Traffic sensors are devices used to monitor and manage vehicle flow on roads. They collect data on the number of vehicles, their speed, and traffic patterns. This information helps city planners and traffic management systems improve road safety and reduce congestion. These sensors can be found in various forms, including inductive loop sensors, radar sensors, and video cameras. Each type has its own method of detecting vehicles, whether by measuring changes in magnetic fields, using radio waves, or analyzing video footage. The data gathered is essential for making informed decisions about traffic control and infrastructure development.
