The concept of the Internet of Things (IoT) has profoundly transformed connectivity by enabling data to be exchanged between physical objects over the Internet. However, the IoT operates primarily at the network layer, facilitating communication between devices without standardizing their interaction at the application level. The Web of Things (WoT), as an extension of the IoT, operates at the application layer using open, standardized Web technologies, leading to the emergence of new technologies such as the Web of Vehicles (WoV). As we know, Vehicular Ad hoc NETworks (VANETs) are part of the IoT. However, establishing connections in the context of VANET and securing data against potential attacks has become a real challenge: How do we provide access to all these services while protecting resources from attacks by unwanted users? Intelligent Transport Systems (ITS) is the first solutions to ensure the management of urban mobility. Nevertheless, these systems face many challenges in terms of traceability, antifraud, and delay management. These issues can be addressed using Blockchain technology. This chapter presents a review of the literature and a new classification that analyzes and synthesizes existing research on the use of blockchain in ITS and WoT.
