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.
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.
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.
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...
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.
