How does the internet create smarter cities?

  • The cities are expected to add another 2.5 billion inhabitants over the next three decades.
  • Clever waste disposal technologies for police officers revolutionize the way cities work. The latest innovations are made.

There are growing urban populations worldwide, but cities struggle to keep up.

Technology is being used to handle rapid urbanisation and to build smarter cities as the silent force, which has revolutionized our environment.

Raconteur’s data graphic today looks at how the Internet of Things (IoT) has become a vital component of making cities more secure, prosperous and resilient, and shows how this will have an increasing effect on both people and the planet.

Intelligent city development

Since 1950, there have been nearly six times more people living in cities from 751,000 to over 4,000 million in 2018— more than half the population of the world. The cities are planned to add an estimated 2.5 billion inhabitants in the next three decades.

This continuing shift to urban areas is placing greater pressure on both public and urban planning systems. Consequently, cities use technological-and data-driven solutions to reduce the additional strain caused by this growth.

Innovations in smart cities

  • Significant growth is expected in new innovations as: Officer wearable: Adequate equipment’s that provide police officers with information in time to improve visibility, and make better decisions on the global CAGR (2017-2032):62% of smart city development costs to hit $158 billion by 2022.
  • Wearable officers: apps that provide real-time information to police officers to raise awareness and improve decision-making Global CAGR (2017-2022): 62%
  • Open data: data that can be accessed by anyone contributing to public and intelligent city projects openness Global CAGR (2017-2022): 25%
  • Smart trash collection: Solar-powered smart bins equipped with sensors allow waste collectors to control and optimize their fuel consumption Global CAGR (2017-2022): 23 percent 23 percent
  • Smart City platforms: solutions to better manage smart Cities Global CAGR (2017-2022) through data collection from different fields such as contamination rates and traffic density: 23%

Such innovations could lead for cities ready to accept a wide range of transformational effects.

Effect assessment

Smart city innovations have the ability, while creating new opportunities for economic development, to enhance citizens ‘ health and well-being.


In order to improve public safety, cities are implementing software to identify potential hotspots and prevent crime in real time, track gunshot fire and anticipate police actions.

According to McKinsey, using these techniques could reduce violence levels and casualties by 8-10%, saving up to 300 lives per year in cities with Rio de Janeiro-like population size and crime rates.


The greater the IoT logistics and transport industry grows as more vehicles enter this IoT ecosystem, with investment projected at over $43 billion by the year-end.

The city begins to get more investment from new innovation such as intelligent roads which support automated vehicles. Such roads can communicate and improve the safety of drivers with automated vehicles–possibly reducing by 30 minutes the total travel time.


Technology has developed new approaches for chronic disease prevention and treatment.

In China, facial recognition drones are being used to track people suffering from coronavirus to ensure that quarantine is not violated and the virus does not spread.

Data-based health initiatives for the maternal and child health, driven on the use of data to identify and direct new mothers, are however the most effective use of technology. Preventing disease intervention has been particularly effective in cities such as Lagos, Nigeria, with a high burden of illness and low access to care.

The risk of chronic disease is reduced by these new technologies. The consequence is a calculation of one year of “clean” lives lost as a result of the contracted disease throughout the main metric disability-adjusted life years (DALY). The implementation of data-based maternal care strategies, for example, could reduce DALYs by over 5%.


While a large proportion of greenhouse gas emissions come from cities, city solutions by reducing electricity and heat production can reduce them by up to 15 percent.

In order to reduce water consumption, smart cities will also play a key role. Smart irrigation systems, water leakage, quality control and consumption can save a city from 25-80 litres of water per person per day.

Intelligent cities regulated by people

The through use of 5 G will lead to these economic and social advantages. 5 G will allow smart cities to scale, by offering high-speed connectivity and supporting more apps, which makes it a key element in the next wave of creative intelligent city projects. This is, however, not the only one to be used.

Many newer versions of intelligent cities are focused on justice and social inclusion values. For instance, for its inclusive and collaborative approach to smart city initiatives, Vienna consistently leads the Smart Cities Index. The city supports socially inclusive solutions which take people of all socio-economic backgrounds and age groups into account.

Vienna is only one of many European gateway locations that lead the way in the amount of investment in the intelligent city project. Indeed, by 2025, up to 53 million active IoT connections are projected in the continent.

While each city has another strategy, citizens will prove their main asset. It is evident that people are at the core of their true potency by thriving new, clever city applications that are the new norm in the forthcoming ten years.
