Technology on multi-vehicles
The technology on multi-vehicles has changed a lot since the 90’s. Although this leads to human a huge help for transportation, there are still pros and cons on this stage. Just like how GPS satellites work.
On the one hand, there are quite a lot of pros. Let say the taxis and some cars, they all have GPS/GPRS machines on their vehicles. GPS is a mini electrical version of the ordinary maps. It could be called as GPS satellites when we use it for location locator on our phones as well. Back to the main point, GPS has already replaced the ordinary paper maps people have used before. This avoids finding maps in a middle of your driving, opening up (unfolding) massive maps since the GPS machine is already settle down in front of you. It helps people a lot when they cannot remember how to get to their destination as well. This is very efficient to people who often travel. In addition, what people like about GPS or why people use GPS instead of an ordinary map are, all the GPS machines have sound, image, video and text! This is how data is conveyed. Sound is to draw our attention to the map by means of a sound. Image is a visual representation of the route. Video is to convey a moving image, for example, showing us should we turn left or right when we head to a diverge road. This is always useful when people who have not been driving for too long. Then, text is a method of conveying meaning using characters and instructions can be given. However, it is just an electrical machine, there is always a chance that machines break down all of the sudden, and people need to prepare well to prevent the problems.
