As the TNCs get ready to roll, there's some local Twitter accounts that give pretty fast traffic updates. I check these as well as use Waze. I created a separate timeline column in my Twitter app, so I can see just the traffic info. Checking in between pings might help you avoid backups. Some I use are: @TotalTrafficLV @RTCSNV @MicahTrafficGuy @KarlManTV @NHPSouthernComm @LVMPD Also, the site http://seeingorangenv.com/ is an up to date map with ongoing road construction. Hopefully this list might be beneficial if you use Twitter.
