ‘t’ icon to indicate that the report came from Twitter. Incorporating tweets onto the waze is going to expand our coverage of real-time road events significantly, plus, the coolest part is that the Twitter integration functions two ways – once you input your Twitter details under ‘Settings’, you’ll be able to respond directly to tweets (on waze and Twitter, simultaneously) by commenting on the road report, turning waze, essentially, into an on-the-go Twitter client.

So what we need is traffic related tweeting services in the various states and/or countries that we can tap into them and add their relevant information. If you are aware of such services, please list them here in this thread and we'll check to see how to add them.
