  • yeah

  • welcome to the series that takes you to the heart of america and reveal the

  • inner workings of our country as you have never seen them before

  • I'm you'll quan I've worked in many different fields from law to government

  • to business

  • I've even one the reality show survivor but in every part of my life I've been

  • fascinated by the same things systems and networks we're going to go on quite

  • a journey coast-to-coast across this sprawling land to discover the habits

  • the rhythms and the secrets that you only notice when you step back and see

  • the big picture interchanges oddly elegant in the next hour

  • aerial photography and satellite tracking will reveal how America's

  • transportation systems make us the most mobile people on earth

  • we built the vast networks of roads rails and airwaves and an army of

  • workers keep the wheels turning

  • hey let's like the bus driver but it's getting harder and harder to keep all

  • these systems running well i think the freeways will get so slow where a lot of

  • people just decide it's not worth the grief many of them are aging designed at

  • a time when America was far less crowded you have a disruption at one place and

  • it ripples all the way across country it does have a ripple effect but even as he

  • struggled to keep up every day our systems miraculously managed to get us

  • where we need to go

  • this is a story of 310 million Americans on the move

  • this is America revealed

  • yeah

  • America revealed is made possible by the Corporation for Public Broadcasting

  • and by contributions to your PBS station from viewers like you

  • thank you

  • monday morning just before dawn

  • but this isn't the night sky

  • this is America this is us

  • each of these points of light represents 7,500 people they create brilliant

  • constellations that span the continent from the faint glow of small towns to

  • the blaze of cities like Chicago and New York to connect these dots we built four

  • million miles of roads 200,000 miles of rails 5,000 airports the largest

  • transportation network in history

  • but keeping it all moving that's America's challenge in the 21st century

  • and nowhere does that challenge loom larger than in New York City it's the

  • perfect example of a powerful but aging transportation network that moves

  • millions even while straining under their weight take the island of

  • Manhattan 23 square miles home to 1.6 million people every weekday morning is

  • population nearly doubles swelling with an army of commuters these people are

  • essential to the life of the city getting all of them onto this tiny

  • island in only a few hours is a daily adventure that teeters on the edge of

  • chaos and it's about to begin at 630am I'm coming in on the red-eye from LA to

  • JFK International Airport and I've got plenty of company reported the path of

  • every plane landing in New York's three major airports in a 24-hour period a

  • flight comes and goes every 24 seconds that's more than 3,500 flights a day

  • I 7am thousands of yellow cabs are picking up their first fears of the day

  • at the airports and heading for men hand this taxi is one in 50,000 vehicles that

  • will leave its way through New York's necklace of bridges and tunnels in the

  • next power just below these bridges more than a hundred thousand people are

  • traveling to and from the island by boat

  • these are the traces of those vessels darting around New York's rivers and

  • harbor including one fleet which alone Carrie 65,000 commuters a day

  • staten island ferry

  • yeah

  • as thousands descend on the island by here road and water even more arrive by

  • rail

  • long island railroad trains carry suburban commuters into Manhattan every

  • two to four minutes along with pack trains from New Jersey and amtrak trains

  • they all converge at America's busiest commuter hub New York's penn station

  • while only a few blocks away

  • trains from the north stream into another bustling train station grand

  • central terminal

  • but getting people on to Manhattan is just half the battle

  • now they have to deal with this

  • the streets run yellow with taxis competing with thousands of trucks and

  • cars and bus routes crisscross the island adding another layer to the

  • traffic

  • I'm not surprised the word gridlock originated here

  • it's ATM and it looks like nobody's going anywhere

  • but beneath the streets it's a different story

  • i'm talking about the subway every day this system carries over 5 million

  • passengers citywide without it

  • traffic would overwhelm Manhattan streets and the city couldn't function

  • but the subway has had an even bigger impact than that starting in the early

  • nineteen hundreds when the first track was laid to build a transportation

  • system in America whole cities and towns will spring up around it the subway

  • system is a prime example it determined how New York City took shape and dictate

