Speed Trap?

So, today is the start of my three day Holiday and we were on our way to Teluk Intan. My colleague has received an E-Mail with pictures saying that the NKVE Sungai Buloh Bridge has some cameras installed. So, I decided to stop by and have a look at it myself.

Shot this at the edge of the cliff


This is from the "Burger King" side and somehow,
I don't think they are for traffic monitoring

These cameras are aimed at the vehicles going towards KL

So, are they speed trap cameras or what? There were signs on the Highway dividers (installed years ago) stating this is a speed trap area. We can usually spot the Policemen manning the cameras under the bridge but nowadays, they have disappeared and these cameras appeared. What do you think?
