Making Toll Charges Collection Efficient and Trustless: A Blockchain-Based Approach

The paper attempted to combine the road toll charges collection systems and blockchain technology to examine how well these two concepts could fit together in terms of better functioning and security. Toll plazas in India have a colossal rush and are always questionable for their service and the actual amount of payment collection. To avoid the hustle and cash payment in the current situation, go for the e-payment system. This will really help to avoid carrying cash amount as well change of money. But the constraints are required internet for the execution of e payment system. In this system, we need trend people, standard procedures for the payment system, and enhanced technologies. An entire financial exchange is based on a bank and its network link. But the bank has a centralized system, and sometimes it is not secure. This research work proposed the toll payment system based on blockchain to provide a safer and manageable system. As the blockchain feature, this proposed model is secure and least chance to temple the data. In the working process of this system, we use mobile to read QR codes at the toll plaza for the payment. The system uses a smart contract to pay as per the traveling distance covered by the vehicle, and every toll system has a record of these transactions.
