The main reason traffic is so bad in Miami-Dade is not because there are so many people on the road at the same time; it's because most people are on their phones talking, texting, browsing social media, reading articles, navigating gps, etc. Smart phones and social media have made driving a real danger and unfortunately we don't have an abundance of police officers who can spend the day driving around to catch irresponsible drivers. A traffic flow task force is a group of individuals who are trained by transportation experts/law enforcement (like a parking enforcement officer) and have some authority to stop drivers who are are being careless on the road, such as texting while driving. If you notice, when there's a police officer directing traffic at an intersection, it flows a lot better. That's because people are paying attention and on their best driving behavior.
