The demand for modern cities is increasing all over the world. Gradually every city is trying to transform itself into a smart city. So we are also very curious about these smart cities. How does this smart city work? Would you like to know?
Let us guide you through 11 things to know about smart cities in this article.
1. What is a Smart City?
A smart city represents a better government with technical thoughts which make the city smarter. Although a smart city is a modern area with very good technology, good connection of transportation, and better methods of connecting people to the government.
It improves operational efficiency through information and communication technology – i.e. ICT. All information is also used to share with the public and provide better quality government services and citizen welfare.
In addition to the technology used by smart cities to easily troubleshoot and find out more about the city, data analysts are also needed to evaluate the information provided by the city’s systems.
Optimizing city performance, driving economic growth, and improving citizens’ quality of life using smart technology and data analytics are key goals of future smart cities. Smart cities are valued based on how they develop or leverage technology, not how much technology they may have. But the success of a smart city indeed depends only on its ability to create a strong relationship between its government bureaucracy and regulations and the private sector.
This relationship is most necessary because the government does not cover much of the work that can be done to create and maintain a digital data-driven environment. Surveillance equipment, This system mainly use for busy streets , in CCTV cameras. Also this is used for companies with sensors.
However, Cameras, technologies and also inputs with surveillance is used to company differently. And this features mostly used in smart cities. There are many features include building an infrastructure based on technology, namely-
- Environmental initiatives
- Effective and highly efficient public transport system
- Planning a city that is self-reliant and progressive
- People able to live and work in cities use their own resources
2. Features of a Smart City:
Characteristics of a smart city may include its energy conservation and environmental efficiency. For example, the use of street lights on the road as per the purpose i.e. when the road is empty, the lights are dimmed.
With such an approach, technology can improve everything from operations to maintenance and power supply planning. In terms of better quality transportation, smart cities see traffic management, which monitors traffic flow and prevents roads from becoming too congested based on time of day or rush-hour schedules.
This is another aspect of a Smart City. Transit companies are very adept at coordinating services and meeting rider needs in real-time and focus on improving rider satisfaction. Ride-sharing and bike-sharing are also very common services you can easily see in a smart city.
Smart cities allow various advanced technologies in various applications, including automation, machine learning, and lots. Suppose if someone is looking for a place to park a car. Then that person can easily find a parking space through this technology. Besides, anyone in the city can get permission to use digital payment.
Smart City’s best service is an internet-enabled garbage collection and bin system. This makes it easier to maintain the cleanliness of the city. Smart cities can also use these technologies to address climate change and air pollution as well as waste management and sanitation through fleet management systems. But a truly smart city has to be part of a well-planned, state-of-the-art technology.
Legacy city infrastructure can be modified and retrofitted and new buildings can be constructed with sensors to ensure public safety with real-time space management.
Apart from this, the structural health of buildings can also be monitored.
People can notify officials through the City app if they need repairs to buildings and other public infrastructure such as potholes. In fact, smart cities can connect all kinds of services to provide connected solutions for citizens.
3. History of Smart Cities:
But the emergence of smart cities was a long time ago. Cities like Harappa and Mahenjodaro were also called smart cities. Actually, the concept of a smart city started in the 1960s and 1970s over three phases. The impact of technology has led to the first phase of smart cities with technology for use in everyday life.
Then the US Community Analysis Bureau published reports using databases, aerial photography, and cluster analysis to collect data, direct resources and services, and reduce poverty. This was the first phase of Smart Cities.
In the second phase of Smart City, we look at how municipalities can create solutions using smart technology and other innovations. The third stage is technology providers, which take control away from city leaders and create a completely different model based on public opinion that enables social inclusion and community participation.
Vienna inspired the model. The model allows local citizens to invest in local solar plants while also working to address gender equality and affordable housing issues. Which formed a partnership with Wynn Energy Company.
30,000 citizens created through the 2020 Vancouver City Action Plan. Its influence still continues around the world.
4. Smart Transportation of Smart Cities:
Advanced technology is used in transportation. In other words, smart cities implement a traffic flow management system, which can combine city-centric control systems with traffic lights and sensors. Useful for knowing traffic volumes at various intersections and adjusting light timings based on how well traffic flows on the road.
Systems capable of maintaining time consistency, eg, can monitor the condition of major highways and major roads (or receive condition reports) and adjust timing on major highways and alternate routes to compensate. These systems are useful for buses or other vehicles.
Different parts of cities are provided with a parking-meter network. Parking meters have many uses. For example – parking spots help guide the driver and are available at any time of the day. Each parking spot is connected to sensors or other monitors, which communicate with a central server and a user app. This way, people can know in advance when parking spots are available. AI powers such meters.
In this way, the parker is able to easily charge for automatic spot usage and advise users and potential law enforcement in advance when the meter expires.
5. Advanced Toll System of Smart cities:
Another advanced system used in the city is the Smart Toll. Roads are also provided through this toll. By adding sensors to the tolls, the toll is automatically deducted from the user’s account when a vehicle crosses the toll plaza.
Again, it is possible to evaluate the tolls by adjusting the variable based on the traffic conditions. This could lead to the implementation of express toll lanes that monitor traffic and charge more based on lane usage.
6. Smart Energy for Smart Cities:
In a smart city, improved energy is the key goal of any electrical grid to provide the required power efficiently and minimize downtime and losses in the event of faults.
Some utilities in the city may opt to use microgrids. Microgrids comprise groups of interconnected loads and sources connected to the wider grid. Such microgrids are also very useful as backups.
Home energy control can be easily managed through advanced energy systems. No utility crew even needs to go out to turn it on or off. Smart meters also offer benefits in allowing differential rate provisioning.
