A Blockchain-Based Integrated Vehicle Registration and License Plate Verification System for Road Traffic Governance in Nigeria

This study presents a blockchain-based integrated vehicle registration and license plate verification system designed to address persistent challenges in road traffic governance in Nigeria, including document forgery, fragmented databases, poor inter-agency coordination, and delayed vehicle verification. The proposed system integrates vehicle registration data and license plate licensing records into a decentralized blockchain-enabled platform accessible to authorized enforcement agencies through web and mobile interfaces. Using a Rapid Application Development methodology, the system was implemented with HTML, JavaScript, PHP, and a private blockchain ledger to ensure data immutability, transparency, and trust. Experimental evaluation using sampled vehicle records from Rivers State demonstrates improved verification speed, enhanced data integrity, and reduced susceptibility to fraud. The study contributes to e-governance and intelligent transportation systems literature by demonstrating the feasibility of blockchain adoption in public-sector vehicle administration within a developing economy context.
