Gary Lauder's new traffic sign: Take Turns

Prevodilac: Ivana Korom Lektor: Sandra Gojic

I only have three minutes

Imam samo tri minuta

so I'm going to have to talk fast, and it will

pa moram brzo da pričam i to će

use up your spare mental cycles, so multitasking may be hard.

opteretiti vaš mozak - multitasking može biti naporan.

So, 27 years ago I got a traffic ticket

Dakle, pre 27 godina dobio sam saobraćajnu kaznu

that got me thinking.

zbog koje sam se zamislio.

I've had some time to think it over.

Imao sam neko vreme da promislim o tome.

And energy efficiency is more than just

Kod uštede energije ne radi se

about the vehicle --

samo o vozilu.

it's also about the road.

Radi se i o putu.

Road design makes a difference, particularly intersections,

Izgled puta ima uticaja, naročito raskrsnice,

of which there are two types: signalized

kojih postoji dve vrste: sa signalizacijom

and unsignalized, which means stop signs.

i bez, što znači sa stop znacima.

Fifty percent of crashes happen at intersections.

Pola sudara desi se na raskrsnicama.

Roundabouts are much better.

Kružni tokovi su mnogo bolji.

A study of 24 intersections

Studija o 24 raskrsnice

has found crashes drop 40 percent

pokazala je da se sudari smanje za 40%

from when you convert a traffic light into a roundabout.

kada se raskrsnica sa semaforom pretvori u kružni tok.

Injury crashes have dropped 76 percent,

Sudari sa povredama smanjili su se za 76%.

fatal crashes down 90 percent.

Smrtne nesreće smanjile su se za 90%.

But that's just safety.

Ali to je samo bezbednost.

What about time and gas?

Šta je sa vremenom i gorivom?

So, traffic keeps flowing, so that means less braking,

Znači, saobraćaj teče, to znači manje kočenja,

which means less accelerating, less gas and less pollution,

što znači manje ubrzavanja, manje goriva i manje zagađenja,

less time wasted,

manje protraćenog vremena,

and that partly accounts for Europe's better efficiency

a time se objašnjava bolja efikasnost u Evropi,

than we have in the United States.

nego što je kod nas u Sjedinjenim Državama.

So, unsignalized intersections,

Dakle, raskrsnice bez signalizacije,

meaning stop signs, they save many lives,

one sa stop znacima, spašavaju mnoge živote,

but there's an excessive proliferation of them.

ali je došlo do njihovog prekomernog širenja.

Small roundabouts are starting to appear.

Pojavljuju se mali kružni tokovi.

This is one in my neighborhood. And they are

Ovo je jedna u mom kraju. One su

much better -- better than traffic lights, better than four-way stop signs.

mnogo bolje - bolje od semafora, bolje od stop znakova.

They're expensive to install,

Skupe su za izgradnju,

but they are more expensive not to. So, we should look at that.

ali još je skuplje ne graditi ih. Trebalo bi tako da gledamo.

But they are not applicable in all situations.

Ali nisu primenjive u svim situacijama.

So, take, for example, the three-way intersection.

Uzmite, na primer, ukrštanje 3 puta.

So, it's logical that you'd have one there,

Logično je da će biti jedna tamo,

on the minor road entering the major.

gde se manji put ukršta sa većim.

But the other two are somewhat questionable.

Ali druge dve su prilično diskutabilne.

So, here's one. There's another one which I studied.

Evo jedne. Evo još jedne koju sam proučavao.

Cars rarely appear on that third road.

Kola se retko pojavljuju na tom trećem putu.

And so, the question is, what does that cost us?

Pitanje je, koliko nas to košta?

That intersection I looked at had about 3,000

Raskrsnicom koju sam ja posmatrao prođe oko 3000

cars per day in each direction,

automobila dnevno u oba pravca,

and so that's two ounces of gas to accelerate out of.

i to je oko 60ml goriva da se prođe kroz nju.

That's five cents each, and times 3,000 cars per day,

To je 5 centi po kolima, puta 3000 kola dnevno

that's $51,000 per year.

to je 51.000$ godišnje.

That's just the gasoline cost. There is also pollution,

To je samo za benzin. A tu je još i zagađenje,

wear on the car, and time.

trošenje automobila i vreme.

What's that time worth?

Koliko je vredno to vreme?

Well, at 10 seconds per 3,000 cars,

Pa, 10 sekundi puta 3000 automobila,

that's 8.3 hours per day. The average wage in the U.S.

to je 8.3h dnevno. Prosećna cena sata u Americi

is $20 an hour. That is 60,000 per year.

je 20$. To je 60.000$ godišnje.

