Smart cities aren’t just a dream of the future anymoreWith intelligent systems and new-age transit n

当然，将我们目前的城市变成未来的智慧城市将需要时间和金钱。但是，正如我们已经看到的那样，世界上越来越多的城市已经在以小规模方式采用智能技术。例如，中国正在对上海和广州等大城市进行投资，以使其“更智能”。不久之后，甚至会有更多的城市开始开发自己的智能基础设施。
 
背景信息：
Chinese cities are getting smarter
Several Chinese cities have already started using smart technology to improve the lives of their citizens.
Hangzhou, in Zhejiang province, started a project called “City Brain” in 2016.
City Brain – which was created by Alibaba, one of China’s biggest tech companies – uses a network of cameras and sensors spread across the city to collect data on road conditions.
This data can be used in a number of ways. For example, the system can track ambulances and see if they are on their way to local hospitals. If they are, red traffic lights in their paths can be changed to green to help them reach the hospital faster.
In Shanghai, smart tech is being used to make parking your car easier. Huawei technology company has introduced an app that allows users to find parking spots with wireless transmitters (无线传输器) attached. The app can tell you where the nearest empty spot is.
中国城市变得越来越聪明
中国有几个城市已经开始使用智能技术来改善其居民的生活。 
浙江省杭州市于2016年启动了一个名为“城市大脑”的项目。
由中国最大的科技公司之一阿里巴巴创建的城市大脑使用遍布整个城市的摄像头和传感器网络收集路况数据。
该数据可以多种方式使用。例如，该系统可以跟踪救护车并查看救护车是否正在前往当地医院。如果是这样，可以将其路径中的红色交通灯更改为绿色，以帮助他们更快地到达医院。
在上海，智能技术正在被用来简化停车位。华为技术公司推出了一款应用程序，该应用程序使用户可以通过连接无线传输器来找到停车位。该应用程序可以告诉您最近的空白点在哪里。
