The chores of Navigation

Every time I drive out to play, I will encounter many difficult events related to navigation. Over the past few years, the roads in the motherland have developed rapidly. Even if I am an old driver, when I come to a strange place, it is also often unable to find the north, so it is essential to have a GPS. Even if it is local, you may not be able to find all the places, so it is not surprising that many taxis are equipped with navigators.

I remember the first time I bought a car in Shenzhen, it was quite smooth. Basically, I ran along the high speed. When I came back, I had a fever and wanted to change the road. At that time, I bought a mobile phone. It was from a Chinese brand. Now I have fallen down, and it carries a navigation. It was also a selling point, So I thought about it. In the end, what is the problem? It is hard to find the highway. As long as there is an exit, you will be reminded continuously, or you will not be asked to go up when there is a high-speed entrance. At that time, I was a novice, so I was so timid that I could not believe the street signs. As a result, I almost crossed several towns in Shenzhen and Dongguan, it was hard to go to Humen, and looked at Humen Bridge Head, but did not know how to go up, finally back to the most basic navigation, the mouth under the nose, just to find the right way.

Another time in Shenzhen is this year. I had a navigator and a map of daootong, which is quite useful at ordinary times. The road to Shenzhen has gone through many times, so it didn't use navigation at the beginning. When we were about to go to a place in Shenzhen, we couldn't get started, so it went crazy. At that time, although there were neon lights flashing in the dark, the direction was even more invisible. I had to take out my cell phone. I used Google maps when planning the line. The effect was quite good, but because there was no voice navigation, I should be able to identify it on a simple road, once you come to a complex city, you don't know where to turn. I still haven't changed my note. I don't know how to use an Android phone in my industry, but I still can't follow my Google map. I hope I can find a High Speed. Although I am looking closer and closer to my target, however, complex roads and surging traffic make you unable to embark on the right path. Later, I was afraid of fuel consumption. I ran to the gas station to refuel and was lucky enough to meet a good guy who promised to take me to the high-speed entrance. Thanks to this good guy, I followed his car closely and finally broke through the re-encirclement and reached the high speed leading to the destination.

In fact, for drivers with some experience, as long as there is no problem with the road signs on high-speed and general national roads, they are afraid of complicated overpasses or turn turns in the city. Sometimes, you know that you only need to turn your head or left to reach the target, but you just cannot find the place where that port is located. In general, it is assumed that drivers are local citizens and they are very clear about every design of the road. Therefore, there will be no clear identification, and it will be too difficult without GPS.

However, if you have GPS at hand, you may also encounter an issue, that is, the map cannot be updated. If there is a mobile phone or tablet, maps can be updated online, so that maps can be updated, but these maps are generally not voice navigation or not easy to use, and these smart phones have a power consumption problem, you have to pick up a car charger, you have to get a bracket, sometimes you have to answer the phone, charging and working will make the cell phone heat too large, resulting in a crash, it is not very convenient anyway. Professional devices like on-board GPS are still easy to use, but it is too troublesome to update maps. Various map manufacturers may have many restrictions on map data acquisition to protect their copyright. Some manufacturers only support upgrading to the designated merchant, while some also provide online upgrades, but it is only a small number of versions. However, the brand, model, and size of GPS on the current market are varied, and users will carry maps when purchasing GPS. However, users may not know whether the copyright of the map is legal, some are known as genuine and free upgrades for several years, but the actual implementation is not as expected. Therefore, many people may not be able to use GPS for two or three years. It is not a bad thing, but a map cannot be upgraded, not just a matter of copyright, sometimes it is possible that the vendor no longer provides the map of the version of the device you hold, because in the economic aspect, this is also the inevitable choice of the vendor.

Fortunately, with the rapid development of mobile Internet over the past few years, many large Internet companies have realized the business opportunities of map services and started to launch map services with voice navigation, for example, Baidu, sogou, and other major manufacturers also have audio navigation products. Although the actual use of the products is not good, after all, the products and services will surely get better and better in the future. In addition, the market environment will encourage other professional navigation service companies to pay more attention to service improvement and provide more convenient and excellent products.

We hope that our own Beidou system will be improved one day, and all roads will provide traffic information in real time. Vehicle-mounted devices may directly accept the information and plan reasonable travel routes in real time, at that time, there will be something different.
