Air quality improvement by employing smart traffic management system controlled by internet of things for Botswana in the sub Saharan region of Africa

The rapid urbanization of towns and villages had led to the development of smart traffic control systems to reduce traffic congestion. Rapid urbanization increases the number of vehicles, which results in air pollution, additionally with the traffic. It's the most formidable challenge for humans to control the traffic and air pollution, and it is beyond the control of humans. Many steps are taken for traffic management and air pollution control. The principle of smart cities comes from the utilization of Information and Communication Technology (ICT) using the interconnection of physical devices over the internet. The constraints faced during traffic management, where the population is denser, lead to misleading information and accidents. The smart traffic control system using ICT and IoT overcomes the challenges confronting the elimination of such abnormalities and helps to manage traffic congestion efficiently. This paper describes the smart traffic control system model developed using the IoT infrastructure aids low budget control to both the urban and rural environment irrespective of the infrastructure.
