Abstract
The present lighting system adds detection capabilities to perceive the presence and measure the velocity of objects such as automobiles, trucks, pedestrian and other users, to lighting modules for transportation applications like traffic signal, pedestrian control, rails signal, street light, message board and speed monitoring board. For example, a Light Emitting Diode (LED) has the capability to be used as lighting source for illumination as a first function and also be pulsed or modulated as a source for the detection sub-system as a second function.
