[ ♪INTRO ]

play00:03

Technology infuses nearly everything these days. We have smart refrigerators, smart watches,

play00:08

smart glasses… It might not seem like we need any more smart stuff.

play00:12

But some of these technologies can be really useful, and that’s especially true when

play00:16

it comes to smart roads.

play00:17

Really. There’s a traffic jam of ideas in the pipeline to make infrastructure more intelligent,

play00:21

and to help roads do everything from repair themselves to save lives.

play00:25

Here are three emerging technologies that give new meaning to the term “street smart.”

play00:30

First, some companies are working on roads that can prevent accidents and help drivers

play00:33

who have been in a crash.

play00:34

There are a few ways to do this, and some of them are being tested in Colorado.

play00:38

One strategy is being tested by a company called Integrated Roadways.

play00:41

In 2018, they announced that Colorado’s Department of Transportation had granted them

play00:45

a contract to install Smart Pavement on a roughly 1km stretch of Highway 285.

play00:51

Smart Pavement is a system of concrete slabs embedded with digital technology and fiber-optic mesh.

play00:56

These fibers detect the position, speed, and weight of vehicles.

play00:59

And once it’s installed, a computer communicating with the highway will be able to calculate

play01:03

if a car crashed, skidded off the road, or just pulled aside to take a photo of the landscape.

play01:08

If there’s been an accident, or if a car veered off the highway, routers inside the

play01:12

road will be able to alert emergency services to rush to the scene.

play01:15

Integrated Roadways has already piloted this pavement on a section of road in Denver, and

play01:18

it’s currently collecting information on about 7500 vehicles per day.

play01:23

So if their new, roughly 1km test goes well, this kind of technology could start popping

play01:27

up all over the place.

play01:28

It is worth noting, though, that Smart Pavement isn’t the only way to make a safer road.

play01:32

There’s also a system called V2X, which is short for “vehicle to everything.”

play01:37

It’s short-range wireless technology that allows vehicles to communicate with each other

play01:41

and with objects like stoplights and guardrails.

play01:43

If the network of objects senses something like a bunch of vehicles decelerating, it

play01:47

can send an audio or visual message to the display screens on nearby cars, warning drivers

play01:51

to proceed with caution.

play01:53

For this system to be effective, both the objects and the vehicles need to have V2X

play01:58

capability. But some new cars already have this installed, and other brands plan to add

play02:02

it to their future models.

play02:03

Colorado is also testing out this system, and their first stretch of road with this

play02:07

tech is expected to be completed in 2021.

play02:10

According to one consulting firm working with the state’s Department of Transportation,

play02:13

this tech could make a big impact, too.

play02:15

They say that, if it were implemented throughout Colorado, it could lead to more than 85,000

play02:20

fewer car accidents and 300 fewer deaths over 20 years.

play02:23

Now, traffic is bad, but potholes can be a real pain, too. They’re not fun to drive

play02:28

over, and the really bad ones can even damage vehicles.

play02:30

So in 2010, scientists in the Netherlands tested a potential solution: build roads that

play02:35

can almost fix themselves.

play02:37

To do this, they started with a type of pervious asphalt commonly used in the Netherlands,

play02:42

which is made of stones held together with as little bitumen as possible.

play02:45

Bitumen is a sticky black binder. This kind of asphalt is great for various reasons, but

play02:49

by itself, it still gets cracks and potholes. They happen when the bitumen shrinks and detaches

play02:54

from the stones it’s holding onto.

play02:56

So next, the researchers mixed in tiny pieces of steel wool — the kind you might use to

play03:00

scour burned hamburger off your pans.

play03:02

They took this mixture and used it to pave a section of road. Then, in 2014, after letting

play03:07

it sit for a while, they drove an induction machine over it.

play03:10

The machine created an oscillating magnetic field, which induced an electric current in

play03:14

the conductive steel wool.

play03:16

The electricity heated the steel and melted the bitumen between the stones, and that repaired

play03:21

cracks that might have eventually caused potholes.

play03:23

The scientists say that running the induction machine over steel-filled asphalt every 4

play03:28

years can double the lifespan of the road — taking it from 8 to10 years to 16 to 20.

play03:33

The Netherlands has already used this technology on a dozen other roads, too.

play03:36

And according to one of the scientists, that’s not all this tech can do. It may also be possible

play03:40

to send energy through steel in the pavement, so electric vehicles could charge while at a stoplight.

play03:46

That technology is in the early stages, but car-charging roads are already rolling out elsewhere.

play03:50

In 2018, the world’s first electrified road for charging cars debuted in Sweden. And the

play03:55

way it works is pretty straightforward.

play03:56

#For this road, engineers laid down about 2 kilometers of track in the center of the

play04:00

road, similar to the kind you see on light rail.

play04:03

When you drive your electric vehicle on it, an arm attached to the bottom of the vehicle

play04:06

reaches down and connects to the track. Then, as you drive, the road charges your battery!

play04:11

If you switch lanes, the arm will disconnect, and if you stop, the current will, too.

play04:15

This system is set up so that the electricity itself is on a separate rail about 5 centimeters

play04:19

below the surface, and so that it only flows when a car is attached to that section of the road.

play04:24

That way, people can cross the street without getting electrocuted. Which is always nice.

play04:28

Still, even if the whole area flooded with water or something, the organization behind

play04:32

the project says the current isn’t enough to hurt pedestrians.

play04:35

Now, Sweden is thinking of applying this idea to the 20,000 kilometers of highways throughout the country.

play04:40

But again, this method isn’t the only way to do this.

play04:42

Other companies are testing wireless charging roads.

play04:44

For example, an Israeli company called Electreon has successfully created a driving track studded

play04:49

with copper coils that are connected to the electrical grid.

play04:52

When an electric vehicle outfitted with copper plates passes over them, the interaction between

play04:57

the two electromagnetic fields generates power to charge the vehicle.

play05:01

In 2019, the company announced it would install this technology on a public road in Sweden.

play05:05

And France, the U.K., and South Korea are also testing similar tech.

play05:09

One of the biggest concerns people have about electric vehicles is that there aren’t enough

play05:12

places to charge their batteries. But if roads themselves charged cars, that barrier would

play05:18

basically disappear.

play05:19

So while smart roads may seem unnecessary at first, they could eventually transform

play05:23

the way we drive.

play05:24

They could potentially reduce or eliminate the need for gasoline-powered cars and gas

play05:28

stations. They could reduce the need for frequent road repairs. And they could even save our lives.
