Smart City Prediction for 2020: By 2020, Use of a single city wide digital platform to unify all operations, data aggregation/analytics, and actions across agencies will become popular. This will pull data from all city sensors, cameras, end points, databases, etc. and then aggregate that data into a single source, all in real-time. This data will then be pushed back out for immediate use by city leaders, agencies, businesses (including design firms), universities and even citizens to take immediate actions that result in better outcomes for all.

The world’s large cities will pose our greatest challenge—and greatest opportunity—in the next century. Today there are 21 “megacities” with more than 10 million people, and more than 1 million people move to cities every day. By 2050, 70 percent of the world’s population will call a major city home. But today, cities waste an estimated $39 billion in water, gas and energy resources. As demands on resources and infrastructure grow, how will cities provide energy, water, transportation and other critical services for so many people? Smart cities start with a smart public infrastructure to deliver clean water, dependable power, safe gas, and efficient public lighting. And as they free up resources by intelligently delivering essential services, they are able to invest in other services to improve quality of life. In smart cities, many different stakeholders must work together to provide the best technology solutions. Network operators, managed service providers, system integrators and technology providers all have a role to play in working with governments to enable smart city solutions.

5. Smart Building:

The Internet of Things is also changing building management throughout cities by introducing smart building devices and solutions. Office building managers can save money and provide better service to tenants by incorporating systems like remote monitoring, smart landscaping, IoT physical security and appliance maintenance. According to recent research, buildings consume 70% of the world’s electricity, resulting in enormous waste due to generation distribution, construction, design and operational efficiencies.

6. Smart Surveillance:

New services such as remotely connected CCTV and automated incident detection allow a quicker response to threats. IoT led crowd management solutions help protect city inhabitants in busy, crowded areas. IoT physical security can include intelligent monitoring, tampering alerts, perimeter protection, facial recognition and automobile tracking.

7. Smart Cities Transport:

The growth and success of IoT-based applications has introduced us to new bike sharing scheme, where people can share access to better bikes. Moreover, users can easily share transport. The widespread adoption of electric cars will be instrumental in widely adopting the city center car.

8. Environmental Detection:

Environmental change is affecting cities and their inhabitants more regularly. This brings new challenges for city planners, such as the need to improve air and water quality, and control noise pollution to create a healthy and enjoyable environment for city inhabitants

9. Information Beacons:

This technology is assisting towards converting city assets to location-aware information portals. Consumers can easily receive real time transport information or special offers from local businesses, owing to some of the new services which are emerging.

10. Smart Social Housing:

The IoT-based systems that exists today make it possible to introduce low cost monitoring to social housing. This in turn helps in providing utmost satisfaction to the tenants, whilst reducing the associated costs for landlords.

11. Smart Cities Commerce

Smart cities enable local businesses to thrive and citizens to be engaged by them in innovative new ways, increasing both economic outcomes and citizen satisfaction. Business zones can be managed appropriately by the city, with deliveries and other services coordinated with the businesses using them.

12. Smart Roads using IoT:

Intelligent Highways with warning messages and diversions according to climate conditions and unexpected events like accidents or traffic jams. Smart roads , also known as smart highways , is a term used to describe roads that use sensors and IoT technology which makes driving safer and greener. Smart cities and self-driven cars of the near future would not be ‘smart’ enough without smart roads.
