Well, it kind of does, but definitely not the worst.
A few words about the index:
Number-crunchers at IBM Research surveyed 8,192 motorists in 20 cities, and â€” no surprise â€” most of them think traffic has only grown worse during the past three years. More than half said gridlock has wreaked havoc on their physical or mental health. One-third said it is undercutting their productivity at work or school…
…IBM used the results to compile a â€œCommuter Pain Index,â€ which ranks the emotional and economic toll of commuting. The index is a measure of 10 criteria, from the amount of time spent sitting in traffic to the frequency with which people simply gave up and went home.