  • the patterns of its inhabitants lives look beneath this forest of midtown

  • Manhattan skyscrapers multiple subway lines converge here funneling in

  • hard-working commuters from the city's outer boroughs like Queens

  • this is a snapshot of what Queens look like in 1917 when subway construction

  • was just getting started and here is what it looks like today a busy vibrant

  • borough the subway made Queens possible

  • but how

  • 100 years ago to combat overcrowding and lower Manhattan tenements New York

  • expanded its fledgling subway system to the sparsely populated outer boroughs

  • critics call them the tracks to nowhere but New Yorkers soon got onboard lured

  • by the promise of open land just a short ride from their jobs

  • by the nineteen-twenties these lines were carrying more passengers than they

  • could handle the city plan to add over 100 miles of new track but first the

  • Depression hit then World War two

  • yeah

  • today we're stuck with the same basic wheels that were out of date in the

  • nineteen thirties and the number of passengers keeps going up with every

  • passing decade it's a pattern will see all over the country enormous but aging

  • system was working hard harder to keep up with the growth to help create it's

  • ten a.m. in the morning commute is winding down the city has survived

  • another rush hour and millions have made it to their destinations New York's

  • public transit system may be old and crowded but without it this teeming

  • metropolis would come to a screeching halt the same is true across the country

  • are public transportation systems are what keep the nation moving there's one

  • system that carries a whopping 26 million Americans every day more than

  • any other form of public transport

  • there it is

  • there it is again the humble school bus

  • what's up guys good morning and come to kingman arizona to meet a guy who keeps

  • one of these yellow Marvel's moving here

  • rush hour is just beginning for many students in this desert community buses

  • are the only way to get to school around the country kids rely on a half-million

  • member army of transportation experts the nations school bus drivers here

  • let's make the bus driver when these kids are on the bus

  • they're my kids and I'll mess and I don't take that lightly

  • you have to be the mother the father the mediator the nurse the cool uncle

  • like how many miles you drive every day on average all do about a hundred

  • sixty-five miles a day and that's a few that's just me

  • this is mike's bus it's just one of kingdoms 53 buses replanted gps devices

  • on them and found that they drive one-and-a-half million miles every year

  • to every corner of the school district an area the size of Delaware that's

  • repeated nationwide in thousands of school districts large and small tho

  • system quite like this anywhere in the world here in the US

  • if you can't get there on foot you can get a ride to your local school even if

  • it's not that local so you guys are really kind of like the lifeblood of the

  • system right i mean without you these kids wouldn't even be able to get an

  • education

  • no they wouldn't be able to get the school now we keep pumping the kids in

  • so they can get educated

  • our school buses worked amazingly well which is good considering how much we

  • rely on them but there are other transportation networks out there that

  • face big challenges including the system that first connected the country from

  • coast to coast and made modern America possible

  • the railroads

  • to create a nation wide web of tracks the federal government launched one of

  • the most ambitious and expensive infrastructure projects in human history

  • and for nearly a hundred year's America's railways were the fastest and

  • most popular way to travel but not anymore to get a glimpse of what keeps

  • our trains going and what slows them down

  • I've come to the rail hub of the United States Chicago

  • more trains pass through this city than any other because in the eighteen

  • hundreds Chicago's politicians lobby to make sure all national rail lines and

  • here

  • that created jobs but also logistical nightmares

  • today there are three different systems here with different needs all fighting

  • for space on one set of tracks commuter trains making local pickups amtrak

  • trains traveling longer distances with fewer stops but those two passenger

  • networks are dominated by the biggest slowest network of all

  • yeah

  • free

  • our economy depends on goods carried by rail from coast to coast

  • we have the world's most efficient and profitable trade system moving nearly

  • ten times as much as $MONEY euro

  • it's so successful that free companies owned most of America's tracks and many

  • of our freight trains pass through one small section of Chicago's freight yards

  • 27 miles of track behind me will move about 1.75 million free cars each year

  • but this phenomenal success has come at a price

  • the system isn't nearly as good at moving something else people so what is

  • it about the freight system that gets in our way

  • this is Jack strength is using a remote control to push that train of a man-made

  • he'll be call the double hump shipping companies built this hill so that men

  • like Jack can process all the free coming through this yard and reassemble

  • cars according to destination the network we depend on to ship our goods

  • depends on Jack his remote control and a surprisingly simple process known as

  • pumping pumping is exactly a slang word for classifying the cars sorting kind of

  • like a postal facility but instead of sorting mail your starting these kinds

  • of time freight cars exactly after Jack pushes the cars up the hill area called

  • she separates them by hand a century old technique called pin pulling this bar up

  • her give me a signal so they want to make the cut

  • and then jackets gravity drag each car down the other side of the hump to its

  • outbound track

  • these cars carry chemicals bound for Virginia lumber on the way to michigan

  • sugar for a cookie factory in st. Louis and they all have to wait their turn in

