Traffic congestion is a major concern in many cities. Failure to heed signals, poor law enforcement, and bad traffic light management are main factors that have led to traffic congestion. One of the most important problems in cities is the difficulty of further expanding the existing infrastructures. Having that in mind, the main accessible and available alternatives that could provide better management of the traffic lights is to use technological systems. There are many methods available for traffic management such as video data analysis, infrared sensors, inductive loop detection, wireless sensor networks, and a few other technologies. This research is focused on reviewing all these existing methods and studies using a systematic literature review (SLR). The SLR was intended to improve the synthesis of research by introducing a systematic process. This article aims at analyzing and assessing the existing studies against selected factors of comparison. The study achieves these aims by analyzing 78 main studies. The research outcomes indicated that there are decent numbers of studies that have been proposed in the area of smart traffic light management. However, less attention has been paid on the possibility of investigating the use of live traffic data to improve the accuracy of traffic management.

2. Research Background And Overview

Smart road systems use communication between vehicles and infrastructure in order to reduce congestion and environmental impact and improve traffic through this communication and cooperation and coordination between vehicles and other elements on the road in addition to the control of vehicles and transfer functions of the driver to the vehicle (Varaiya, 1993). Smart City means the interaction and cooperation between the components of the city such as traffic system, which uses internet of things (IoT) to deal with the different components of the city, where communication between these components becomes easy. Intelligent Transportation system (ITS) focuses on important elements such as transport management system, control and transport problems solutions. ITS is important in reducing congestion, accidents, risks, air pollution, increasing traffic safety, smoothing traffic flow, and identifying appropriate speeds and destinations. This section explains some essential concepts and backgrounds that are required to understand this research.
