Integrating Blockchain and IoT/ITS for Safer Roads

Road safety continues to be a great concern despite various advances and initiatives. Sweden introduced the SS approach in 1996 as part of a plan to eliminate road fatalities and injuries. Since then, SS has been internationally adopted by the World Health Organization. In this article, we describe how the SS approach offers a holistic structure of various innovative solutions in the context of IoT and ITS. We also introduce a necessary extension to the SS approach considering emerging technologies such as connected and computing vehicles and vehicle autonomy. To facilitate this extension, we show how blockchains can play a crucial role in ensuring road safety, as well as the safety of its connected elements.