  • line at the double hump everything that moves through America loose through

  • these yards exactly a lot of times you can tell how the economy is running out

  • here just by what's coming into the yard itself

  • all across the country people and free have to share the same tracks seeing

  • these mile long slow moving freight trains heading out of Chicago to the

  • long-distance rail network i can understand why passenger travel suffers

  • 2010 the federal government pledged $MONEY billion dollars towards a

  • potential solution the construction of new and upgraded tracks for speedier

  • passenger rail system but that's only fifteen percent of the plans 53 billion

  • dollar price tag

  • even if all that funding comes through most long-distance travelers will

  • probably still choose a different way to get from here to there one that's newer

  • and much faster

  • 17

  • this is the scene at houston's george bush intercontinental airport air travel

  • more than any other mode of modern transportation has bridged our continent

  • and sped up our lives and every year more and more of us are taking to the

  • skies

  • this is flight data for the 50,000 planes i will carry almost 2 million

  • passengers today

  • it shows how r airways connect every corner of the country from sleepy rural

  • area strips to major hubs like chicago's o'hare international airport where on

  • this day a plane is taking off or landing every 34 seconds that's nearly a

  • million flights each year

  • the fast system has created a completely new way of life people flowing through

  • these airports are just occasional passengers there are new breed of road

  • warrior who often fly thousands of miles every week one of those very frequent

  • flyers is international insurance salesman deanery i'm doing final no I

  • never checked bags

  • morning how are you thank you

  • a typical trip in miami tampa tampa Houston Houston vegas vegas to houston

  • houston the Dallas of dallas to tokyo tokyo to hong kong macau as possible

  • account shanghai shanghai at tokyo tokyo to LA to dallas dallas the Tampa that

  • was 11 days

  • Dean spend a lot of time in the air so we can maintain face-to-face contact

  • with his clients around the world

  • what are some of the inside secrets of the trade that people like you know that

  • other people don't

  • oh gosh I mean there's so many of them it's on every subject you know how you

  • pack is a key one you know how you go through the security line it's all about

  • logistics for the most part all the tricks and what do you do when something

  • goes wrong you want to you anticipate it started to snow i've looked at

  • weather.com or whatever so you start making backup reservations sometimes

  • I'll have two or three reservations at a time have to be offensive vs defensive

  • that's the secret of a real Road Warrior

  • it's not just road warriors like Dean zigzagging through our skies air travel

  • is so common today that our Airways are filled with all kinds of travelers some

  • of them more unusual than others

  • here are three regular passenger flights one passenger on each flight is

  • traveling in cargo brought aboard in a special box called an air trade baggage

  • compartments of commercial airlines are the most common way to ship dead bodies

  • long distances everyday 50 are shipped from one state alone

  • florida it's a retirement Mecca but when those golden years come to an end many

  • deceased retirees are flown home for burial these passengers on the other

  • hand are very much alive but they're under armed guard and they wear

  • handcuffs as well as seatbelts

  • they're traveling courtesy of the Justice Department which runs its own

  • airline flying prisoners too distant court hearings or Penitentiary's and

  • reporting some illegal aliens out of the country with so many people flying for

  • one reason or another our skies are the busiest in the world but they weren't

  • always so crowded

  • i'm heading to mcdonald past Montana to visit a relic of our earliest days of

  • flight

  • transportation wise this place is definitely off the grid

  • not fun feel like I'm standing on top of the world pretty much are we on top

  • continental divide the call montana big sky country and it does look pretty

  • empty up here but this 90-foot tower holds a clue to how we learn to navigate

  • are crowded skies microorganism with the Montana Department of Transportation

  • aeronautics division so I wouldn't be things that basically do the give you a

  • visual reference when you're flying at night so these literally are kind of

  • like lighthouses in the sky

  • yes the story of this air beacon dates back to the birth of commercial air

  • travel in the nineteen-twenties aviation companies were eager to fly

  • cross-country but they had no way to navigate the night portion of the 30

  • hour trip

  • so they invented one paying farmers to light bonfires in their fields creating

  • a path of flames to guide pilots through the night

  • soon replaced the bonfires with a network of 1500 gasps beacons coming in

  • nicely 25 me way Ben

  • by the 1960s modern radar was replacing the gas beacons except in Montana where

