Leveraging Computer Vision For Effective Crowd Management In Smart Cities



Leveraging Computer Vision For Effective Crowd Management In Smart Cities

Government organizations can implement computer vision in smart cities to maintain social distancing and avoid stampedes and other disasters in crowded areas.

As the global population continues to grow at an alarming rate, crowd management becomes an increasingly challenging task. The global population is reportedly projected to reach 8 billion in 2025. Global trends also indicate that the population in urban areas has been growing steadily over several years. This suggests crowd management can be even more difficult in urban areas. Government organizations can tackle this issue effectively by developing smart cities that use multiple cameras, low-power sensors, and artificial intelligence. Combining these tools with computer vision can make smart cities even more advanced. By implementing computer vision in smart cities, governments can precisely monitor public places and create strategies for effective crowd management.

Government organizations and authorities can use computer vision in smart cities to identify people and objects, assess the motion of vehicles and predict congestions, detect crowded areas, and more. Furthermore, computer vision applications will offer real-time insights that will assist governments in making decisions for smart cities. Smart cities are already benefiting from computer vision by implementing smart parking systems and maintaining law and order. Crowd management will be another major use case for computer vision in smart cities.

Applications of Computer Vision in Smart Cities

Here’s how governments can utilize computer vision in smart cities:

Maintaining Social Distancing

Ensure Social Distancing Since the beginning of the COVID-19 pandemic, healthcare experts around the world have advised us to ensure social distancing of at least 6 ft along with wearing masks. However, it can be quite difficult to maintain social distancing in crowded cities. In this case, smart cities can use computer vision to plan their infrastructure to ensure social distancing in crowded places. For instance, Numina has developed a computer vision-powered tool that offers multi-object tracking in smart cities. The company had tweeted a video that shows how New Yorkers were trying to practice social distancing, but the narrow sidewalk space made it a daunting task. Governments can use such real-time data to identify issues that could be overlooked.

Avoiding Stampedes in Crowded Areas

Government organizations can use computer vision in smart cities to monitor crowded events like concerts and live sports venues where chances of stampedes are quite high. In these scenarios, computer vision will provide real-time estimates like the number of people and crowd density. Such data can be used to avoid stampedes and other disasters as well as assist in controlling the crowd.

Although the implementation of computer vision in smart cities can be effective in crowd control, many of us would be concerned about the invasion of privacy. Citizens of most countries will be worried about their governments using advanced technologies to gather real-time visual data about them. To address this issue, governments need to develop a proper framework to ensure that sensitive data can be accessed only by select high-level officials and that such data will not be misused.

Artificial Intelligence in the 4th Industrial Revolution



Artificial Intelligence in the 4th Industrial Revolution

Artificial intelligence is providing disruptive changes in the 4th industrial revolution (Industry 4.0) by increasing interconnectivity and smart automation.

Industry 4.0 is revolutionizing the way companies manufacture, improve and distribute their products. 

What Makes Artificial Intelligence Unique?

Artificial intelligence (AI) makes it possible for machines to learn from experience, adjust to new inputs and perform human-like tasks.

It allows computers to think and behave like humans, but at much faster speeds and with much more processing power than the human brain can produce.

AI offers advantages of new and innovative services, and the potential to improve scale, speed and accuracy. 


There are 3 types of artificial intelligence:

  • Artificial narrow intelligence (ANI), which has a narrow range of abilities.

  • Advertisement
  • Artificial general intelligence (AGI), which is on par with human capabilities.

  • Artificial superintelligence (ASI), which is more capable than a human.


Artificial intelligence can also be classified as weak or strong. 

Weak AI refers to systems that are programmed to accomplish a wide range of problems but operate within a predetermined or pre-defined range of functions. Strong AI, on the other hand, refers to machines that exhibit human intelligence.


Artificial intelligence has several subsets:

Most AI examples that you hear about today – from chess-playing computers to self-driving cars – rely heavily on deep learning and natural language processing.

What is the Fourth Industrial Revolution?


The Fourth Industrial Revolution is the current and developing environment in which disruptive technologies and trends such as the Internet of Things (IoT), robotics, virtual reality (VR) and artificial intelligence (AI) are changing the way modern people live and work. The integration of these technologies into manufacturing practices is known as Industry 4.0. 

The first industrial revolution used water and steam power to mechanize production.

The second used electric power to create mass production.


The third used electronics and information technology to automate production.


The fourth Industrial revolution is characterized by a fusion of technologies that is blurring the lines between the physical, digital, and biological spheres, with rising emerging technologies, as real AI, Narrow AI/ML/DL, robotics, automation, materials science, energy storage, the Internet of Things, autonomous vehicles, 3-D printing, nanotechnology, biotechnology, neurotechnology, cognitive technology, and quantum computing. It implies radical disruptions to everything, industries, jobs, works, technologies, and old human conditions. In its scale, scope, complexity, and impact, the AI transformation will be unlike anything humankind has experienced before.

The Role of Artificial Intelligence in the 4th Industrial Revolution

Artificial intelligence is making companies make the best use of practical experience, even displacing traditional labor and becoming the productive factor itself. 

It offers entirely new paths towards growth for manufacturing, service, and other industries, reshaping the world economy and bringing new opportunities for our societal development.

As AI begins to impact the workforce and automation replaces some existing skills, we’re seeing an increased need for emotional intelligence, creativity, and critical thinking.

Zvika Krieger, co-leader of the World Economic Forum’s Center for the Fourth Industrial Revolution.

Deploying AI requires a kind of reboot in the way companies think about privacy and security, As data becomes the currency of our digital lives, companies must ensure the privacy and security of customer information.

Businesses will need to ensure they have the right mix of skills in their workforce to keep pace with changing technology.
