NOTES:  The roadway congestion index (RCI) is a measure of vehicle travel density on major roadways in an urban area.,,,,,,,,,,,,,,,,,,,
"An RCI exceeding 1.0 indicates an undesirable congestion level, on average, on the freeways and principal arterial street system during the peak period.",,,,,,,,,,,,,,,,,,,
"The cities shown represent the 50 largest metropolitan areas, as well as others chosen by the states sponsoring the Texas Transportation Institute study on mobility.",,,,,,,,,,,,,,,,,,,