Add that together with the gas, and it's $112,000 per year,

Zajedno sa gorivom, to je 112.000$ godišnje

just for that sign in each direction.

samo za taj znak u oba pravca.

Discount that back to the present, at five percent:

Izračunajte to danas, sa 5%:

over two million dollars

preko dva miliona dolara

for a stop sign, in each direction.

za stop znak, u oba pravca.

Now, if you look at what that adjacent property is worth,

Ako pogledate koliko je vredno to susedno imanje,

you could actually buy the property,

mogli biste da kupite to imanje,

cut down the shrubbery to improve the sight line,

posečete žbunje da popravite preglednost

and then sell it off again.

i onda ga opet prodate.

And you'd still come out ahead.

I opet biste bili na dobitku.

So, it makes one wonder, "Why is it there?"

Tako se zapitate, "Zašto to postoji?"

I mean, why is there that stop sign in each direction?

Mislim, zašto postoji stop znak u oba pravca?

Because it is saving lives. So, is there a better way to accomplish that goal?

Zato što spašava živote. Postoji li bolji način da se to postigne?

The answer is to enable cars

Odgovor je da omogućimo automobilima

to come in from that side road safely.

da bezbedno priđu sa tog sporednog puta.

Because there are a lot of people who might live up there

Mnogo ljudi možda živi tamo

and if they're waiting forever a long queue could form

i ako čekaju doveka, može se napraviti dug red

because the cars aren't slowing down on the main road.

jer automobili ne usporavaju na glavnom putu.

Can that be accomplished with existing signs?

Može li se to postići postojećim znacima?

So, there is a long history of stop signs and yield signs.

Duga je istorija stop znakova i trouglova.

Stop signs were invented in 1915,

Stop znak izmišljen je 1915.

yield signs in 1950. But that's all we got.

Trougao 1950. Ali to je sve što imamo.

So, why not use a yield sign?

Zašto ne bismo onda koristili trougao?

Well the meaning of yield is: You must yield the right-of-way.

Jer značenje trougla je: nailazite na put sa pravom prvenstva.

That means that if there are five cars waiting, you have to wait

To znači da ako petoro kola čeka, morate sa sačekate

till they all go, then you go. It lacks the notion

dok svi oni prođu, onda krećete. Nedostaje ideja

of alternating, or taking turns,

smenjivanja ili naizmeničnog kretanja.

and it's always on the minor road,

I uvek je na manjem putu,

allowing the major one to have primacy.

dajući većem pravo prvenstva.

So, it's hard to create a new meaning for the existing sign.

Znači, teško je stvoriti novo značenje za postojeći znak.

You couldn't suddenly tell everyone, "OK, remember

Ne možete odjednom reći svima, "Ok, sećate se

what you used to do at yield signs? Now do something different."

šta znači trougao? Sad uradite nešto drugo."

That would not work.

To ne bi išlo.

So, what the world needs now

Ono što je svetu potrebno sada

is a new type of sign.

je nova vrsta znaka.

(Applause)

(aplauz)

So, you'd have a little instruction below it,

Imali biste malo uputstvo ispod,

you know, for those who didn't see the public service announcements.

znate, za one koji nisu videli javno obaveštenje.

And it merges the stop sign and yield signs.

Ovaj znak objedinjuje stop i trougao.

It's kind of shaped like a T, as in taking turns.

Oblikovan je kao slovo T (taking turns - smenjivanje).

And uncertainty results in caution.

A nesigurnost za posledicu ima obazrivost.

When people come to an unfamiliar situation they don't know how to deal with

Kada se ljudi nađu u nepoznatoj situaciji u kojoj ne znaju šta da rade,

they slow down.

oni uspore.

So, now that you are all "Road Scholars" ...

Sada pošto ste svi saobraćajno obrazovani...

(Laughter)

(smeh)

don't wait for that sign to be adopted, these things don't change quickly.

nemojte čekati da se taj znak usvoji, ove stvari se ne menjaju brzo.

But you all are members of communities,

Ali svi ste članovi zajednica

and you can exercise your community influence

i možete vežbati svoj uticaj u zajednici

to create more sensible traffic flows.

kako biste stvorili razumnije tokove saobraćaja.

And you can have more impact on the environment

I možete imati veći uticaj na okolinu

just getting your neighborhood to change these things

samo menjanjem ovih stvari u svom kraju,

than by changing your vehicle. Thank you very much.

nego menjanjem vozila. Hvala vam mnogo.

(Applause)
