Abstract
As smart cities (SCs) emerge, the Internet of Things (IoT) is able to simplify more sophisticated and ubiquitous applications employed within these cities. In this regard, we investigate seven predominant sectors including the environment, public transport, utilities, street lighting, waste management, public safety, and smart parking that have a great effect on SC development. Our findings show that for the environment sector, cleaner air and water systems connected to IoT-driven sensors are used to detect the amount of CO2, sulfur oxides, and nitrogen to monitor air quality and to detect water leakage and pH levels. For public transport, IoT systems help traffic management and prevent train delays, for the utilities sector IoT systems are used for reducing overall bills and related costs as well as electricity consumption management. For the street-lighting sector, IoT systems are used for better control of streetlamps and saving energy associated with urban street lighting. For waste management, IoT systems for waste collection and gathering of data regarding the level of waste in the container are effective. In addition, for public safety these systems are important in order to prevent vehicle theft and smartphone loss and to enhance public safety. Finally, IoT systems are effective in reducing congestion in cities and helping drivers to find vacant parking spots using intelligent smart parking.
Highlights
While old, crowded cities are under pressure from many issues such as population explosion and improper infrastructure, the rise of smart cities (SCs) has provided a good solution for solving many of the existing problems and overcoming urban challenges [1]
As we are faced with various barriers and problems across seven specific sectors in SCs, i.e., environment, public transport, utilities, street lighting, waste management, public safety, and parking, we believe that the utilization and implementation of the Internet of Things (IoT) will be effective in mitigating or resolving the problems associated with these areas
According to the McKinsey Global Institute, emissions can be reduced by 10–15% through applications that focus on building automation, mobility, and dynamic electricity pricing
Summary
While old, crowded cities are under pressure from many issues such as population explosion and improper infrastructure, the rise of smart cities (SCs) has provided a good solution for solving many of the existing problems and overcoming urban challenges [1]. In developing SCs, we are faced with numerous barriers and problems in various areas, such as roadways, environment, utilities, parking, public safety, waste management, and public transport, it is pertinent to enhance these sectors through accurate investigation and practical actions [5] To overcome such barriers, SC governments must implement appropriate strategies and present proper solutions to mitigate or eliminate these barriers [6]. With regard to the importance of transportation systems in SCs, the prospect of handling considerable information using sensor data from the environment for better monitoring of transport systems in SCs was examined by AlZubi et al, as the time data extracted from sensors is important; the researchers presented a responder-dependent add-on information fusion scheme concerning sensor data This guided vehicle scheme can observe the responding sensor information in order to determine the success of the goal endorsed.