If one consumes more during peak hours, a consumer can be charged more and can balance his electricity consumption through time access.
7. Privacy Concerns in Smart Cities:
Smart cities strive to keep their citizens’ data secure and locked. The proliferation of sensors and data monitoring in many aspects of people’s lives has raised concerns about privacy and data security.
While this is expected to provide the highest possible security, it should be noted that it can also be susceptible to being hacked on the Internet.
8. How Smart Cities Work:
Smart City is a hot topic nowadays. Why?
The reason is simple: smart cities have advanced city life with advanced technologies compared to other cities. Cities follow four steps to improve quality of life.
For this, they enable economic growth by connecting IoT devices and networks of other technologies.
8.1. The Collection –
New technology smart sensors collect more information such as real-time data.
8.2. Examination –
Data analysis is done to get better reports on the management of various services and operations of the city.
8.3. Transmission –
Improved communication makes it easier to convey the results of data analysis to decision-makers.
8.4. Activity –
A developed city works only when the right decisions are taken by the government. Besides, the government’s assistance in managing the various resources of the city and improving the quality of life of the city’s residents is of utmost importance.
And the ICT framework helps the most in this regard, which integrates real-time data from connected assets, objects, and machines to make the right decisions.
Even the people of the city have been able to stay connected with the developed ecosystem of the smart city, using various new smart technologies and devices.
Through which city data and city infrastructure help citizens immensely.
Using these devices, can effect to reduced high range. Also it help to improve a better sustainability, distribute energy and collect waste and reduce congestion problems in a city.
A city’s smartness depends on its security system. But smart cities are as smart in technology as they are smart in security.
It has provided many benefits for security, such as connected surveillance systems, intelligent roadways, and public safety monitoring. But are there gaps that smart cities still need to fix?
As smart cities run on technology, they must guard against cyber attacks, hacking, and data theft. There is also a need to repeatedly confirm that the reported data is correct.
This requires implementing measures such as physical data vaults, resilient authentication management, and ID solutions. Even governments, private sector enterprises, software developers, device manufacturers, energy providers, and network service managers must work together to determine integrated solutions with key security objectives.
9. Examples of Smart Cities:
Examples of smart cities Gradually, many cities around the world are now starting to implement smart technologies, with some cities at the forefront of development.
The Singapore city-state uses sensors and IoT-enabled cameras to monitor the cleanliness of public spaces, crowd density, and the movement of locally registered vehicles.
The city’s smart technology also helps companies and residents monitor energy consumption, waste generation, and water consumption in real-time. The city of Singapore has also added an elderly monitoring system with robotic buses to ensure the health and well-being of its senior citizens.
Kansas City took steps to make it a smart city. That includes smart streetlights, interactive kiosks, and free Wi-Fi on over 50 blocks of the city’s two-mile streetcar route. There are also available parking spaces, traffic flows, and pedestrian hotspots made publicly available through city data visualization apps.
9.3. San Diego:
The city of San Diego installed 3,200 smart sensors in early 2017 to help optimize traffic and parking and improve public safety, environmental awareness, and the overall quality of life for residents. Even as solar-to-electric charging stations are available to boost the use of electric vehicles, connected cameras are very helpful in monitoring traffic and identifying crimes.
Dubai is one of the most developed cities. The city has used smart city technology for traffic routing, parking, infrastructure planning, and transportation in the UAE to improve itself. In addition, the city has developed telemedicine and smart healthcare, as well as smart buildings, smart utilities, and smart education to develop the city further.
9.5. Other Smart Cities:
- Columbus, Ohio
- New York City, New York
- Toronto, Canada
- Vienna, Austria
- Barcelona, Spain
- Tokyo, Japan
- Reykjavik, Iceland
- London, England
- Melbourne, Australia
- Hong Kong, China
10. The Intention of Having Smart Cities:
Each smart city advances its development based on a specific aim. The goals of a smart city are to improve the efficiency of the policy, reduce wastage and inconvenience, improve social and economic quality, and maximize social inclusion.
But a key element of a smart city is valuing citizen participation.
11. Smart City Technologies:
Smart cities are more popular for their technology. Cities are connected to the Internet of Things (IoT) and various software, user interfaces, and communication network management for their public.
Another one of the most important is IoT. IoT is a network of connected devices that help communicate and exchange information. Data collected through these devices is stored within the server. It helps in improving efficiency in both the public and private sectors.
IoT devices have added processing called edge computing. This ensures that the most important and relevant information can be added through the network.
However, a robust security system is also required to protect, monitor and control network traffic within the computing system.
These systems allow IoT networks to transmit data continuously within the smart city network, securely preventing unauthorized access to city data.
Other technologies are:
- Application Programming Interface (API)
- Artificial Intelligence (AI)
- Cloud computing
- Machine Learning (ML)
- Machine to Machine (M2M)
- Mesh network
One of the biggest challenges smart cities may face is connectivity. Thousands or millions of AI devices are scattered across the city, which without a solid connection, can go haywire, and the smart city itself will be dead.
Well, public transit, traffic management, public safety, water and waste management, electricity, and natural gas supply can be unreliable, especially as a system ages and grows. However, the importance of such activities will only increase as the city expands and demand for its infrastructure increase. These systems must be continuously maintained and tested to ensure their proper functioning.
Smart city projects should be transparent and available to citizens through an open data portal or mobile app. It allows residents to connect to data and complete personal tasks such as paying bills, finding efficient transportation options, and assessing home energy consumption.
This requires a robust and secure data collection and storage system to prevent hacking or misuse. Smart city data also needs to be anonymized to avoid privacy issues.
