Comparative Study of Emerging Internet-of-Things in Traffic Management System

In recent years, the Internet-of-Things (IoT)-based traffic management system (ITMS) has attracted the attention of researchers from different fields, such as the automotive industry, academia and traffic management, due to its ability to enhance road safety and improve traffic efficiency. ITMS uses the Vehicle Ad-hoc Network (VANET) to communicate messages about traffic conditions or the event on the route to ensure the safety of the commuter. ITMS uses wireless communication technology for communication between different devices. Wireless communication has challenges to privacy and security. Challenges such as confidentiality, authentication, integrity, non-repudiation, identity, trust are major concerns of either security or privacy or both. This paper discusses the features of the traffic system, the features of the traffic management system (TMS) and the features of IoT that can be used in TMS with its challenges. Further, this paper analyses the work done in the last few years with the future scope of IoT in the TMS.
