I posted this topic years ago and it was lots of fun. What we do is pose this question: Technology X exists and would easily solve problem Y, so why isn't it being used? And we'll all discuss it until we figure out we're wrong about how easily X can solve Y, and we'll feel dumb. Or we'll figure out that X really can solve Y, but the problem is some failure of society, and we'll feel smart.

First thing: Traffic light preemption. Cheap directional signaling devices have been around for 60 years. And now we even have a sophisticated information network. I haven't been able to find how widespread traffic light preemption is, but why isn't it everywhere by now, at least for emergency vehicles? It should be so cheap and easy.

Spermus, I live in the second least populated capital city of a country that has 1/13 of the population of America and traffic light preemption is in use here. Maybe we could start by establishing how much of the developed world actually uses it. Maybe it is more widespread than we think.

Yeah, Vancouver uses traffic signal pre-emption for its emergency vehicles, and a lot of other Canadian cities use similar technology.

I live in northeast Pennsylvania and I'd say about 50% of the lights in and around my town have signal preemption. I first learned about it in high school, which was five years ago, when my friend showed me that I could skip the light by flashing my high beams.

Flashing your high beams to skip the light is fake.

You've been flashing your high beams at red lights these past five years, haven't you.

I live in Terre Haute, IN, pouplation 60K, and preemption seems absent on the main streets. I concluded the town doesn't have it at all.

Here's an article with some useful facts. Apparently the cheap and common ones cost from $20 to $500. Now I just need to know the price of a traffic signal.

Also:

Quote
A 2002 Department of Transportation survey found pre-emption systems in use at nearly 25,000 intersections across the [US].

Now I just need to know how many signaled intersections there are across the [US].

Also, wouldn't it be cool to have a system to let emergency vehicles make stop signs explode?

Wait, those prices are for aftermarket or pirate devices. Still, how much can an overpowered TV remote cost?

According to Google Translate, that is Esperanto:

Traffic lights, which I feel is very important, such transport vehicles will be a very good order, and not a lot of accidents.
