Six minute english from bbc learning english dot com
Hello
This is six minute english from bbc learning english
I am faill and i am paper here at six minute english
We love discussing new tech one of the most controversial technologies of recent years is driverless st cars also known as self driving cars
Autonomous cars or robot taxes
Many people say they wouldn't feel safe in a car without a human driver
But there are concerns from other road users too pedestrians
Runners and cyclists
How will driverelst cars interact with then is the problem professors stephen bruster for glasgoo university has been working on
He explained more to bb c world service program tech life
If you're outside the vehicle
Right now you can see the driver inside the vehicle
You can wave to them
They can see you
You can make a contcontact
对对
When you come to an authonous ous agal al re's no person in the driving seat
So how do you negotiate
Whether they're going to go
Whether they are going to let you go on my walk to work
I need to cross the road
Usually a drivermakes eye contact with me
They looked directly into my eyes
And then wave me across to wave
Means to raise your hand and move it from side to side
Um a just stiif for saying hello or a way of telling a person to do something luckily feel you usually arrive safely at work
And as yet there aren't no driverless cars in london
But feel how would you feel about crossing that road in front of a robotaxi
But maybe a little bit nervous so might wait for it to go and go behind it or something um
Yeah
I get that
I think maybe as we get more used to these technologies
Will get more used to hang to deal with them and went cross
But in this episode we investigate the tech helping driverless cars communicate on the roads
Will learn some useful new words frated and as usual
You'll find all the vocabulary on our website

But well i have a question for you paper as you mentioned
We don't have self driving cars here in london
Yet so first was the first city to have fully driverless ous robot taxes on the streets
Was it a philadelhia b phoenix or see sanfransyisco
I'm going to say b phoenix
Because i think it's quite a car friendly city
Okay
Well we will find out the answer
But at the end of the program
Because which cidents are often calls by not seeing the oncoming danger professor bruster wants to make driverlst cars more visible
He discussed his work with bbc techllize presenter chris enicos in terof signals
Work in terms of learning dedestrians and runners and cyclists to the intentions of the vehicle
We tested two things
We tested animations and fixed coloured lightings
The animations they work work well for pedestrians
But when it came to ruuners and cyclists
They have much less time to make their decision
So if do do quit glance set a vehicle
You don't really see it
Cyliliand important to alert people to drive a less cars
To alert somebody means to warn them about the potential danger
Some cars do this with animations displays of moving images for example
A green man walking to signal it safe to cross animations alert pedestrians
But are not suitable for runners and cyclists
Who are traveling too fast to react
They only have time for a glance
A glance as something means a quick look so stead
Stestevensteteam used coloured light rings similar to traffic lights to warn cyclists and run as culture is another problem
The meaning of body language can change for example
Handwaving can mean please proceed in one culture
But thank you in another ahmaa l day is a research at the advanced institute to science and technology in south korea
Here amaa t tells bbc servservices ch renow now korean culture is especially suit to self driving cars in south korea
For examples
Jay walking is jy gworar is in britayou know we tend to jay walk a lot
J walking is an american english word
It means crossing the road
Road at a place
Where crossing is not allowed or without taking car unlike britain
J walking is rare in south korea
Making the country is safer for autonomous cars
We've heard a lot about making driverless st cars safer
And with plans to introduce them to london later this year
Well soon see see b safe
They really are here amn't it time to reveal the answer to your question fill now isn't it
You
It was the first first to have self driving cars on the road
And you said it was phoenix
And that is the great anscer phoenix
Arizona was the first city in the world to have self driving cars operating on public roads
And as a human safety driver
And i was also twenty seventeen lelet's k up the vocovery
We've leard and arting with eye contact and directly into someonon's eyes
Yes
To wave it
Someone is a way of saying high by raising your hand and waving it from side to side
If you alert someone
You warn them with potential danger
An animation is a display made up of moving images
A glance is a quick brief
Look at something and finally the american english term jay king
King and ans crossing the road
Way 're not supposed to once again i was six minutes
