Countdown timers for traffic lights.

I'm sure you've seen those countdown timers for walk signals. There are a number of them around in the States. I'm not sure how places decide where to install them.

Here in Bangkok, they've installed countdown timers for the traffic lights at some major intersections. I'm not entirely sure why. On the one hand, I suppose having a bright red "15" next to the red light, counting down to "14", "13", etc. might get one to wait more patiently. On the other hand, seeing a red "89" counting down might encourage one to run the light. And I'm not sure which a yellow "3" encourages.
