Traffic sensors or traffic light sensors are devices which are used to manage inconsistent traffic flow efficiently. Traffic sensors also detect if cars have entered turn lanes, cars have arrived at intersections, or cars are stacked at intersections. Usually in large cities, traffic flow is dictated by traffic lights with the help of timers; but traffic signal sensors are majorly used in up county roads and suburbs as traffic flow is less consistent there. There are numerous technologies which are used in traffic sensor devices such as infrared, radar, lasers, rubber hoses, video detection, piezoelectric and inductive loops. Inductive loops technique is the most commonly used technique owing to its simple structure and its advantage that it does not get affected by weather conditions. Inductive loops are coils of wire that are rooted under the road surface to detect changes in inductance as vehicles pass above it. When the car stops over the buried coils, the car’s st...
