What about time and gas?

ืžื” ืขื ื–ืžืŸ ื•ื“ืœืง?
01:02
So, traffic keeps flowing, so that means less braking,

ืื–, ื”ืชื ื•ืขื” ืžืžืฉื™ื›ื” ืœื–ืจื•ื, ืžื” ืฉืื•ืžืจ ืคื—ื•ืช ื‘ืœื™ืžื•ืช,

ืžืืฉืจ ื–ื• ื‘ืืจืฆื•ืช ื”ื‘ืจื™ืช.
01:13
So, unsignalized intersections,

2000
ืื–, ืฆืžืชื™ื ืœื ืžืจื•ืžื–ืจื™ื,
01:15
meaning stop signs, they save many lives,

Small roundabouts are starting to appear.

This is one in my neighborhood. And they are

ื–ื• ืื—ืช ื‘ืฉื›ื•ื ื” ืฉืœื™. ื•ื”ืŸ

much better -- better than traffic lights, better than four-way stop signs.
31

3000
ื˜ื•ื‘ื•ืช ื‘ื”ืจื‘ื” ืžืจืžื–ื•ืจื™ื, ื•ืžืชืžืจื•ืจื™ ืขืฆื•ืจ ื‘ื›ืœ ื”ื›ื™ื•ื•ื ื™ื.
01:28
They're expensive to install,
32
88260
2000
ื”ืŸ ื™ืงืจื•ืช ืœื”ืชืงื ื”,
01:30
but they are more expensive not to. So, we should look at that.
33

3000
ืื‘ืœ ื™ืงืจ ื™ื•ืชืจ ืœื ืœื”ืชืงื™ืŸ ืื•ืชืŸ. ืื– ืฆืจื™ืš ืœื‘ื—ื•ืŸ ืืช ื–ื”.
01:33
But they are not applicable in all situations.

1000
ืื‘ืœ ื”ืŸ ืœื ืžืชืื™ืžื•ืช ืœื›ืœ ื”ืžืฆื‘ื™ื.
01:34
So, take, for example, the three-way intersection.
35
94260
3000
ืื–, ืงื—ื• ืœื“ื•ื’ืžื”, ืฆื•ืžืช ื˜ื™.
01:37
So, it's logical that you'd have one there,
36

2000
ืื– ื”ื’ื™ื•ื ื™ ืฉื™ื”ื™ื” ืขืฆื•ืจ ืื—ื“ ืฉื,
01:39
on the minor road entering the major.

ืขืœ ื”ื›ื‘ื™ืฉ ื”ืฆื“ื“ื™ ืฉื ื›ื ืก ืœืจืืฉื™.
01:41
But the other two are somewhat questionable.

3000
ืื‘ืœ ื”ืฉื ื™ื™ื ื”ืื—ืจื™ื ื ืชื•ื ื™ื ืœื•ื•ื™ื›ื•ื—.
01:44
So, here's one. There's another one which I studied.

ืื– ื”ื ื” ืื—ื“. ื–ื” ืขื•ื“ ืื—ื“ ืฉื—ืงืจืชื™.
01:46
Cars rarely appear on that third road.

ืžื›ื•ื ื™ื•ืช ืžื•ืคื™ืขื•ืช ืœืขื™ืชื™ื ืจื—ื•ืงื•ืช ื‘ื›ื‘ื™ืฉ ื”ืฉืœื™ืฉื™.
01:49
And so, the question is, what does that cost us?
41
109260
2000
ื•ืื–, ื”ืฉืืœื” ื”ื™ื, ื›ืžื” ื–ื” ืขื•ืœื” ืœื ื•?
01:51
That intersection I looked at had about 3,000

2000
ืžื›ื•ื ื™ื•ืช ื‘ื™ื•ื ื‘ื›ืœ ื›ื™ื•ื•ืŸ,
01:55
and so that's two ounces of gas to accelerate out of.
44

2000
ืื– ื–ื” ื›ืžื” ื’ืจืžื™ื ืฉืœ ื“ืœืง ืœื”ืื™ืฅ ืžืฉื.
01:57
That's five cents each, and times 3,000 cars per day,
45

