Traffic Data Collection is the process of gathering and analyzing information about how vehicles and people move on roads and highways. This includes counting vehicles, measuring speeds, and understanding travel patterns. Transportation professionals use this information to make decisions about road improvements, traffic signal timing, and safety measures. Think of it like taking the pulse of a road system - it helps engineers understand where improvements are needed and how well current solutions are working.
