Determining the Cyber Security Risks and Mitigation of those Vulnerabilities of Traffic Light Systems
Traffic signals used to be just hardware devices that ran on fixed schedules but now they have evolved into advanced network systems. Nowadays intelligent transportation systems are an essential part of ongoing evolution of smart cities which looks mainly at traffic planning and traffic management. Smart traffic lights do play an important role in traffic management. In recent studies, it is proven that many traffic lights deployed in practice have many vulnerabilities which is easy for an attacker to cause accidents and also traffic congestions. Field devices such as traffic signals, toll tag readers, cameras, and roadside equipment are quite susceptible to tampering. This is often due to their location in remote and isolated public spaces. In this paper we discuss mainly about the security issues present in traffic systems and the way with which it can be solved and enhanced and put into real time usage.
