Secure Blockchain Model for Vehicles toll Collection by GPS tracking: A case study of India

This paper aims to implement a blockchain-based, fully decentralized vehicle toll collection model. The resultant scheme uses a Global positioning system to track the vehicles, and the payment module is fully decentralized and uses Ethereum blockchain. Ethereum blockchain uses immutable documents called smart contracts to carry out business logic. It ensures that every transaction between vehicle owners and the authorities is traceable, immutable, transparent, and trustworthy. The Global Positioning System provides the location of an object using coordinates measured using satellites. The data from GPS is recorded constantly to ensure that the vehicle has traveled to the correct location and is stored in a publicly verifiable blockchain. The other vehicle owners work as location verifiers except for the particular vehicle. An automatic payment system is to be developed, which gets triggered when necessary conditions are met by the vehicle. Our proposed model is authentic and secure, ensuring penalties for malicious participants. The experimental results are based on the Gas consumption of all the smart contracts. This model can improve the current toll collection model of the National Highway Authority of India to make it more profitable and corruption-free.
