Digital twin- Foundation of Smart city

Cities are rapidly growing in size and population demanding for proper, sustainable management of humans, infrastructure, technical advancements to get a better socioeconomic future. A Smart city digital twins paradigm will create a real-time intersection of reality-virtuality. 

The connectivity offered by the Internet of Things (IoT), spatiotemporal information and virtualization of the city all together makes a city smarter over time.

Energy consumption, security monitoring, land use planning, waste management, trouble-free routes, infrastructure management are the benefits of using Digital twin in Smart City planning. 

Digital twin, in short, is a replica of reality. A fully functional virtual model based on the real conditions is used in planning and analyzing the impacts of changes for a better future. 

The journey so far

World's first Smart Nation initiative by the Singapore government has implemented digital-twin project known as Virtual Singapore. A $73 million data rich living replica of the actual city is made. 

Similarly, in June 2018, the city of Amsterdam presented digital twin of the Dutch foot stadium, Johan Cruijff Arena with the help of geo-ICT ( its GIS and communication technology company).

Amravati in India has adopted the latest Smart city platform of City Zenith. It is said that Smart World Pro will provide a single platform for government, business and citizens. Cityzenith is going to collaborate with JV in India, AEC Digital Studio. Till the end of 2019, the first phase is expected to be complete. 

Jaipur, India has embarked its own digital twin initiative. Jaipur did not permit Google to map their city and captured their data using Lidar backpacks.

Interest of companies

Microsoft is improving its IoT capabilities using Azure IoT platform.  Privacy and security is an integral part of the Azure platform; customers will get next generation IOT solutions. 

CAD and CAM companies Autodesk and Bentley have enhanced their 3D CAD applications. Digital models of buildings, roads and other infrastructure could be precisely prepared using them. 

Siemens and computer-aided engineering (CAE) provided services and products in developing digital twins. 

Some major Components

Internet of things(IoT): Every device of a smart city is connected to the internet, providing a proper medium for communication. 

Sensors: The ubiquitous sensors of a Smart City collects the data and performs various operations. The data is visualized and used in multiple scenarios.  RFID and wireless sensors, optical cable sensors are multiple forms of sensors used to gather information. 

Operational intelligence: Artificial Intelligence and machine learning, machine to machine interaction helps in problem-solving and making sense out of the massive data present. Intelligent Traffic management is an example. OI software learns from past actions through Artificial Intelligence and machine learning and improves its decision-making processes. 

Cloud computing and Blockchain:  Cloud computing helps in handling a large amount of processing and provide backup functions.  Blockchain enables a secure data flow. Trusted transactions, secure billing are benefits of Blockchain. 

The virtual replica, when compared with smart maps, helps the users to visualize, process and analyze complex data. Digital twin is the foundation of the smart city.
