All, for those of you wondering about traffic in the Charlotte area, this may help a bit. You will get a small sample of the traffic on I-77 north and south of the city at
Click on the Metrolina area for Charlotte and float your mouse over each traffic camera (when they are working) to have a pop up window open with a real time still shot of the traffic in that area. Double click on the camera to have a smaller view with 4 pictures with north/south/east/west views (when they are working). This also helps you to see which direction the camera is facing and which direction the traffic is heading.
From my observations, it is a so-so indicator of the traffic south of the city because I never see heavy, stand still traffic. It seems to be a good indicator of traffic north of the city because I often see heavy, slow or stand still traffic. Unfortunately, they do not have cameras on any secondary roads in the area. Maybe a local can weigh in on the accuracy of this.
They also have camera sites for the Triangle and the Triad.
