Sensor

I want to make a traffic controller which changes its counter according to crowd. Can anyone tell me which sensor I have to use.

Hi Ronit

Do you have any way of positioning an IR sensor so that the crowd would have to walk through it? This could act very much like the car sensors that are embedded in the road way and prolong the walk signal to compensate for sensor input from the broken IR beam.

If you need accuracy, you could mount a LIDAR, or a LEDDAR or possibly a Kinect, above the path and count heads as they pass below.

Hi Ronit,

Have the Arduino test for the sensor to be active ( people are passing through it) and start a timer that extends the permission to walk by some predetermined amount. This system can be as sophisticated as your ability to program it and the flexibility of the traffic signals to accept control. If these are commercial traffic signals the maker of the signals may already have a metered pedestrian system available.