  • the peaks of the Rockies block radar signals leaving pilots to rely on the

  • old beacons so they wouldn't crash into the mountains to this day my continues

  • to tend the beacons and make sure they're in good working order the heck

  • of a client

  • it's a long one isn't so this is what the pilots actually see this lamp is

  • focused in the middle of this 24 inch mirror and as it's turning around you

  • get sharp flashes you're you're approaching the beacon when you see the

  • beacon it looks like it's flashing that's because it's turning around you

  • only get them for a second

  • even though every other state has long since abandoned the beacons we still

  • live with their legacy many of the first radar towers were built along this

  • network of gas beacons which means that if you take a commercial flight today

  • and fly along one of the early skyways your path will look like a zigzag that

  • traces the lines that sprang up from bonfire to bonfire and then become a

  • beacon from bonfire to beacon to radar we've made progress

  • but as our skies got busier we needed a way to handle the traffic

  • enter the federal aviation administration faa which maintains our

  • complex flight management system today

  • here's how it works

  • each airport control tower guides each plane to take off then a regional

  • control center keeps tabs on it until it reaches 10,000 feet where the flight

  • enters one of the 21 enroute centers across the country and watching over the

  • entire system are the people in this state-of-the-art bunker in Northern

  • Virginia people like flight manager Debra Griffith air traffic control

  • system commands and places of minutes

  • ya feel like a minute movie wargames or something

  • now what are all those lights up on that screen those are flights those would be

  • active lights in the system right now how many planes we look at during the

  • peak portion of the day were five to six thousand flights active it's Tuesday

  • afternoon just an ordinary day for Deborah was sort of a traffic cop of the

  • skies

  • morning everybody this is the perfect with you for the 1215 planning telecon

  • we're going to start with New York having the gusty winds morning York

  • morning thank you we are on a 33 love every two hours

  • Deborah Leeds what could be the biggest conference call in the world thousands

  • of passengers lives are on the line about west to Southern California track

  • on you consider any more information right now just don't get it with the rbr

  • the world feeling this every major airline airport shipping company the

  • Secret Service NASA and the military listening for updates to the national

  • flight plan to terminal history of our ceilings in this

  • ok that will conclude this cell phone will be back with you at fourteen

  • fifteen command centers out thank you as soon as she hangs up Deborah begins

  • juggling this networks limited air space to keep traffic flowing down San

  • Francisco Board can actually put ceilings in there for hours this morning

  • alright she reroutes planes around san francisco's fog and ground others so

  • they won't get caught in a bottleneck caused by strong winds over New York

  • right now going down to the next four hours see how their rules

  • so it's kinda like a butterfly effect where you have a destruction in one

  • place in it ripples all the way across country

  • it does have a ripple effect it does because New York is slow down its gonna

  • historically slow down the other markets around it because those those airplanes

  • go in and out of New York and go to Fort Worth and to houston and remember

  • sentence kogda Cleveland all these flights depend on Deborah's ability to

  • manage America's airspace

  • she's good at it and the system works well most of the time but the problem

  • with this system is that it's based on radar aging technology that requires air

  • traffic controllers to leave large safety margins between each plane which

  • means fewer planes can take to the sky with our Airways nearing maximum

  • capacity

  • the FAA needs a game changer

  • if the air becomes a montana recall Aviation's past you can get a taste of

  • our future by heading to an even more isolated part of the country this is

  • rush are in Juneau Alaska only ten percent of this state is accessible by

  • Road show up here every day commuting depends on pilots like Sam right

  • wow this totally beats my own computer

  • welcome to my office

  • it may be beautiful but over the past 20 years

  • one-third of all commuter plane crashes in the United States happened in Alaska

  • and sand flies these treacherous skies everyday and what exactly is your job my

  • job is to pick people and great male UPS FedEx from juno which is the Jetport to

  • all the smaller communities around Southeast Alaska what are some of the

  • more common and uncommon things that you transported well very very very very

  • pregnant women taking the hospital for delivery i'm taking a piss you off

  • because everyone that's a serious thing to me

  • knock on wood I've made it every time wolves we carry pools and carry affairs

  • carried a really pissed-off Wolverine is winter the Wolverine was going to finish

