Archpaper.com : "Polluting air and clogging roads, vehicles choke our cities. Miami ranks fifth nationally and tenth globally for congestion, as residents spend 65 hours in traffic per year on average, according to INRIX, a global traffic researcher that uses big data. Adding real injury to insult, the state’s stretch of the I-95 is America’s most deadly, according to statistics from the National Highway Traffic Safety Administration.
There is a financial burden to excessive traffic too. INRIX estimates that congestion costs Miami drivers $3.6 billion per year (remember that figure). Additionally, drivers pay out an average of $628,000 every day in tolls, just for the privilege of using the Miami-Dade Expressway."
