First smart pedestrian traffic signal has been installed on Al Saadah Street in Dubai by the Roads and Transport Authority

The signal uses a sensor-based smart system through an optical ground system.

Using sensors and cameras, the smart signal detects pedestrian movement and controls the traffic flow. Inputs from sensors and the optical system are processed by a computer that also controls the signal lights.

It spots the movement of pedestrians on the pavement before crossing the street or during crossing and automatically modifies the timing of the signal's light accordingly