  • soda or someplace to be bred and he didn't know that so he was spot-on

  • so you really are sort of like the connective tissue that allows these

  • outlying communities to interact on a daily basis with rest of the world

  • that's true we look at ourselves more like a little air road system how hard

  • is it to fly around here is it is a challenging

  • well today's like a gorgeous day right you can see 480 miles hundred miles

  • after some days we can only see two miles in Alaska as a montana rows of

  • mountains block radar signals and the snow and fog can quickly roll in from

  • the ocean forcing pilots to fly blind among the glaciers

  • so pilots like Sam are using a new satellite-based gps system which unlike

  • radar can reach every corner of their airspace so basically this shows you

  • everything that's in your immediate vicinity right absolutely

  • if you make a turn toward something higher than you that will turn red

  • it will say hey this is red this is not a good idea in Alaska the accident rate

  • for planes that have been equipped with GPS has dropped by almost fifty percent

  • and this system that keeps Salmons passengers safe is beginning to have a

  • much wider impact gps is a backbone of a new FAA plan called next-gen designed to

  • completely overhaul air traffic control air alaska was one of the first airlines

  • to test this new technology their pilots like Mike Adams welcome to one of the

  • most advantageous features about the next-gen program ability now to navigate

  • or directly these blue symbols represent ground-based navigation aids that prior

  • times we would have been flying a zigzag line between those as we go from station

  • to station now with GPS navigation we can fly directly from way . away . as

  • you see here and that allows us to shorten our route distance create a more

  • direct flight and that in turn freeze-up air space for other craft occupy hence

  • increasing capacity the estimated cost for next-gen as high as much as a

  • hundred and sixty billion dollars but it will allow the FAA dy 1.3 billion

  • passengers a year by 2031 twice as many as I can handle today

  • so far I've been traveling mostly on planes and trains all packed full of

  • people the most Americans prefer their personal space so getting from A to B

  • usually means one thing

  • cars that's definitely true in dallas here like most of the country Americans

  • take driving for granted

  • return the key and go while driving feel of like individual choice it's only

  • possible because of our system of highways which is one of the busiest and

  • most sophisticated pieces of infrastructure in the world and we have

  • grown so dependent on the freedom and mobility of the open road collectively

  • driving three trillion miles every year at today the health of our country

  • depends on the health of our highways

  • so specialists like traffic analyst Greg Jordan work behind the scenes to help

  • improve the flow of traffic

  • like that beauty

  • interchanges oddly elegant know it's kind of like some sort of geometric

  • shapes an aerial perspective will give you an insight that is sometimes very

  • hard to get on the ground

  • he's right from the sky

  • I can see where cars are bottlenecking and where they're moving along at a nice

  • clip local transportation planners from New York to California value Greg's

  • expertise

  • he provides data so they can see for themselves where they need to invest in

  • roads where they need to build new ones or widen them or increase Highway Patrol

  • and are you actually getting that data

  • well it's it's mainly time-lapse photography looking at the snapshots

  • greg has taken over time which strikes me is not just the roads themselves but

  • the number of housing developments hugging the highways this is a new

  • development if this is in Louisville it's right near the newly completed

  • state highway 121 so these communities are only possible because of that

  • freeway the freeway is the lifeblood people like to say if you build it they

  • will come and into a degree that's true of coming out with you build it that

  • encourages people

  • this is what more and more of our country looks like today a tapestry of

  • suburban neighborhoods woven together by quiet streets and bordered by dizzy

  • highways when the federal government started building these interstate

  • highways more than 50 years ago they were intended to strengthen connections

  • between far-flung cities but they ended up totally reshaping local communities

  • this is what the sleepy town of arlington texas look like in 1950 and

  • this is what happens when interstate 30 connected to nearby dallas and fort work

  • highway stretching north from Dallas Lord people out to the cheap land and

  • open space of Arlington and other suburbs like this one colleague

  • and these suburbs gave birth to a whole new meaning of life

  • this is a suburban dream the cul-de-sac big houses surrounded by green logs on a

  • street with no through traffic but living here comes at a cost to

  • understand that cost we used GPS to track the cars of everyone living on

  • this tiny cul-de-sac for a week

  • each color represents one of the five families that pink car is phil thompson

  • heading to work their Savior ue driving her son's to school her husband Kip in

  • the red car is on his way to the airport for a business trip

  • our car culture is so common now that we forget how different it is from the

  • rhythms of urban american life just a half-century ago modern suburbs promote

  • a landscape where most things are accessible only by car so the suburban

  • residents spend much of their time behind the wheel

  • they drive to get coffee thank you to do their banking buy groceries in fact the

