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.
