Indeed, smart cities are the world's future. However, many developed countries have integrated it into their existing and master socio-economic plan, while other developing and underdeveloped nations are yet to grapple a knowledge of it. The fundamental idea of a smart city is to improve the standard of living, achieve economic growth, and increase people's quality in all nations. The steps to actualizing these are providing housing for all persons, upgrading the infrastructure and the associated services provided to the people, monitoring and controlling pollution due to congestion and illegal activities, making efficient transport options, and increasing the output efficiency of governance. The benefits are as follows;
On this premise, I call the "global village" a "small village" even as we anticipate the population of the world will reach 10 billion by 2050. This unprecedented population will be challenged by rural-urban drift, thereby causing cities to be responsible for the people. Nevertheless, challenges that will emanate due to the growing population can be comfortably accommodated by the smart city concept. These concepts are as follows;
Smart Healthcare System
Humanoid robots should be engaged in the movement of files, drugs, blood samples, and other laborious work activities. In some medical institutions, robotic machines already ease surgery operations by remote surgery with distinct precision. More so, patients geolocation will be used in the hospital facility to locate where a particular patient is and remotely monitor the recuperation progress.
Access to Transparent Data
Governments and organizations are already collecting millions of data from series of programs like citizens' information relating to the consumption rate, budgets, traffic, and geographical location. The quantity of profiles is so much, making it challenging to identify people, which is why it is called Big Data. In this case, the data should be categorized, and overviews created so that citizens can have access to them.
Optimized Electric and Networked Transport
Reducing the emission of carbon dioxide from cars into the atmosphere is paramount in developing smart cities. This can be achieved by restructuring the transportation network to cut down the mobility of vehicles. Also, apart from speed trains, electric buses should be used with sensors installed in them and the traffic lights to enable identification and control of bus passage and reduction of travel time.
Controlled Electricity Bills
Smart metering devices can harness direct monitoring and control of utilities such as gas, light, and water. This will minimize expenditure for consumers and save more energy.
Automated Street Lighting System
This is already a project been used in so many cities. It uses sensors and actuators to put on the lights when it's dark and put them off when the environment gets bright. It is another way of achieving smart energy saving.
Automated Railway Crossing System
Sensors will be used to detect when the train arrives or about the depart. These sensors send signals to a microcontroller, which is programmed to move the gates automatically. This will boost the technology used on railway lines help to reduce accidents.
Utilization of Programmed Education
Education is the basis of civilization as it is the point where all other activities interface. The capacity to actualize smart cities will be based on the teaching of computer programming languages for robot and software programs to children who are the future of the cities.
Home Automation System
Bluetooth module, relay and control switches, and microcontroller are the devices installed at homes to operate appliances autonomously. Usage of the Bluetooth technology on a smartphone, the machines can be controlled remotely, from the security lights around the building, power switches for television, air conditioner, heater, etc.
Smart Traffic Lights
Congestion of roads is a significant issue in road traffic management as the travel time for people, goods and services are increased. But implementing an automated process on traffic lights that can be adaptable to an emerging situation can help solve the problem.
Smart Water Monitoring System
The IoT integrated Smart Water Monitoring System senses the flow and pressure of water and records the flow volume per unit time. This data is that collected in the cloud to be stored and analyzed for further usage.
In conclusion, smart cities are the future incorporating information and communication technology used to harness devices' intelligent operation, leading to the incremental improvement of the human standard of living.