  • dr fifty percent more than their parents did I probably put on maybe a hundred

  • miles a day easily 25,000 30,000 miles a year but basically the assumption is

  • that if you're gonna live in this neighborhood

  • you have to have a car that's exactly right the way they design colleyville

  • and in our community is this it's off the beaten path you have to drive 10 or

  • 15 minutes before you get to a major road and all this driving means our

  • families walk a whole lot less walking is definitely more recreational I walk

  • the dogs in the neighborhood to the mailbox and back now the other walking i

  • do is going to be from parking garages to appointments when I go to customer

  • meetings between the rental car agency and and the gates of the airport's most

  • of us don't mind all this driving but there's a problem as suburban life

  • evolves and our daily destinations change our road system can't adapt fast

  • enough

  • look at our five families they rarely venture into the city of dallas all week

  • our highways were designed to get people from the suburbs two jobs and stores in

  • the central business districts but nowadays most people live work and shop

  • in the suburbs and the smaller secondary roads are jammed on top of that since we

  • built our highway system the population has doubled and the number of cars on

  • the road has more than tripled that means more people stuck in traffic on

  • roads that weren't designed to get them where they want to go at the end of the

  • week after collectively navigating over 600 miles of suburban thoroughfares our

  • family's return to the cul-de-sac there are the Johnsons last ones in

  • yeah

  • meanwhile few miles away road construction crews are just beginning

  • the workday the dallas-fort Worth area planners are trying to reduce congestion

  • by building the way out in the problem

  • this place is home to more road construction than anywhere else in the

  • country but it won't be long before this freeway attracts more people creating

  • more traffic and driving demand for even more roads it's kind of an infinite

  • construction loop

  • some places are taking a different approach

  • i'm heading to one of the nation's fastest-growing cities and one of his

  • most popular destinations Las Vegas each year the city of 2 million has to move a

  • rotating cast of 36 million visitors through its streets

  • today the national finals rodeo is coming to town

  • which means extra traffic pushing already crowded streets to their limit

  • instead of building new roads as they do in dallas Nevada's transportation

  • specialists are using technology to make the most of the ones they have we're

  • taking into a place that we call the fishbowl jacobs know is one of Nevada's

  • transportation experts

  • wow this is impressive you know it really looks like we got some real

  • rocket science going on her and we actually do it's a very complex system

  • of hardware and software that we can monitor everything that's going on in

  • the major intersections in the major traffic points in the las vegas valley

  • and are these active 24 hours a day to 24-hour town gotta monitor traffic 24

  • hours a day for all this rocket science

  • the most powerful tool is a device we often take for granted the old reliable

  • traffic light or doing something that most other places in this country

  • haven't tried that's adaptive traffic signal control if we get a lot of

  • traffic on one particular direction or in one particular quarter we need to

  • make changes on the fly so we can distribute the traffic more efficiently

  • that's really a big brother-type approach

  • hundreds of cameras feed real-time traffic data to the fishbowl where staff

  • can adjust 1250 traffic signals to keep the roads moving so you're not adding

  • capacity by building new roads

  • you're just making the existing system smarter that's correct

  • we can get about twenty percent additional capacity by implementing

  • systems like this and for one one-hundredth of the cost of a freeway

  • or a roadway expansion and it's not only cameras monitoring the action as a

  • Saturday night rush art begins i'm heading out to the field with one of

  • Nevada's road managers chuckles island to see how he solves problems on the

  • frontline we do have some traffic backed up over there

  • tens of thousands of rodeo fans are on their way to the stadium it

  • to get all those cowboys and cowgirls to the stadium Chuck needs to make sure

  • that each one of the city's busy intersections gets just the right amount

  • of what she calls green time I am a little concerned about Spencer why

  • that's a pretty long line of traffic

  • so we're gonna do about that and what we're seeing is a lot of empty road way

  • out here huh

  • we're going to steal a little bring time

  • try and get over here that's really interesting way to think about it I I

  • never thought of traffic that way but you're actually thinking of green time

  • as like a scarce resource a finite resource and you're trying to allocate

  • it in the most efficient way possible

  • that's exactly what heaven

  • what we need is at Paradise Chuck calls a fishbowl to order up a new light

  • pattern mount one paradise

  • let's try and hold that one green as long as we can get it i'll be

  • downloading in just a second just no way you can get everybody green it's not

  • going to have so the best we can do is if you do have to stop here i want to

  • get you as many lights down the street as I can before I have to stop you again

