Ten cities with the worst traffic
Gregory Alan Bolcer stashed this in Dangerous Decisions
They're metrics are a little off. They should measure it by the *difference* of taking specific freeways during *peak* hour versus non-peak. I was at that exact spot in the picture probably at that same exact time. It took me 1:45 to make a :35 trip. It was painful. That's not a congestion score, that's a multiplier.
Self-driving cars should help this situation. Improved efficiency.
