I have seen many controlled intersections that have one (or more) left turn lanes with one (or more) straight-through lanes with separate signals for the left turn lane(s) versus the straight lane(s). In general, those intersections are designed to have straight-through traffic going from two opposing directions and then alternate with left-turning traffic going from two opposing directions. When the straight-through traffic is passing, why do the left-turning lanes get a red circular light rather than a green circular light or a yellow circular light? [more inside]
I live in San Diego, and I hate the traffic lights along a particular road that I always drive on (Genesee Avenue). I'm regularly astonished at how soul-crushingly stupid they can be, and I'm constantly yelling at them from my car like an idiot. What can I do about this? My dream would be to talk to the traffic engineers in my city, really pick their brains and offer my observations. How does one go about making this happen? [more inside]

I'd like to ask a relatively simple question – what would happen if we switched of traffic lights when we didn't really need them? I'd like to know from an environmental aspect what effect turning off the nations traffic lights would have towards saving electricity and reducing emissions. From a social point of view could the nation's road users manage with such a change? And from a technical innovation view point – could it and should it happen and if so how?
How does the button on the pedestrian crossing lights work? Does it actually send some sort of signal to the traffic lights, or is it just a psychological thing? It seems rather random timing-wise.
Why do the traffic signals at a particular intersection have light-blocking louvers on them? [more inside]
Traffic lights no longer flash in the wee hours. Why? [more inside]
Wireless Filter. I'm trying to make a Linksys BEFW11S4 v4's Internet light stop flashing so insanely. It's affecting internet speed in a big, big way. [MI] [more inside]