  • light by light intersection by intersection Chuck stays one step ahead

  • of grid log and get everyone to the rodeo

  • ladies and gentlemen are ready around in this area lights cowboy

  • out what up a little with him come on

  • the party's over and i'm leaving Las Vegas and who do I see at the airport

  • but that veteran road warrior deanery you all doing here passing through what

  • are you doing here

  • I'm flying back home i'm going to use that I got a flight in about half an

  • hour higher good about Dean like most of us

  • depends on a transportation system that's being pushed to its limits and

  • those limits are put to the test every day on the streets of my last stop

  • Los Angeles when it comes to our transportation triumphs and failures

  • it's the ultimate example la has more cars than any other county in America 12

  • million of them

  • it's a vast fleet that can move us to every corner of the county also 12

  • million reasons why you might not get there in time

  • unlike Las Vegas la doesn't have road smart enough to move all this traffic

  • and unlike Dallas there's no room here to build new freeways

  • it's one more system limited by plans made in another era a hundred years ago

  • most people in Los Angeles traveled by streetcar and they had the largest urban

  • rail network in the world then in the nineteen forties the city abandoned

  • streetcars and began an unprecedented freeway building frenzy this set of

  • aerial surveys shows how freeways were designed to cut through neighborhoods

  • that prompted activist to fight back and block construction of new roads as a

  • result la was left with the worst of both worlds devastated neighborhoods and

  • an incomplete freeway system this original freeway plan promised an

  • additional fifteen hundred miles of road and here's what was actually built just

  • 918 extra miles and the city has had to deal with that shortfall

  • every driver in la experiences 64 hours of delays on average every year nearly

  • three entire days spent stuck in traffic

  • d miles per hour which is certain

  • we're looking at down below as the i-5 freeway where their inching along it

  • probably three miles per hour right listen let me just take a break here

  • I've got a report coming up from the station but once again we want to tell

  • you about that singular it up on the to Commander Tucker street is a city's last

  • radio traffic reporter who still pilots a helicopter to hunt down bottlenecks

  • and so far the east by 210 freeway was backed up to the 118 you know I've been

  • up here doing a traffic watch over Los Angeles for 27 years have you seen a lot

  • of changes in traffic of course the traffic is worse a lot more volume rush

  • hour starts earlier last longer

  • it starts out at some of the freeways coming in from the east at 5am Wow

  • and it probably goes until about 8pm so calling you at rush hour is sort of a

  • misnomer more like rest day yeah even the word Russian i think is appropriate

  • for some reason here in Southern California computers are really

  • independent souls and they they really like having that freedom but also I

  • think that an automobile is kind of a statement about them and who they are do

  • they think they are you can find their identity really what do you think's

  • going to happen over time

  • well I think the freeways will get so slow where a lot of people just decide

  • it's not worth the grief and the stress so hopefully they will start a bracing

  • mass transit

  • a revival of its mass transit system might be Elias best hope to keep the

  • city moving so the city is now investing in a dozen projects like this one

  • you're looking at an old streetcar route that was paved over years ago and now

  • it's being reclaimed for a new light rail line

  • infrastructures cycle of life but these projects are big and expensive and it's

  • hard to imagine the people of Los Angeles giving up their deep-rooted car

  • culture la's and the tangle of roads and freeways another system at the breaking

  • point

  • like many other transportation networks there are plenty of ideas on how to fix

  • this but the question is will we at every stage of our history we have

  • answered the challenge of how to connect the country and move a nation today

  • we're at another crossroads technology offers new solutions but to improve our

  • system will need to invest a lot of money and change old habits this week as

  • a nation will drive 60 billion miles

  • traffic will make three million of us late for work 22,000 free cars will pass

  • through the double hump on the way to every corner of the country so the only

  • averaged 10 miles per hour

  • deanery will earn another 5,000 frequent flyer miles and you'll have a lot of

  • company in the air one quarter of all the flights in the world will take off

  • or land in the United States and in the process airlines will lose 45 thousand

  • pieces of luggage

  • the largest transportation network on earth has its weak spots and it's

  • definitely showing its age but we've managed to keep it up and running and

  • for the most part it still gets us where we want to go

  • as for me my journey across the country is about to end right where it started

  • i'm heading back to New York on the red I'm

  • just one more American on the move

  • America revealed is made possible by the Corporation for Public Broadcasting

  • and by contributions to your PBS station from viewers like you

  • thank you

yeah
