Blockchain for Smart Mobility—Literature Review and Future Research Agenda

Abstract

Today’s cities face numerous challenges due to climate change and urbanization. The concept of a smart city aims to help cities to address these challenges by adapting modern information and communication technology. Smart mobility and transportation form one important aspect of smart cities. Inefficient mobility in cities can lead to problems such as traffic congestion, which results in frustration for residents and a decrease in the quality of life. Against the backdrop of global warming, cities also strive to reduce CO2 emissions, an attempt which requires sustainable and novel mobility concepts. Blockchain is a current technology, said to have huge potential, that is being investigated for application in many facets of smart cities. In the context of smart mobility, blockchain can be used for transactions relating to ridesharing and electric charging, handling of interactions of platoon members, or serving as a foundation for communication between vehicles. Although initial research about this topic exists, it is distributed among different use-cases and applications. This article conducts a systematic literature review to analyze blockchain’s role in mobility and transportation in smart cities, and its potential to increase efficiency in these areas. With this review, we aim to consolidate and summarize the current knowledge about this topic. As a first result, we present the findings from our literature review, which can be divided into five categories of use-cases. We also present a platform for further research about this emerging topic by identifying promising future research avenues. For this purpose, we derive a future research agenda based on our findings.

Artificial Intelligence for Cancer Detection—A Bibliometric Analysis and Avenues for Future Research

“…As outlined above, AI systems require a large amount of data to learn and to develop robust models. When it comes to data, it is additionally important to ensure the trustworthiness, reliability, and security of the sources or platforms the data stem from [103,104]. If malicious actors succeed in manipulating or changing the data that are used as an input for the AI system, this might affect the AI system's result.…”

Provendo Segurança em Cidades Inteligentes: Aplicações, Desafios e Tendências em Mobilidade Elétrica e Tarifação Inteligente com NFTs

“…Outros trabalhos também ressaltam a necessidade da identificação segura dos dispositivos na cadeia de blocos [Karger et al, 2021]. Yuan e Wang tratam diretamente a gestão de identificadores de veículos elétricos, propondo um modelo conceitual organi-zado em camadas para Sistema de Transporte Inteligentes (STIs) baseados em cadeias de blocos.…”

Blockchain revolution in the tourism industry: A semi-systematic literature review

“…Despite many publications on this topic in recent years, research remains fragmented and poorly integrated (Karger, Jagals & Ahleman, 2021). Previous reviews have focused on specific aspects such as applications during the COVID-19 pandemic (Pérez-Sánchez et al, 2021), digital transformation (Bodkhe, Tanwar & Alazab, 2020;Mustafaeva, Tappaskhanova & Thamitlokova, 2020), smart mobility (Karger et al, 2021), or a geographical area such as regional areas (Dokl, Rogelj & Bogataj, 2022). A more holistic approach would help to establish a framework for the main applications of BCT in tourism.…”