2000
ื–ื” 5 ืกื ื˜ ืœื›ืœ ืื—ืช, ื•ื›ืคื•ืœ 3000 ืžื›ื•ื ื™ื•ืช ื‘ื™ื•ื,
01:59
that's $51,000 per year.
46
119260
3000
ื–ื” 51000 ื“ื•ืœืจ ื‘ืฉื ื”.
02:02
That's just the gasoline cost. There is also pollution,
47
122260
2000
ื–ื” ืจืง ืขืœื•ืช ื”ื“ืœืง. ื™ืฉ ื’ื ืืช ื”ื–ื™ื”ื•ื,

wear on the car, and time.
48

2000
ื‘ืœืื™ ืฉืœ ื”ืžื›ื•ื ื™ืช, ื•ื–ืžืŸ.
02:06
What's that time worth?
49
126260
2000
ื›ืžื” ื”ื–ืžืŸ ื”ื–ื” ืฉื•ื•ื”?
02:08
Well, at 10 seconds per 3,000 cars,

128260
2000
ืื–, ื‘10 ืฉื ื™ื•ืช ืœ3000 ืžื›ื•ื ื™ื•ืช,
02:10
that's 8.3 hours per day. The average wage in the U.S.

4000
ื”ื™ื 20$ ืœืฉืขื”. ื–ื” 60000 ื‘ืฉื ื”.
02:16
Add that together with the gas, and it's $112,000 per year,

ืชื•ืกื™ืคื• ืืช ื–ื” ืœื“ืœืง, ื•ื–ื” 112000 ืœืฉื ื”

ืจืง ืœืฉืœื˜ ื‘ื›ืœ ื›ื™ื•ื•ืŸ.
02:21
Discount that back to the present, at five percent:

ืœืชืžืจื•ืจ ืขืฆื•ืจ, ื‘ื›ืœ ื›ื™ื•ื•ืŸ.
02:29
Now, if you look at what that adjacent property is worth,
58

ืขื›ืฉื™ื•, ืื ืชื‘ื“ืงื• ื›ืžื” ื”ื ื›ืก ื”ืงืจื•ื‘ ืฉื•ื•ื”,

you could actually buy the property,

ื”ื™ื™ืชื ื™ื›ื•ืœื™ื ืœืงื ื•ืช ืืช ื”ื ื›ืก,

2000
ื•ืื– ืœืžื›ื•ืจ ืื•ืชื• ืฉื•ื‘.

And you'd still come out ahead.

ื•ืขื“ื™ื™ืŸ ื”ื™ื™ืชื ื ืฉืืจื™ื ืขื ืขื•ื“ืฃ.
02:42
So, it makes one wonder, "Why is it there?"
63
162260
2000
ืื– ื–ื” ื’ื•ืจื ืœื™ ืœื—ืฉื•ื‘, "ืœืžื” ื”ื•ื ืฉื?"

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

02:47
Because it is saving lives. So, is there a better way to accomplish that goal?
65
167260
3000
ืžืคื ื™ ืฉื”ื•ื ืžืฆื™ืœ ื—ื™ื™ื. ืื– ื”ืื ื™ืฉ ื“ืจืš ื˜ื•ื‘ื” ื™ื•ืชืจ ืœื”ืฉื™ื’ ืืช ื”ืžื˜ืจื”?
02:50
The answer is to enable cars

2000
ื”ืชืฉื•ื‘ื” ื”ื™ื ืœืืคืฉืจ ืœืžื›ื•ื ื™ื•ืช

2000
ืœื”ื’ื™ืข ืžื”ืฆื“ ื”ื”ื•ื ื‘ื‘ื˜ื—ื”.
02:54
Because there are a lot of people who might live up there

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

ื•ืื ื”ื ืžื—ื›ื™ื ื”ืžื•ืŸ ื–ืžืŸ ืชื•ืจ ืืจื•ืš ื™ื›ื•ื— ืœื”ื•ื•ืฆืจ

Can that be accomplished with existing signs?

03:03
So, there is a long history of stop signs and yield signs.

03:13
Well the meaning of yield is: You must yield the right-of-way.
