A Blockchain-Based Architecture for Traffic Signal Control Systems
Wanxin Li, Mark Nejad, Rui Zhang
Ever-growing incorporation of connected vehicle (CV) technologies into
intelligent traffic signal control systems bring about significant data
security issues in the connected vehicular networks. This paper presents a
novel decentralized and secure by design architecture for connected vehicle
data security, which is based on the emerging blockchain paradigm. In a
simulation study, we applied this architecture to defend the Intelligent
Traffic Signal System (I-SIG), a USDOT approved CV pilot program, against
congestion attacks. The results show the performance of the proposed
architecture for the traffic signal control system.
