Currently, the process of urbanization worldwide continue to advance. With the development of Internet and information technology, with the support of the cloud platform, big data and networking and other technology, the first to be born in the United States under the concept of "smart planet" "smart city", has become the development trend of today's world city construction countries and choose. This article will share the wisdom of the world's top ten cities Big Data Applications everyone ......

Dubuque
Dubuque City is America's first smart city, is also the world's first smart city, which is characterized by emphasis on intelligent building. In order to keep the city livable Dubuque advantage, and there is greater development, the city government in cooperation with IBM, plans to use networking technology to digitize all of the resources of the city and connected, water, electricity, oil and gas in commercial, transportation and public services, and then through the monitor, analyze and integrate various data intelligently respond to public demand and to reduce energy consumption and costs the city.
The city first to complete the construction of hydropower resources of the data, to the city's shops and households to install water and electricity meter CNC, not only recording resource usage, but also the use of low-flow sensor technology resources to prevent leakage. The instrument will record data in a timely manner to reflect the integrated monitoring platform for analysis, integration and public display.

new York
Through data mining, effective fire prevention. According to statistics, there are about 1 million New York buildings, an average of about 3000 serious fires occur every year. New York Fire Department will factors that could cause house fire subdivided into 60, such as whether it is poverty, low-income family housing, housing construction years old whether, if the building has elevators.

Remove less hazardous small single-family house or townhouse, analysts of the city need to be inspected 330,000 buildings were scored separately by a specific algorithm to calculate the fire risk index, a division of key monitoring and checking objects. Currently data monitoring program expanded to more than 2400, the densely populated high places such as schools, libraries, also covered. Despite the public on the relationship between the effectiveness of data analysis and preventive measures of doubts, but the number of fires is indeed declined.

Chicago
通过“路灯杆装上传感器”，进行城市数据挖掘。在人们的生活里，无处不在的传感器被应用在了芝加哥市的街边灯柱上。通过“灯柱传感器”，可以收集城市路面信息，检测环境数据，如空气质量、光照强度、噪音水平、温度、风速。芝加哥城市信息技术委员会提供的资料表明，“灯柱传感器”不会侵犯个人隐私，它只侦测信号，不记录移动设备的MAC和蓝牙地址。
在今后几年“灯柱传感器”将分批安装，全面占领芝加哥市的大小街区，每台传感器设备初次采购和安装调试成本在215～425美元之间，运行后的年平均用电成本约为15美元。该项目得到了思科、英特尔、高通、斑马技术（Zebra Technologies）、摩托罗拉以及施耐德等公司的技术和资金支持。

西雅图
利用数据节省电力能源。该市与微软和埃森哲（Accenture）合作了一个试验项目，以减少该地区的能源使用。该项目收集并分析从市区建筑物管理系统中得来的众多数据集，通过预测分析，找出哪里可以减少能源使用，或者根本不需要使用能源。项目的目标是将该地区的电力消耗减少25%。

伦敦
利用数据管理交通。在2012年奥运会期间，负责运行伦敦公共交通网络的公共机构“伦敦运输（Transport for London）”，在使用者增加25%的情况下，使用收集自闭路电视摄像机、地铁卡、移动电话和社交网络的实时信息，确保火车和公交路线只有限地中断，从而保证交通顺畅。

格洛斯特
也是充分利用了传感器，建立了“智能屋”试点。传感器安装在房子周围，传回的信息使中央电脑能够控制各种家庭设备。智能屋装有以电脑终端为核心的监测、通讯网络，使用红外线和感应式坐垫可以自动监测老年人在屋内的走动。屋中配有医疗设备，可以为老年人测心率和血压等，并将测量结果自动传输给相关医生。

阿姆斯特丹
是世界上最早开始智能城市建设的城市之一，同时是欧洲智慧城市建设的典范。作为荷兰最大的城市，阿姆斯特丹共有40多万户家庭，二氧化碳排放量占全国的三分之一。
为了改善环境问题，该市启动了WestOrange和Geuzenveld两个项目，通过节能智慧化技术，降低二氧化碳排放量和能量消耗。
为了节省能源，启动了智能大厦项目，在未给大厦的办公和住宿功能带来负面影响的前提下，将能源消耗减小到最低程度，同时在大楼能源使用的具体数据分析的基础上，使电力系统更有效地运行。为建设可持续公共空间，启动了气候街道（The Climate Street）项目，缓解乌特勒支大街的拥堵。

斯德哥尔摩
在治理交通拥堵方面取得了卓越的成绩。瑞典国家公路管理局和斯德哥尔摩市政厅通过智慧交通的建设，既缓解了城市交通堵塞，又减少了空气污染问题，现在智能交通系统已经成为斯德哥尔摩的标签。
该市在通往市中心的道路上设置了18个路边监视器，利用射频识别、激光扫描和自动拍照等技术，实现了对一切车辆的自动识别。借助这些设备，该市在周一至周五6时30分至18时30分之间对进出市中心的车辆收取拥堵税，从而使交通拥堵水平降低了25%，同时温室气体排放量减少了40%。

哥本哈根
素有“自行车之城”称号，在绿色交通方面成绩斐然。为促使市民使用二氧化碳排放量最少的轨道交通，该市通过统筹规划，力保市民在家门口1公里之内就能使用到轨道交通。对1公里路内的交通，推广使用一种智慧型自行车。
这种自行车的车轮装有可以存储能量的电池，并在车把手上安装了射频识别技术（RFIT）或是全球定位系统（GPS），可汇聚成“自行车流”，通过信号系统保障出行畅通。与此同时，市政府大力完善沿途配套设施建设，如建立服务站点、提供简便修理工具等，为自行车出行提供便利。

里昂
该市与IBM的研究人员联手建立了一个可以帮助减少道路交通拥堵的系统，使用实时交通路况报告来检测和预测交通挤塞。如果运营商看到可能会发生交通堵塞，就可以相应地调整交通信号，以保持平稳的车流。该系统在紧急情况下尤其有用，比如在救护车前往医院的途中。随着时间的推移，系统中的算法将从最成功的建议中“学习”，并将这些知识应用到将来的预测当中。
We can see from the above case, the wisdom of urban development is also the future trend, countries have introduced smart city construction plan, in order to promote the rapid development of information technology, so as to achieve the purpose of the new round to seize the commanding heights of the IT industry.

To avoid remaining passive in the new round of competition in the information technology industry, we also need to embrace the wisdom of the city this trend. The smart city infrastructure lighting industry into the construction of smart city entry point increase in the number of lighting fixtures, lighting control requirements become more complex, will be presented greater challenges and opportunities for the future management of the city's fine, then how should we do it?
