Jon,

Here in Canada, we have those pedestrian clocks too, but, in many cases, there’s not much of a relation between when the traffic light goes green and when the pedestrian clock reaches 0.

You need some electric motors, wire, sheet metal, screws, and paint…

Eric -

You see countdown timers on pedestrian signals now very frequently in the States, so they know how much longer they have to get across and the drivers know when to start revving their engines.

In several Chinese cities, countdown clocks beside vehicle traffic signals (but interestingly, not pedestrian walk signs) are common at super-congested intersections.

Did they use Xcelsius to make that? ;)

Derek – That sounds like the traditional colored light signal. I think that would eliminate the benefit of seeing the overall cycle, without eliminating any of the drawbacks.

I would have preferred that instead of the colored disk being fixed behind a rotating indicator, the disk had rotated behind a fixed mask, so that only one color was visible at a time.
