Smart cars

Answer A :

The TravTek navigationsystem is installed in 100 Oldsmobile Toronados, the

visual part of the system is a computer monitor. Through detailed colour maps, it

leads the driver through the town. The map changes all the time, cause a computer

connected to a navigation-satellite, and with a magnetic compass installed, calculates

the fastest or easiest way to your destination. When yellow circles appear in a

particular place on the screen, it means that there is traffic jam here, or there has been

an accident on the spot. The computer receives this information from the Traffic

Management Centre, and it quickly points an alternative route out.

b:

The driver interact with the system through the so called "touch screen". 7000

buisnesses in the area are already listed in the computer, and you can point out your

destination by searching through a lot of menus until you find it, or simply by typing

the name of the street. when the place you want to go are registered you push the make

destination button, and the computer programmes a route, the second after the route

appears on the screen, while a voice explains it to you through the loudspeaker.

c:

The TravTek guides the driver through the traffic. The computer always knows

where you are, and the navigation system makes it impossible to get lost in the traffic,

unless you really want to, and deliberately make the wrong turns. It also guides you

past traffic jams and problems who might crop up around an accident. In a town

where you have never been, you will quickly be able to find your way to hotels,

restaurants, sports arenas, shops and much more, just by looking through the various

menus of the TravTek.

d:

The text definitely prefers the accuracy of the computer to the insecurity and

misunderstandings who occur between two persons. The passage from line 54 and

down clearly shows the point of view (quote): "...a guy on the gas station who, asked

for directions, drawls: "Bee Line Expressway? Ummmm. I think you go up here about

four miles and take a right, or maybe a left..."" The guy at the gas station are described

as the incompetent fool who actually have no idea where he is himself... and his

guidelines, insecure as they are already, will probably also be very hard to remember

because of Ummmm, I think, maybe and or...

Answer B:

Japanese drivers can now find their way almost blindly, if they equip their cars

with a digital map, who shows the position of the car. Based on the position of

satellites, the position of the car is calculated by a small computer in the receiver. The

receiving set in the car is attached to a screen on the dashboard. The screen can show

a map of the entire Japan. The maps are delivered on four laserdiscs, each showing a

part of Japan. All road maps are in colours, and they do not only show the network of

roads. Restaurants and hotels are plot in as well. A small shining dot shows the cars

position on the map.

Answer C: Essay

Smart-car Technology In Denmark

The smart-car system is developed in USA and Japan. The system makes it

almost impossible to get lost, when you are travelling by car . One big question for

countries all over the rest of the world are: Will this kind of technology match our

needs too? Are we able to use this in action. It sounds great, but will it give enough

advantages compared to the price, and compared to other possibilities of solving our

traffical problems. This question will of course also arise in Denmark.

And what can this technology offer to improve in our traffical situation. In

America and Japan it is made to take care of:

Problems which appear when people have to find their way.

Traffic jams, by leading the cars on alternative routes

Problems which appear in connection with accidents

The three problems are very big in these large countries. In the big cities with a

population of several millions, it s very easy to get lost, also if you have lived there for

a long time. The city itself and the complicated network of roads changes all the time,

new buildings sprout up every day. The system who can keep up with this

development, is clearly an advantage. But what about Denmark?

The road network in Denmark can not be compared to the American freeways

at all. Even I would be able to find my way from town to town, cause there are usually

not so many possibilities.

We do not have giant cities, Copenhagen is the largest and I admit that, it can be

big enough! especially to Jutlanders as my self...

But in the public transportation - network in Denmark is very adequate. No

matter where in the country, or in the cities for that matter, you are going, you will be

able to find a bus or a train to exactly that place. If we used the great advantage we

have got in this, it would also take care of a lot of other problems. The main problem

by driving your own car is: Parking. No matter how many new car-parks build, a

parking spot never is to be found. Build in a device who could look up parking spots,

and some people might see an advantage in it. Basically I still see the public

transportation as a much better solution though.

Concerning the accidents and traffic jams I see no problems in American scale

either. There are accidents and traffic jams on the Danish roads too, but the queues

coming with it are usually not so long that a detour pays.

In Denmark we also tries to create other ways to guide the drivers. An example

of this are changeable signs. On the express- and highways, for example the ones

leading to Aalborg, there are signs connected to the Traffic Information Centre, they

show how much waiting time there are if you choose to us the tunnel or the bridge,

which roads that are cut off, in which car-parks there are vacant spots for parking...and

so on - sort of a common TravTek. Another disadvantage that comes with the

TravTek, that is not mentioned in the text, is that the sattelite reciever and the

computer needs a lot of space in the car. I have seen one, and it occupies most of the

trunk in an ordinary car.

Bottom line: I consider the smart-car a great development for nations such as

USA, they will have great advantages of them, but for smaller countries as Denmark I

find that there are other things who offers a better solution.
