Abstract
With the continuous development of Internet of things, all kinds of smart systems are quickly evolving to make our day-to-day life smoother and safer. Like many other sectors, transportation has entered a period of rapid change. Intelligent Traffic System is one of the fastest-growing fields within the smart systems, which is expected to increase road safety, mitigate traffic congestion, and enable fuel efficiency. The main functionalities of Intelligent Traffic System are as follows: (1) monitoring real-time traffic conditions in specific areas, (2) locating traffic emergencies (i.e. traffic accidents) in specific areas, and (3) dynamic monitoring and managing the continuous use in public transit services (i.e. change in car lanes) that may lead to changes in macro traffic conditions. This article will use the above-mentioned functionalities of the Intelligent Traffic System as underlying simulative scenarios, to design and to implement a smart transportation system based on Internet of things and blockchain—both share inherent distributed technology characteristics—combining both Internet of things sensor nodes and distributed ledger technology, to (1) record the changes in intelligent transportation systems and (2) set up a credit-token mechanism for paying the use and misuses in public transit services accordingly. The Intelligent Traffic System described in this article is intended to be used as experimental project only, given the terms and conditions as depicted in the simulated scenario. In real-life traffic scenarios, it may generate more complex system and data security issues, which will be elaborated and analyzed at the end of this article. Intelligent Traffic System is a comprehensive smart system; it can significantly change and reinvent the wheel for traffic conditions. Based on the system development as discussed in this article, there are still a lot of demands and challenges that need to be addressed in the future. Such topic scope will be explored in depth in our subsequent research.
Highlights
It is the solid fact that with the rapid development of Internet of things (IoT) technology, the number of connected devices is growing exceptionally
There is no difference between how an Roadside Unit (RSU) is usually used and the centric platform is the research on trusted token contract platform supported by blockchain
The blockchain-based Intelligent Traffic System (ITS) proposed in this article illustrates a comprehensive solution that contains (1) IoT devices integrated by Internet of vehicles (IoV) nodes, distributed processor nodes, and communication intermedia; (2) blockchainbased system deployed on BaaS to serve the data and payment transactions; and (3) ITS itself as a software to support the whole solution
Summary
It is the solid fact that with the rapid development of Internet of things (IoT) technology, the number of connected devices is growing exceptionally. An RSU is always a vital part of any VANET which is mainly responsible for tasks such as traffic monitoring, lane flow surveillance, as well as a data node transceiver between the cloud-based platforms and vehicles, and is a possible powerful router/AP for each data source node (vehicle/automobile) in order to provide a relatively stable network connection.[4] In this case, there is no difference between how an RSU is usually used and the centric platform is the research on trusted token contract platform supported by blockchain.
