Smart cities aren’t just a dream of the future anymore
解决城市拥堵问题，构建智慧出行大生态
 
Whether it’s across town or across the country, you have plenty of options. Planes, trains and cars are just a few of them. All of these modes (方式) of transportation will soon be improved with the introduction of 5G and smart technology.
Finland’s “robot buses” are an excellent example. Telecom company Nokia has installed (安装) 5G transmitters (传送器) in 15 lampposts (灯柱) along a 1-kilometer route from the company’s head office to a nearby train station. These transmitters control and direct buses, making them fully autonomous, according to Raconteur Media.
In fact, 5G roads have been in development for some time. These roads are lined with 5G transmitters, cameras and other high-tech infrastructure (基础设施). They’re expected to provide many services. For example, the roads can tell electric car drivers the location of the nearest charging point. For children who get bored on long car rides, the roads can transmit movies and TV shows to screens in their parents’ cars.
In addition, being able to monitor and adjust traffic flows could mean the end of traffic jams. “Transport bodies will be able to manage a road network in real time, controlling traffic lights, traffic flow and congestion (拥堵) through automated (自动化的) machine-learning and artificial intelligence programs,” Guy Matthews, director of emerging  technology at CGI UK, a tech consultancy company, told Raconteur Media.
Public transportation is expected to benefit greatly from smart tech. In many Chinese cities, subway riders are more likely to swipe (扫) their phones at the turnstiles (旋转闸门) than they are to use transport cards. A phone app linked to your Alipay account is all you need to take the subway wherever you need to go.
In Seoul, South Korea, a smart station management system has been installed in one of the city’s subway stations. This system has many advanced features, including a 3D map, Internet of Things sensors (传感器) and an advanced CCTV (闭路电视) system to make the station safer and more efficient, according to Arirang News.
And of course, there are the much-awaited driverless cars. These cars will depend on the speed and stability of 5G to operate smoothly and safely. However, we still have some time until we see them on our roads.

无论是遍布城镇还是遍布全国，都可以选择。飞机，火车和汽车只是其中的一部分。随着5G和智能技术的引入，所有这些运输方式都将很快得到改善。
芬兰的“机器人客车”就是一个很好的例子。诺基亚电信公司已从公司总部到附近的火车站，沿1公里的路线在15个灯柱中安装了5G发射机。根据Raconteur Media的说法，这些变送器控制和引导总线，使其完全自治。
实际上，5G道路已经开发了一段时间。这些道路两旁都是5G发射器，相机和其他高科技基础设施。他们预计将提供许多服务。例如，道路可以告诉电动汽​​车驾驶员最近的充电点的位置。对于长途开车感到无聊的孩子，道路可以将电影和电视节目传输到父母汽车的屏幕上。
此外，能够监视和调整交通流量可能意味着交通拥堵的结束。CGI新兴技术总监盖伊·马修斯表示：“运输机构将能够实时管理道路网络，通过自动化的机器学习和人工智能程序来控制交通信号灯，交通流量和拥堵。”英国一家技术咨询公司告诉Raconteur Media。
预计公共交通将从智能技术中受益匪浅。在许多中国城市中，与使用交通卡相比，地铁乘客更有可能在旋转闸门上刷手机。与您的Alipay帐户关联的电话应用程序是您到地铁站所需的一切。
在韩国首尔，该市的一个地铁站已安装了智能车站管理系统。据Arirang News称，该系统具有许多先进功能，包括3D地图，物联网传感器和先进的闭路电视系统，以使车站更安全，更高效。
当然，还有期待已久的无人驾驶汽车。这些汽车将依靠5G的速度和稳定性来平稳安全地运行。但是，我们还需要过一段时间才能看到他们在路上。

Dangers of driverless cars
While many people are waiting for the driveless cars, many others have raised concerns about the safety and job security.
Between 2014 and 2018, there were 88 accidents involving self-driving cars in California, US, according to Business Insider. However, even a small possibility of malfunction (故障) will probably be enough to convince most people to stick with driving their own cars.
If these trucks go driverless, about 300,000 truckers can expect to lose their jobs, according to the Wall Street Journal.
无人驾驶汽车的危险
当许多人在等待无人驾驶汽车时，许多其他人对安全性和工作安全性提出了担忧。
据《商业内幕》报道，2014年至2018年之间，美国加利福尼亚发生了88起涉及自动驾驶汽车的事故。但是，即使故障的可能性很小，也足以说服大多数人坚持驾驶自己的汽车。
据《华尔街日报》报道，如果这些卡车无人驾驶，大约有30万卡车司机可能会失业。
