Cities are constantly transforming and, consequently, attracting efforts from researchers and opportunities to the industry. New transportation systems are being built in order to meet sustainability and efficiency criteria, as well as being adapted to the current possibilities. Moreover, citizens are becoming aware about the power and possibilities provided by the current generation of autonomous devices. In this sense, this paper presents and discusses state-of-the-art transportation technologies and systems, highlighting the advances that the concepts of Internet of Things and Value are providing. Decentralized technologies, such as blockchain, are been extensively investigated by the industry, however, its widespread adoption in cities is still desirable. Aligned with operations research opportunities, this paper identifies different points in which cities’ services could move to. This also study comments about different combinatorial optimization problems that might be useful and important for an efficient evolution of our cities. By considering different perspectives, didactic examples are presented with a main focus on motivating decision makers to balance citizens, investors and industry goals and wishes.

The growing presence of Distributed Generation has kept alive the discussions for the active integration of medium/low-voltage power consumers into the energy market. Besides technical and economic difficulties faced so far, another point of view emerges from the use of blockchain technologies to make the Transactive Energy approach a reality. The current article presents a distributed application model for energy management and trade between members of a shareable consumption group, a kind of Distributed Generation regulated by the Brazilian Government. It also showcases the methodology of the crypto-currency Sharing Electricity in Brazil that can be used to allow power exchange operations at the scope of micro/mini-grids.
